How do I find the mean and median of 3, 7, 7, 2, 9?
How to find the mean and median of 3, 7, 7, 2, 9: sort the numbers to find the middle value (median 7), then add them and divide by 5 (mean 28 ÷ 5 = 5.6).
Step-by-step explanation
- To find the mean and median of the dataset 3, 7, 7, 2, and 9, let's start by visualizing the raw numbers.
- To find the median, we first sort the data in ascending order: 2, 3, 7, 7, 9. The median is the middle value, 7.
- To find the mean, we sum all the numbers together and divide by the total count of numbers.
- Finally, dividing 28 by 5 gives us a mean of 5.6.
