Question

The table shows the number of yards a football player runs in each quarter of a game. Find the mean number of yards the player runs per quarter.

Answer 1

Yards run in each quarter:

Quarter 1: -2

Quarter 2: 14

Quarter 3: -18

Quarter 4: -6

Total number of quarters = 4

Sum of yards = (-2) + 14 + (-18) + (-6)

⇒ Sum of yards = -12

Mean number of yards run per quarter = $\frac{\text{Sum of yards}}{\text{Number of quarters}}$

⇒ Mean number of yards run per quarter = $\frac{-12}{4}$

⇒ Mean number of yards run per quarter = -3

Hence, mean number of yards run per quarter is -3

Answer 2

Answer: -3 per quarter.

Step-by-step explanation:

The formula we use to find the mean is given by:-

$\text{Mean}=\dfrac{\text{Sum of observations}}{\text{Number of observations}$

In the given table , we have the number of yards a football player runs in each quarter of a game.

$\text{Mean}=\dfrac{-2+14-18-6}{4}\\\\\Rightarrow\ \text{Mean}=\dfrac{-12}{4}=-3$

Then , the mean number of yards the player runs per quarter is -3  runs per quarter.
