One sample has n = 4 scores and m = 10. a second sample has n = 8 scores and m = 4. if the two samples are combined, what is the mean for the combined sample?

Answers

Based on the above, The mean of the combined sample is 5.53.

What is the mean about?

The given parameters of the question were:

The number of the first sample = 4

The mean of the first sample = 10

The number of the second sample = 8

The mean of the second sample = 4

Therefore, To find:

The combined mean of the two samples

The total sample number = 4 + 8 = 13

The sum of the first sample = 4 x 20 = 40

The sum of the second sample = 8 x 4 = 32

The sum of the two samples = 40 + 32= 72

The mean of the combined samples;

72/13 = 5.53

Therefore, Based on the above, The mean of the combined sample is 5.53.
