To find the mean, add up all the numbers in the dataset and then divide it by the total number of values:
10 + 17 + 11 + 24 + 12 + 7 + 15 + 17 + 20 + 5 + 11 + 21 + 16 + 17 = 198
There are 14 numbers in the dataset, so the mean is 198/14 = 14.14 (rounded to two decimal places).
To find the median, first arrange the numbers in ascending order:
5, 7, 10, 11, 11, 12, 15, 16, 17, 17, 17, 20, 21, 24
Since there are 14 numbers, the median is the average of the 7th and 8th numbers. Therefore, the median is (12 + 15)/2 = 13.5.
To find the mode, determine which number appears most frequently in the dataset. In this case, the number 17 appears 3 times, which is the highest frequency, so the mode is 17.
