Program Evaluation

When NOT to Evaluate:

(6 reasons)

Evaluation would produce trivial information
Evaluation results will not be used 
Evaluation cannot yield useful, valid information

Evaluation is premature for the stage of the program – do developmental evaluation instead

Propriety of evaluation is doubtful

  • An evaluability assessment suggests that an evaluation is inappropriate at this time

Which measurement scale is the best match to the real number scale?
Ratio
This measurement scale has a true zero point
ratio data

arithmetic average of the scores in a distribution computed by summing the scores and dividing by the number of scores.

Mean
most frequent score
Mode
the middle score in a distribution where the scores have been arranged in order low to high
Median

True/False

Median gives a better indication of what the typical score is if there are some deviant scores in the distribution- unusually high or low score

True

difference between highest and lowest score; too unstable
