Define a one-tailed hypothesis.
Hypothesis where a specific effect is predicted (i.e. that results will go in one direction).
1 of 9
Define a two-tailed hypothesis.
A hypothesis where an effect is predicted but not specified i.e. results could go in either of two directions.
2 of 9
Define an alternate hypothesis.
A prediction that there will be an effect (e.g. of the independent variable on the dependent variable in an experiment; or that two variables will be related in a correlation study).
3 of 9
Define a null hypothesis
A prediction that there will be no effect (i.e. in an experiment the independent variable will not have predicted the effect on the dependent variable; in a correlation the two variables will not be related).

Give 2 strengths of repeated measures design.
1. Same person used in both conditions, therefore, participant variables reduced, so increased internal validity.
2. Same person used twice so do not need a big sample size for 2 different groups so you don't need to spend more money or time.
5 of 9
Give 2 weaknesses of repeated measures design.
1. Order effects such as practice, fatigue or boredom may affect results, so requires counterbalancing and therefore decreased internal validity.
2. If characters are tested twice they may work out the IV and therefore pick up demand characteristics and t

Give 3 strengths of qualitative data.
1. Close involvement with the participants which means you can get more detail that may not have been known otherwise. so increased internal validity.
2. Qualitative data can allow for you to discover cause and effect, and relationships.
3. Allows for con

Give 2 weaknesses of qualitative data.
1. Time consuming and costly so small sample size and data set.
2. Subjective results so decreased internal validity and hard to replicate so decreased reliability.
8 of 9
How can qualitative data be obtained?
- diary accounts
- interviews
documents
-focus groups
-case studies
-ethnography
