Time | Mean, Median and Mode | ping pong activity

Mean adds all the numbers up and divides it by the amount of numbers. For example: 1+2+3+4+5= 15, 15 ÷ 5 = 3, the mean is 3.

Median organizes the numbers from least to greatest and selects the number in the middle. If there are more than one middle number, add them and divide by 2. For example: 10=1+2+3+4+10= 30, 30 ÷ 5 = 6, the mean is 6.

Mode organizes the numbers from least to greatest and determines the most popular number (the number that appears the most). For example 3 3 4 5. The most popular number is 3.

This investigation shows how long it takes for a person to complete a physical activity. Once the person has completed the activity, they convert their time, find their mean, median and mode. The graph below shows the fastest and the slowest time taken to complete the activity.

LI: to investigate units of time.
