Use all the variables in the dataset
Create a correlation matrix of all the variables
Which pairs are correlated?
Run factor Analysis using all the variables
Obtain the scree plot & the Eigenvalue
Based on the scree plot, how many factors are optimal?
Under the model launch test the number of factors that is optimal
1. Type 1 in the number of factors. Leave all the default settings, Select go. Report the estimates for the significant test. Is one factor sufficient?
2. Repeat this step- click the arrow next to the Model Launch and type two in the number of factors box. Based on the significance test, are two factors sufficient?
If so, what at the variables loading on Factor 1 and Factor 2?
What do you think these variables describe?
Using your correlation matrix, describe the correlation between the variables loading for each factor.
Which variable is the least important in explaining the variance and factors in this dataset?
