### About Mean Median Mode:

To find the mean, sum the numbers and divide by the number of numbers in the group. To find the median, we arrange the numbers from least to greatest, then choose the middle number (odd number of numbers) or the average of the two middle numbers (even number of numbers). The mode is the number(s) that occurs most often.
