What are the mean and median of the following dataset?
5, 7, 11, 11, 6
To find the mean, you add up all the numbers and divide by the total number of numbers:
(5 + 7 + 11 + 11 + 6) ÷ 5 = 8
The mean of the dataset is 8.
To find the median, you need to put the numbers in order from least to greatest:
5, 6, 7, 11, 11
The median is the middle number. In this case, it's 7 because it's the third number in the dataset.
The median of the dataset is 7.
