To find the mean, add up all the numbers in the dataset and divide by the total number of values.
Mean:
10 + 17 + 11 + 24 + 12 + 7 + 15 + 17 + 20 + 5 + 11 + 21 + 16 + 17 = 188
Mean = 188 / 14 = 13.43 (rounded to two decimal places)
To find the median, first put the numbers in numerical order:
5, 7, 10, 11, 11, 12, 15, 16, 17, 17, 17, 20, 21, 24
Since there are an even number of values (14), the median is the average of the two middle numbers (12 and 15):
Median = (12 + 15) / 2 = 13.5
To find the mode, identify the number that appears most frequently in the dataset:
Mode: 17 (appears 3 times)
