I have been given data on 45 employees regarding their performance before and after a training programme.How do I check whether the efficiency of the workers has improved or not?and whether such improvement can be attributed to training?

You have "paired" data. YOu want to test if the difference between before and after is significant. You should be able to find a "paired t-test" in most statistics books.

I have been asked to use simple methods for the clculation and more emphasis being on the theory surroundng data analysis.Also what do I do about workers who have been absent?Do I take difference in values as zero?
