To find the mean of the data set, you need to add up all the numbers and then divide by the total number of values:
Mean = (15 + 16 + 21 + 23 + 25 + 25 + 25 + 29) / 8 = 21.5
To find the median, you need to find the middle value of the set, which is the value that is exactly halfway into the set when it is ordered from lowest to highest. In this case, the data set has an even number of values, so the median is the average of the two middle values:
Median = (23 + 25) / 2 = 24
To find the mode, you need to find the value that appears most frequently in the set. In this case, the number 25 appears three times, so it is the mode:
Mode = 25
Therefore, the mean, median, and mode of the data set are 21.5, 24, and 25, respectively.
find the mean median and mode of the data set.
15,16,21,23,25,25,25,29
