Sample of hypothesis in research proposal

So a researcher might hypothesize: "People with high-stress levels will be more likely to contract a common cold after being exposed to the virus than people who have low-stress levels. In other instances, researchers might look at commonly held beliefs or folk wisdom. The researcher might pose a specific hypothesis that "People tend to select romantic partners who are similar to them in interests and educational level.

When trying to come up with a good hypothesis for your own research or experiments, ask yourself the following questions:. Before you come up with a specific hypothesis, spend some time doing background research. Once you have completed a literature review, start thinking about potential questions you still have. Pay attention to the discussion section in the journal articles you read. Many authors will suggest questions that still need to be explored.

In order to form a hypothesis, you should take these steps:. In the scientific method , falsifiability is an important part of any valid hypothesis. Students sometimes confuse the idea of falsifiability with the idea that it means that something is false, which is not the case.

What falsifiability means is that if something was false, then it is possible to demonstrate that it is false. One of the hallmarks of pseudoscience is that it makes claims that cannot be refuted or proven false. A variable is a factor or element that can be changed and manipulated in ways that are observable and measurable. However, the researcher must also define how the variable will be manipulated and measured in the study.

For example, a researcher might operationally define the variable " test anxiety " as the results of a self-report measure of anxiety experienced during an exam. A "study habits" variable might be defined by the amount of studying that actually occurs as measured by time.

These precise descriptions are important because many things can be measured in a number of different ways. One of the basic principles of any type of scientific research is that the results must be replicable. Some variables are more difficult than others to define. How would you operationally define a variable such as aggression?

For obvious ethical reasons, researchers cannot create a situation in which a person behaves aggressively toward others. In order to measure this variable, the researcher must devise a measurement that assesses aggressive behavior without harming other people. In this situation, the researcher might utilize a simulated task to measure aggressiveness. Once a researcher has formed a testable hypothesis, the next step is to select a research design and start collecting data.

The research method depends largely on exactly what they are studying. There are two basic types of research methods: descriptive research and experimental research. Descriptive research such as case studies , naturalistic observations , and surveys are often used when it would be impossible or difficult to conduct an experiment. Once a researcher has collected data using descriptive methods, a correlational study can then be used to look at how the variables are related. This type of research method might be used to investigate a hypothesis that is difficult to test experimentally.

Experimental methods are used to demonstrate causal relationships between variables. In an experiment, the researcher systematically manipulates a variable of interest known as the independent variable and measures the effect on another variable known as the dependent variable. Unlike correlational studies, which can only be used to determine if there is a relationship between two variables, experimental methods can be used to determine the actual nature of the relationship—whether changes in one variable actually cause another to change.

The hypothesis is a critical part of any scientific exploration. It represents what researchers expect to find in a study or experiment. In situations where the hypothesis is unsupported by the research, the research still has value. Such research helps us better understand how different aspects of the natural world relate to one another. It also helps us develop new hypotheses that can then be tested in the future.

It specifies the expected direction to be followed to determine the relationship between variables, and is derived from theory. It does not predict the exact direction or nature of the relationship between the two variables. Non-directional hypothesis is used when there is no theory involved or when findings contradict previous research.

Associative hypothesis defines interdependency between variables. A change in one variable results in the change of the other variable. On the other hand, causal hypothesis proposes an effect on the dependent due to manipulation of the independent variable. It states that there is a relationship between the two variables of the study and that the results are significant to the research topic. A testable hypothesis is not a simple statement. It is rather an intricate statement that needs to offer a clear introduction to a scientific experiment, its intentions, and the possible outcomes.

However, there are some important things to consider when building a compelling hypothesis. Independent variables are the ones which are manipulated, controlled, or changed. Independent variables are isolated from other factors of the study. Dependent variables , as name suggests are dependent on other factors of the study. They are influenced by the change in independent variable. Example 1 The greater number of coal plants in a region independent variable increases water pollution dependent variable.

If you change the independent variable building more coal factories , it will change the dependent variable amount of water pollution. Example 2 What is the effect of diet or regular soda independent variable on blood sugar levels dependent variable?

If you change the independent variable the type of soda you consume , it will change the dependent variable blood sugar levels. You should not ignore the importance of the above steps. The validity of your experiment and its results rely on a robust testable hypothesis. Developing a strong testable hypothesis has few advantages, it compels us to think intensely and specifically about the outcomes of a study.

Consequently, it enables us to understand the implication of the question and the different variables involved in the study. Furthermore, it helps us to make precise predictions based on prior research. Hence, forming a hypothesis would be of great value to the research.

Here are some good examples of testable hypotheses.

Variables: During the planning stage, it is necessary to identify the key variables of the study and their method of measurement and unit of measurement must be clearly indicated. Four types of variables are important in research 5 :.

Independent variables: variables that are manipulated or treated in a study in order to see what effect differences in them will have on those variables proposed as being dependent on them. Dependent variables: variables in which changes are results of the level or amount of the independent variable or variables. For instance, in a study of the effect of measles independent variable on child mortality dependent variable , the nutritional status of the child may play an intervening confounding role.

Background variables: variables that are so often of relevance in investigations of groups or populations that they should be considered for possible inclusion in the study. For example sex, age, ethnic origin, education, marital status, social status etc. The objective of research is usually to determine the effect of changes in one or more independent variables on one or more dependent variables. For example, a study may ask "Will alcohol intake independent variable have an effect on development of gastric ulcer dependent variable?

Certain variables may not be easy to identify. The characteristics that define these variables must be clearly identified for the purpose of the study. A hypothesis can be defined as a tentative prediction or explanation of the relationship between two or more variables. In other words, the hypothesis translates the problem statement into a precise, unambiguous prediction of expected outcomes.

Hypotheses are not meant to be haphazard guesses, but should reflect the depth of knowledge, imagination and experience of the investigator. For example: "Health education involving active participation by mothers will produce more positive changes in child feeding than health education based on lectures". Here the independent variable is types of health education and the dependent variable is changes in child feeding.

A research question poses a relationship between two or more variables but phrases the relationship as a question; a hypothesis represents a declarative statement of the relations between two or more variables. For exploratory or phenomenological research, you may not have any hypothesis please do not confuse the hypothesis with the statistical null hypothesis. Is there a relationship between them? Deciding whether to use questions or hypotheses depends on factors such as the purpose of the study, the nature of the design and methodology, and the audience of the research at times even the outlook and preference of the committee members, particularly the Chair.

Methodology: The method section is very important because it tells your research Committee how you plan to tackle your research problem. The guiding principle for writing the Methods section is that it should contain sufficient information for the reader to determine whether the methodology is sound. Some even argue that a good proposal should contain sufficient details for another qualified researcher to implement the study. Research design: The selection of the research strategy is the core of research design and is probably the single most important decision the investigator has to make.

The choice of the strategy, whether descriptive, analytical, experimental, operational or a combination of these depend on a number of considerations, 5 but this choice must be explained in relation to the study objectives. Research subjects or participants: Depending on the type of your study, the following questions should be answered 3 , 5. The key reason for being concerned with sampling is the issue of validity-both internal and external of the study results.

Controls or comparison groups are used in scientific research in order to increase the validity of the conclusions. Control groups are necessary in all analytical epidemiological studies, in experimental studies of drug trials, in research on effects of intervention programmes and disease control measures and in many other investigations.

Some descriptive studies studies of existing data, surveys may not require control groups. Sample size: The proposal should provide information and justification basis on which the sample size is calculated about sample size in the methodology section. A smaller sample size than needed can also be unethical as it exposes human subjects to risk with no benefit to scientific knowledge.

Calculation of sample size has been made easy by computer software programmes, but the principles underlying the estimation should be well understood. Interventions: If an intervention is introduced, a description must be given of the drugs or devices proprietary names, manufacturer, chemical composition, dose, frequency of administration if they are already commercially available.

Ethical issues 3 : Ethical considerations apply to all types of health research. Before the proposal is submitted to the Ethics Committee for approval, two important documents mentioned below where appropriate must be appended to the proposal. In additions, there is another vital issue of Conflict of Interest, wherein the researchers should furnish a statement regarding the same. The Informed consent form informed decision-making : A consent form, where appropriate, must be developed and attached to the proposal.

The use of medical terminology should be avoided as far as possible. Special care is needed when subjects are illiterate. It should explain why the study is being done and why the subject has been asked to participate. It should describe, in sequence, what will happen in the course of the study, giving enough detail for the subject to gain a clear idea of what to expect. It should clarify whether or not the study procedures offer any benefits to the subject or to others, and explain the nature, likelihood and treatment of anticipated discomfort or adverse effects, including psychological and social risks, if any.

Where relevant, a comparison with risks posed by standard drugs or treatment must be included. If the risks are unknown or a comparative risk cannot be given it should be so stated. It should assure the participant of confidentiality of the findings. Ethics checklist: The proposal must describe the measures that will be undertaken to ensure that the proposed research is carried out in accordance with the World Medical Association Declaration of Helsinki on Ethical Principles for Medical research involving Human Subjects.

It is unethical to expose subjects to research that will have no value. The use of vulnerable subjects as research participants needs special justification. Vulnerable subjects include those in prison, minors and persons with mental disability. In international research it is important to mention that the population in which the study is conducted will benefit from any potential outcome of the research and the research is not being conducted solely for the benefit of some other population.

Justification is needed for any inducement, financial or otherwise, for the participants to be enrolled in the study. Risks are not limited to physical harm. Psychological and social risks must also be considered. Research setting 5 : The research setting includes all the pertinent facets of the study, such as the population to be studied sampling frame , the place and time of study.

Study instruments 3 , 5 : Instruments are the tools by which the data are collected. For new a questionnaire which is being designed specifically for your study the details about preparing, precoding and pretesting of questionnaire should be furnished and the document appended to the proposal. Descriptions of other methods of observations like medical examination, laboratory tests and screening procedures is necessary- for established procedures, reference of published work cited but for new or modified procedure, an adequate description is necessary with justification for the same.

Collection of data: A short description of the protocol of data collection. For example, in a study on blood pressure measurement: time of participant arrival, rest for 5p. This minimizes the possibility of confusion, delays and errors.

Data analysis: The description should include the design of the analysis form, plans for processing and coding the data and the choice of the statistical method to be applied to each data. What will be the procedures for accounting for missing, unused or spurious data?

Monitoring, supervision and quality control: Detailed statement about the all logistical issues to satisfy the requirements of Good Clinical Practices GCP , protocol procedures, responsibilities of each member of the research team, training of study investigators, steps taken to assure quality control laboratory procedures, equipment calibration etc. You put weeks, days or months at one side, and the tasks at the other.

You draw fat lines to indicate the period the task will be performed to give a timeline for your research study take help of tutorial on youtube. Significance of the study: Indicate how your research will refine, revise or extend existing knowledge in the area under investigation.

How will it benefit the concerned stakeholders? What could be the larger implications of your research study? Dissemination of the study results: How do you propose to share the findings of your study with professional peers, practitioners, participants and the funding agency? Indicate how will the study be financed. References: The proposal should end with relevant references on the subject. For web based search include the date of access for the cited website, for example: add the sentence "accessed on June 10, ".

Appendixes: Include the appropriate appendixes in the proposal. For example: Interview protocols, sample of informed consent forms, cover letters sent to appropriate stakeholders, official letters for permission to conduct research. Before you come up with a specific hypothesis, spend some time doing background research.
