a hypothesis that states that the IV will not affect the DV as they have no relationship between them
null hypothesis
1 of 17
the hypothesis the researcher tests by conducting a study and collecting data, which attempts to show the null hypothesis is not supported
alternative hypothesis
2 of 17
the factor which will b varied or changed in an experiment to look for an affect on the other variable
independent variable
3 of 17
the factor which will be measured in an experiment
dependent variable
4 of 17
a variable that is not the IV but may affect the DV if not controlled
extraneous variable
5 of 17
the large group of people the researcher wishes to study
target population
6 of 17
the small group of people who represent the target population and who are studied
sample
7 of 17
strategies used by researchers to obtain people from the target population t take part in their studies
sampling methods
8 of 17
sampling method where every member of the target population has an equal chance of being selected for the sample
random sampling
9 of 17
a sampling method whereby people who are members of the target population who are available and willing to take part in the research take part
opportunity sampling
10 of 17
every 'nth' member of the target population is selected for the sample
systematic sampling
11 of 17
the different subgroups in the target population are identified and then people are selected randomly from these groups in proportion to their numbers in the target population
stratified sampling
12 of 17
data in descriptive form such as verbal or written answers to questions, or observed behaviour
qualitative data
13 of 17
data in numerical form such as scores or times taken to do a task
quantitative data
14 of 17
where two or more separate groups of participants are used in an experiment; each group takes part in one of the conditions
independent groups
15 of 17
where only one group of participants is used in an experiment; this group takes part in both conditions
repeated measures
16 of 17
where people with similar qualities are grouped into pairs; each member of the pair takes part in a different condition
matched pairs
