find the mean median and mode for the data set 15 16, 21,23, 25,25, 25,39

Answer 1

Mean: To find the mean, add up all the numbers in the data set and then divide by the total number of numbers.
Mean = (15 + 16 + 21 + 23 + 25 + 25 + 25 + 39) / 8 = 189 / 8 = 23.625

Median: To find the median, first arrange the numbers in ascending order.
15, 16, 21, 23, 25, 25, 25, 39
Since there are 8 numbers in the data set, the median will be the average of the middle two numbers.
Median = (23 + 25) / 2 = 48 / 2 = 24

Mode: The mode is the number that appears most frequently in the data set.
In this case, the mode is 25 because it appears three times, more than any other number in the data set.
