Valentine’s Day Stats with Minitab Graphs (and a Special Valentine’s Trick to Impress Your Favorite Quality Engineer)
How will you celebrate Valentine’s Day this year? Maybe it will involve buying a gift for your sweetie, or perhaps a special dinner out. According to the National Retail Federation’s (NRF) 2012 Valentine’s Day Consumer Intentions and Actions Survey, the average person will spend $126.03 to celebrate this year's holiday!
In Minitab, I created a Time Series Plot (Graph > Time Series Plot > Simple) to display the NRF’s data for average Valentine’s Day spending (per person) since 2003.
You can see the average spending per person has steadily risen over the years—and this year's expected spending ($126.03) is higher than last year ($116.21) by 8.5%.
Here's how I set up the data in my Minitab worksheet:
The NRF survey also asked men and women what types of gifts they planned on giving this year. The clustered Minitab Bar Chart (Graph > Bar Chart) below displays the percent of men and women who plan on giving the following gifts on February 14th: candy, flowers, jewelry, greeting cards, an evening out, clothing, and a gift card/certificate.
And in terms of how much money the average person will spend on different groups of people this Valentine's Day, the following Minitab Pie Chart (Graph > Pie Chart) categorizes anticipated spending by the type of person being bought for, provided the buyer answered "yes" to purchasing for the category of person (significant other/spouse, other family members, friends, children’s classmates/teachers, co-workers, pets, and other).:
