Question

Combine Felix's and Tyler's data. What is the mean of the combined data? Include your calculations as part of your answer. (Hint: Use a shortcut to find the answer.)

Answer 1

Answer: 31.82

Explanation:

Combine the sum of Felix's and Tyler's values together and divide by the total number of values (100).

Sum of Felix's values: 469

Sum of Tyler's values: 2,713

2,713 + 469 = 3,182

3,182 / 100 = 31.82

Mean: 31.82

I did the sums on a separate sheet of paper. I used this to create a shortcut to find the answer.

Hope this helps!

Answer 2

Answer: 31.7

Explanation:

Felix mean= 9.4

Felix median= 7

Tyler's mean= 54

Tyler's median = 66

The mean of combined data will be the mean of Felix and the mean of Tyler. This will be:

= (9.4 + 54)/2

= 63.4/2

= 31.7
