Bev Johnson is analyzing sales during her first 16 weeks in business. The weekly sales data are in thousands of dollars. Read down the columns, beginning with the left column, for successive weeks of the year.
Construct a table that shows each weekly sales amount. Then go through the data and place a tally mark ( | ) next to each corresponding value to create a frequency distribution table.
The frequency distribution shows that the most common weekly sales amount was $6100, although there were two weeks with each of the following in sales: $4900, $5200, and $7200.
