Research hypothesis examples

Scientists must generate a realistic and testable hypothesis around which they can build the experiment. Some examples could be:. Over-fishing affects the stocks of cod. If over-fishing is causing a decline in the numbers of Cod, reducing the amount of trawlers will increase cod stocks.

These are acceptable statements and they all give the researcher a focus for constructing a research experiment. Though the other one is perfectly acceptable, an ideal research hypothesis should contain a prediction, which is why the more formal ones are favored.

A scientist who becomes fixated on proving a research hypothesis loses their impartiality and credibility. Statistical tests often uncover trends, but rarely give a clear-cut answer, with other factors often affecting the outcome and influencing the results. Whilst gut instinct and logic tells us that fish stocks are affected by over fishing, it is not necessarily true and the researcher must consider that outcome.

Perhaps environmental factors or pollution are causal effects influencing fish stocks. A hypothesis must be testable , taking into account current knowledge and techniques, and be realistic. If the researcher does not have a multi-million dollar budget then there is no point in generating complicated hypotheses. A hypothesis must be verifiable by statistical and analytical means, to allow a verification or falsification.

This means that the research showed that the evidence supported the hypothesis and further research is built upon that. Your hypothesis should Be written in clear, concise language. Have both an independent and dependent variable. Be falsifiable — is it possible to prove or disprove the statement? Make a prediction or speculate on an outcome. Be practicable — can you measure the variables in question? Hypothesize about a proposed relationship between two variables, or an intervention into this relationship.

The research hypothesis is often also callen H 1 and opposes the current view, called the null hypothesis H 0. Mini quiz:. Consider the following hypotheses. Are they likely to lead to sound research and conclusions, and if not, how could they be improved? Adding mica to a plastic compound will decrease its viscosity. Those who drink a cup of green tea daily experience enhanced wellness. Prolonged staring into solar eclipses confers extrasensory powers.

A decline in family values is lowering the marriage rate. Children with insecure attachment style are more likely to engage in political dissent as adults. This is an ideal hypothesis statement. It is well-phrased, clear, falsifiable and merely by reading it, one gets an idea of the kind of research design it would inspire.

This hypothesis is less clear, and the problem is with the dependent variable. A better hypothesis might be: those who drink a cup of green tea daily display lower levels of inflammatory markers in the blood. Though this hypothesis looks a little ridiculous, it is actually quite simple, falsifiable and easy to operationalize. The obvious problem is that scientific research seldom occupies itself with supernatural phenomenon and worse, putting this research into action will likely cause damage to its participants.

When it comes to hypotheses, not all questions need to be answered! However, scientists should always be alert for their own possible biases creeping into research, and this can occur right from the start. Normative topics with moral elements are seldom neutral.

A better hypothesis will remove any contentious, subjective elements. A better hypothesis: decrease in total discretionary income corresponds to lower marriage rate in people 20 — 30 years of age. This hypothesis may yield very interesting and useful results, but practically, how will the researchers gather the data? Even if research is logically sound, it may not be feasible in the real world. A researcher might instead choose to make a more manageable hypothesis: high scores on an insecure attachment style questionnaire will correlate with high scores on a political dissention questionnaire.

Though complex, this is a good hypothesis. It is falsifiable, has clearly identified variables and can be supported or rejected using the right statistical methods. Check out our quiz-page with tests about:. For some research projects, you might have to write several hypotheses that address different aspects of your research question.

A hypothesis is not just a guess — it should be based on existing theories and knowledge. It also has to be testable, which means you can support or refute it through scientific research methods such as experiments, observations and statistical analysis of data. Hypotheses propose a relationship between two or more variables. An independent variable is something the researcher changes or controls.

A dependent variable is something the researcher observes and measures. In this example, the independent variable is apple consumption — the assumed cause. Writing a hypothesis begins with a research question that you want to answer. The question should be focused, specific, and researchable within the constraints of your project.

Do students who attend more lectures get better exam results? Your initial answer to the question should be based on what is already known about the topic. Look for theories and previous studies to help you form educated assumptions about what your research will find.

At this stage, you might construct a conceptual framework to identify which variables you will study and what you think the relationships are between them. Now you should have some idea of what you expect to find. Write your initial answer to the question in a clear, concise sentence. You need to make sure your hypothesis is specific and testable. There are various ways of phrasing a hypothesis, but all the terms you use should have clear definitions, and the hypothesis should contain:.

To identify the variables, you can write a simple prediction in if…then form. The first part of the sentence states the independent variable and the second part states the dependent variable. If a first-year student starts attending more lectures , then their exam scores will improve. In academic research, hypotheses are more commonly phrased in terms of correlations or effects, where you directly state the predicted relationship between variables.

The number of lectures attended by first-year students has a positive effect on their exam scores. If you are comparing two groups, the hypothesis can state what difference you expect to find between them. First-year students who attended most lectures will have better exam scores than those who attended few lectures. If your research involves statistical hypothesis testing , you will also have to write a null hypothesis. The null hypothesis is the default position that there is no association between the variables.

The null hypothesis is written as H 0 , while the alternative hypothesis is H 1 or H a. H 0 : The number of lectures attended by first-year students has no effect on their final exam scores. H 1 : The number of lectures attended by first-year students has a positive effect on their final exam scores.
