Re:
July Coupon Promotion Results – Specific Descriptive Statistics
Coupon Promotion Results
As a follow up to my previous memorandum, I have prepared specific descriptive statistics regarding the results of the previous coupon promotion period throughout the month of July.
These descriptive statistics such as the relationship between net sales and descriptive statistics on net sales by various classifications of customers, as well as the descriptive statistics concerning the relationship between age and net sales can help us further understand our target audience and ultimately boost total sales for Pelican Department
Stores. By identifying our mean, median and mode regarding each variable (marital status, type of customer, gender and age), we can further understand the relationships between our variables. Descriptive Statistics on Net Sales:
