*Please refer toSPSS Commandsfor tips on analyzing data.

1. Factor Analysis

A researcher is examining factors that predict language development among first grade students. The researcher believes that some of the variables may be correlated and would like to run factor analysis to reduce multicollinearity. The researcher would like to use factor analysis to examine the following variables from thedata file:

• reversal (syllable reversal),


• delete onset,


• judgment of tone,


• learn word (morpheme learning),


• odd word (pick up the odd word in four choices),


• circle word (select the correct "root" for the word),


• fill in word (fill in a word in a sentence),

Conduct Factor Analysis with SPSS. Write a report describing and interpreting the results of your factor analysis. Include relevant tables.

2) Compare statistical tests that were presented in RMS608 and RMS618

Complete the following table, which includes statistical tests from RMS608 and RMS618:
