The topics on the final test are variables, data analysis and sampling
A,) Variables
Independent variable is known as manipulated/ experimental variable. That is because the researcher can control the variable and it is presumed as caused of changes in another variable.
Dependent variable is also known as outcome variable. It is being observed or measured.
Intervening variable or mediating variable is the variable that comes between other variables which explain the relationship between independent and dependent variables.
Moderating variable is a variable that may change the independent variable.
B.) Data Analysis
Independent sample t-score - two groups, one independent, 1 dependent
One way Annova- three or more groups, one independent, one dependent
c.) Sampling
Probability (Random) sampling

c.) Sampling
Probability (Random) sampling
- simple random sampling - same probability
- stratified sampling - subgroups
- cluster sampling - subject in a block
non probability (non random) sampling
- convenience sampling - available and easy
- purposive sampling - certain characteristics
- snowball sampling- suggested by someone from interview
