# Factor Analysis Flashcards

Define construct

An explanation of something that is not directly observable, but is created to understand or explain a phenoma

What are other words used instead of CONTEXT

Factors

latent variables

Define items

Specific questions or statements on a larger questionnaire that are ‘filling in’ for the construct of interest

ex. ‘I feel sad’ would fill the construct of ‘sad’

What are five response scales used in psychology?

Dichotomous scale

Likert scale

Unipolar scale

bipolar scale

visual analogue scale

What is a dichotomous scale?

Not really a scale- asks close ended questions (yes/no answers) therefore someone may not be able to truly represent themselves

What is correlation?

measures the relative strength of the linear relationship between two variables

What is considered a weak correlation

0

What is considered an insignificant effect size

r=+/- 0.1

What is considered a medium effect size?

r=+/-0.3

What is considered a large effect size?

r=+/-0.5

What is the average effect size in social psychology?

R=0.21

If your r is larger than ___ it means you are essentially measuring/comparing identical factors

0.8

What is a correlation coefficient

another way to present the effect size.

essentially is r. r is the slope of the linear regression analysis (the line on the graph) r is always between -1 and 1, with 0 meaning no correlation whatsoever

How can you find r?

absolute value of the correlation r can be found from R^2

can calculate the slope of the linear regression of two standardized variables
