When looking at box scores of your favourite NHL, NBA, Champions League or F1 racing team, it is important to understand what kind of descriptors are used to make sense of the big set of numbers that are collected. For example, it might be important to know how many times a point guard loses the ball in a basketball match or how fast an F1 driver drives around a certain track. But how can we compare different point guards or F1 drivers to know which one is best and gets the contract or a place in the starting five. This is when mean, median and mode come in handy.

Let’s learn the theory about **Statistics: Mean, median and mode**

Exercises:

1. Scores in a math test were 16, 22, 19, 22, 20, 15, 18, 17 and 24.

- Calculate the mode
- Calculate the median
- Calculate the mean

2. Grade in all the math test throughout the academic year for John were 8-, 8+, 7½, 8+, 7, 8½ and 9

- Calculate the mode
- Calculate the median
- Calculate the mean
