To find the mean, we add up all the numbers and divide by the total number of numbers:
Mean = (15 + 16 + 21 + 23 + 25 + 25 + 25 + 39) / 8 = 23.6
To find the median, we need to find the middle number. Since there are 8 numbers in the set, we take the average of the 4th and 5th numbers:
Median = (23 + 25) / 2 = 24
To find the mode, we look for the number that appears most frequently. In this case, 25 appears three times, so the mode is 25.
Therefore, the answer is D. mean = 23.6, median = 24, mode = 25.
Multiple Choice
