The mean is the average of the date It is surprisingly easy to calculate: add up all the data, then divide by how many data points there are.

Becker's data added up is 28. Kayla's data added up is 30. The total amount is 58.

The amount of data points are 20.

58/20 = 2.9

The mean number of games chess team members play per day is 2.9

Becker = 5,2,4,1,1,4,5,3,2,1

= (5 + 2 + 4 + 1 + 1 + 4 + 5 + 3 + 2 + 1) / 10

Mean average = 28 / 10

= 2.8

Kayla = 2,3,1,1,4,1,5,3,5,5

= (2 + 3 + 1 + 1 + 4 + 1 + 5 + 3 + 5 + 5) / 10

= 30 / 10

= 3

Total = Becker + Kayla

= 2.8 + 3

= 5.8

Mean average = 5.8 / 2

= 2.9

Therefore, the mean number of games chess team members play per day is 2.9
