To test their memory of the film, a sample of thirteen individuals who had watched Cool Hand Luke were asked to recount the number eggs involved in the wager. The following scores reflect their responses. Determine the typical number of eggs remembered in the movie using the mean and the median.

40, 30, 50, 40, 50, 40, 50, 60, 80, 50, 60, 30, 70.

QUESTION 1:

1. Make a Frequency Distribution Table. Add columns for fX, cf,and c%

2. Calculate the Mean (4 marks).

3. Calculate the median by finding the middle score

4. Using the frequency distribution table, expand the first column so that each row represents a single case (or participant)

1. Calculate the variance and standard deviation of the scores using the definitional formulas (5 marks).
