Designs and variables in psychological research

Question 1

What are the 4 forms of research

Answer 1

1) observational techniques
2) interviews and surveys
3) correlational research (finding correlation between variables)
4) experimental research (measures effects of a change)

Question 2

What is the difference between qualitative and quantitative data

Answer 2

Qualitative data is an observation or interpretation or descriptive data. Whereas quantitative data contains numerical or statistical results which can be quantified

Question 3

What are the 2 types of variables? with explanations

Answer 3

1) Continuous variables which exist on a continuum
2) Categorical variables where there are specific categories to be classified as. These can be in any order

Question 4

What are the 3 types of experiment designs with explanations?

Answer 4

1) Frequency: how many people fit under each category- banner
2) Experimental: changing an independent variable to see if it creates any changes.
3) Correlational: there are not independent of dependent variables, measure what is naturally occurring to see if there is any relation. They must be continuous variables with increase or decrease. Correlation does not mean causation.

Question 5

Types of experimental designs with explanations

Answer 5

1) Experimental design: participants are randomly allocated a group
2) quasi- experimental design: groups are pre- defined by characteristics.

AND

1) Independent measures design: separate groups complete experiment and results are compared.
2) Repeated measures design: participants repeat the experiment under different conditions.

Question 6

4 different ways to measure data and explanations

Answer 6

1) Nominal data: number of people belonging to a category.
2) Ordinal data: data is in order but intervals may not be consistent.
3) Interval data: in order with fixed intervals and negatives.
4) Ratio data: in order with fixed intervals but no negatives .
