PSYC 612

Psychometric Theory, Assessment, Appraisal, and Applications

• SPSS Activities: The BIGFILE

• SPSS review

• Norms lab on August 30:  Most of this exercise will be done during lab.  Hard copies will be brought to class so you do not need to print it.  You will need to be introduced to the content of the data file before you can proceed.  Some of the questions pertain to creating an expectancy table, which we have yet to discuss.  However, the purpose of this lab is to refresh your memory about descriptive statistics and be sure you can manipulate variables in SPSS using the RECODE, COMPUTE, SPLIT FILE and other options.
