What is an aim?

What does operationalize mean?

What is an independent variable?
The characteristic of an experiment that is manipulated or changed by researchers, not by the other variables in the experiment
What is a dependent variable?

What is a hypothesis?
A precise, testable statement of what the researchers predict will be the outcome of the study.
What is a null hypothesis?
It states that there is no relationship between the variables being studied
What is a target population?
The population that a study is intended to research and to which generalisations from samples are to be made
What is a sampling frame?
The population that the researcher is interested in
What is opportunity sampling?
When you use people who are available at the time for a study
What is systematic sampling?
When you select every nth person from a list to be your participant
What is stratified sampling?
A method of sampling that involves the division of a population into smaller sub groups known as strata
What is quota sampling?
Researchers make sub populations that reflect proportions of the target population and participants are allocated to the sub populations through opportunity sampling
What is self selected sampling?
Respondents choose whether to take part
What is snowball sampling?
A recruitment technique in which research participants are asked to assist researchers in identifying other potential subjects
What is time sampling?
During observation, you record data or behaviour at a time interval e.g. once every 30 seconds
