a) standard deviation

b) reciprocal determinism

c) correlation coefficient

d) factor analysis

Factor analysis

Explanation:

Factor analysis is a process that is being used in statistical phenomena. It is a procedure through that a researcher reduces the number of variable in the fewer number of the factor. This is the technique that extracts the common variable from all variable and put them into the common score. It is part of the general linear model. This method also assumes related to the many assumptions.

Thus here the researcher used the statically analysis named factor analysis for reflecting extroversion.
