The questionnaire chosen was the Blake & Mouton Managerial Grid as it assesses leadership behavior. The numeric raw data results of the 18 question study are as follows:

Complete the following in a single MS Word or Excel document:
- Calculate the mean, median, mode, variance, and standard deviation for the numeric data.
- Construct a histogram, pie, or Stem-Leaf Display chart encompassing the mean leadership scores for both male and female managers. Use an online interactive program to formulate your histogram, pie charts, or Stem-Leaf Display.
- Construct a histogram for median score values for male managers and female managers with respect to management style.
- Analyze the data and present preliminary conclusions based on answers to questions #2 and #3 with respect to the leadership style differences between male and female managers.
- Offer a brief 5-point summary of the training program you might use to strengthen the leadership deficiencies found in either or both the male and female manager leadership style.
