How do you find the factor score in factor analysis?

Factor/component scores are given by ˆF=XB, where X are the analyzed variables (centered if the PCA/factor analysis was based on covariances or z-standardized if it was based on correlations). B is the factor/component score coefficient (or weight) matrix.

How do you do factor analysis?

First go to Analyze – Dimension Reduction – Factor. Move all the observed variables over the Variables: box to be analyze. Under Extraction – Method, pick Principal components and make sure to Analyze the Correlation matrix. We also request the Unrotated factor solution and the Scree plot.

They are often used as predictors in regression analysis or drivers in cluster analysis. SPSS FACTOR can add factor scores to your data but this is often a bad idea for 2 reasons: Factor scores will only be added for cases without missing values on any of the input variables.

When should we use exploratory factor analysis?

If Kaiser-Meyer-Olkin Measure of Sampling Adequacy is equal or greater than 0.60 then we should proceed with Exploratory Factor Analysis; the sample used was adequate. If Bartlett’s test of sphericity is significant (p < 0.05), we should proceed with the Exploratory Factor Analysis.

How many respondents do I need for factor analysis?

There is no significant answer to question “How many cases respondents do I need to factor analysis?”, and methodologies differ. A common rule is to suggest that a researcher has at least 10-15 participants per variable. Fiedel (2005) says that in general over 300 Respondents for sampling analysis is probably adequate.

When is factor analysis inappropriate when sample size is below 50?

There is universal agreement that factor analysis is inappropriate when sample size is below 50. Bartlett’s test is another indication of the strength of the relationship among variables. This tests the null hypothesis that the correlation matrix is an identity matrix.
