Stuff on group and ungrouped data
In the following picture below we did a little test or exercise on how to find the mean of grouped data. Any way here's the steps I used to find the mean of the grouped data.
1. Stat/ Enter
2.in the L1 data set put in the number of days of exercise per week
3.in the L2 data set put in number of people
4.Stat /Calc/1: var stat/ Enter
5. 2nd 1 / , / 2nd 2
The pic below explains group and ungrouped data.
As for the pic or clip below Mr.Max showed that the total of the second column is the N.For all of you who don't know what N is, N is how many pieces of data there are.
