Aims and Hypotheses

Last updated 22 Mar 2021

Observations of events or behaviour in our surroundings provoke questions as to why they occur. In turn, one or multiple theories might attempt to explain a phenomenon, and investigations are consequently conducted to test them. One observation could be that athletes tend to perform better when they have a training partner, and a theory might propose that this is because athletes are more motivated with peers around them.

The aim of an investigation, driven by a theory to explain a given observation, states the intent of the study in general terms. Continuing the above example, the consequent aim might be “to investigate the effect of having a training partner on athletes’ motivation levels”.

The theory attempting to explain an observation will help to inform hypotheses - predictions of an investigation’s outcome that make specific reference to the independent variables (IVs) manipulated and dependent variables (DVs) measured by the researchers.

There are two types of hypothesis:

• - H 1 – Research hypothesis
• - H 0 – Null hypothesis

H 1 – The Research Hypothesis

This predicts a statistically significant effect of an IV on a DV (i.e. an experiment), or a significant relationship between variables (i.e. a correlation study), e.g.

• In an experiment: “Athletes who have a training partner are likely to score higher on a questionnaire measuring motivation levels than athletes who train alone.”
• In a correlation study: ‘There will be a significant positive correlation between athletes’ motivation questionnaire scores and the number of partners athletes train with.”

The research hypothesis will be directional (one-tailed) if theory or existing evidence argues a particular ‘direction’ of the predicted results, as demonstrated in the two hypothesis examples above.

Non-directional (two-tailed) research hypotheses do not predict a direction, so here would simply predict “a significant difference” between questionnaire scores in athletes who train alone and with a training partner (in an experiment), or “a significant relationship” between questionnaire scores and number of training partners (in a correlation study).

H 0 – The Null Hypothesis

This predicts that a statistically significant effect or relationship will not be found, e.g.

• In an experiment: “There will be no significant difference in motivation questionnaire scores between athletes who train with and without a training partner.”
• In a correlation study: “There will be no significant relationship between motivation questionnaire scores and the number of partners athletes train with.”

When the investigation concludes, analysis of results will suggest that either the research hypothesis or null hypothesis can be retained, with the other rejected. Ultimately this will either provide evidence to support of refute the theory driving a hypothesis, and may lead to further research in the field.

Aims, Hypotheses & Sampling

Aims and hypotheses.

Each research study specifies aims and hypotheses. An aim is what it is trying to achieve, while a hypothesis is a specific prediction of what it will find.

• A researcher usually states the aim of their study.
• This involves saying what they are trying to achieve, or what the point of their study is.
• For example, a researcher may state that they aim to find out the effect of caffeine on sleep.

• A hypothesis is different from an aim.
• It involves making a specific prediction of what will be found, expressed in terms of a change in variables.
• For example, a researcher may state a hypothesis that consuming 200mg of caffeine will increase the length of time it takes people to fall asleep compared to having no caffeine.

Experimental vs alternative

• In an experiment, the researcher’s main hypothesis is known as an experimental hypothesis. It is also referred to as H1.
• In a non-experimental study, it is typically called an alternative hypothesis.

Null hypothesis

• Most studies also clearly state a null hypothesis (sometimes referred to as H0).
• This is a statement of what will be found if the experimental/alternative hypothesis is not supported by the results.

Directional hypothesis

• A directional or one-tailed hypothesis predicts the direction in which change is expected to occur.
• It is used when previous research has suggested the direction of change.
• e.g.Alcohol increases reaction times.

Non-directional hypothesis

• A non-directional or two-tailed hypothesis simply predicts change and does not specify direction.

It is used when there is no previous research. It is non-specific and uses words like: effect, change, difference etc.

• e.g. Alcohol will affect reaction times.

NB. All variables must be fully operationalised e.g. alcohol measured in units; reaction times measured in seconds.

Populations and Samples

Any research study needs a group of participants. These are called the sample, and they are drawn from a wider group called the target population.

• Sampling means selecting a group of participants who will take part in the study.

Populations

• A sample always comes from a broader population.
• This does not necessarily mean the whole population of a country, but could be a specific group.
• For example, all sixth-form school pupils in the country is an example of a target population, and a selection of 50 sixth-form school pupils is an example of a sample.

Representation

• A key aspect of sampling is that the sample should be representative of the target population.
• This means that they should have similar characteristics.
• Studying a representative sample allows the researcher to generalise the findings to the target population. This is a key aim of any research.

Sampling Techniques

There are multiple ways of obtaining a sample for a research study. Four major sampling techniques are opportunity sampling, systematic sampling, volunteer sampling and stratified sampling.

Opportunity sampling

• Examples of opportunity sampling include conducting research on the researcher’s own friends, classmates or students.
• Opportunity sampling is very prone to bias because the most easily available participants may not be representative of the target population.

Systematic sampling

• Examples of systematic sampling include picking every 50th person that walks along a corridor, or every 100th name in the phone book, or posting a questionnaire to every 10th house in a village.
• Systematic sampling reduces researcher bias, but some potential participants may be excluded e.g. because they are not in the phone book or do not live in a house. This leads to bias.

Volunteer sampling

• Eg. posting an advert on a school noticeboard, asking people to complete your online survey.
• One source of bias with volunteer sampling is that certain personalities are more likely than others to come forward and help the research. This may have affected classic research studies such as Milgram’s obedience research and Zimbardo’s Stanford Prison experiment.

Stratified sampling

• An example of stratified sampling would involve selecting people from different ethnic groups to create a sample with the same proportions as exist in the target population.
• This reduces bias by making the sample more representative, but before stratification can occur, participants must already have been selected using another sampling technique.

Random sampling

• In random sampling like the National Lottery, all members of the target population must stand an equal chance of being selected.
• E.g. putting the names of every member of the target population into a hat and pulling a sample out (without looking!).

Evaluation of random sampling

• If the sample is large enough, the rules of probability suggest that it should be representative.
• Participants may not be willing or able to take part in the research.
• Sample could still be biased in terms of variables such as gender, age, ethnicity etc.
