INSTRUCTIONS TO CANDIDATES

Q1. Determine how many cases of familiarity with Kohl’s have missing values.

Q2. How are missing values coded in the above variable (i.e., familiarity with Kohl’s)?

Q3. Replace the missing values of familiarity with Kohl’s with the mean value and run a frequency distribution (Hint: need to get the mean value of familiarity with Kohl’s). What is the standard deviation of this new variable? What is the mode of this new variable?

Q4. Recode the demographic variable of “marital status”: 1 = 1; 2 or 3 = 2 and run a frequency distribution. What is the valid percentage of people who are married?

Q5. Run a frequency distribution for the overall familiarity score (sum the familiarity with each of the 10 department stores) with all accompanying descriptive statistics. What are the mean, median, and variance of the overall familiarity score? (Hint: create a new variable “overall familiarity score”)

Q6. Recode the overall familiarity score as follows: 32 or less = 1; 33 to 37 = 2; 38 to 43 = 3; 44 to 60 = 4 and run a frequency distribution. What is the valid percentage of the overall familiarity score from 33 to 37? What is the cumulative percentage of the overall familiarity which is coded as “3”?
