Question

The graph shows a player’s monthly home run total in two seasons.

Answer 1

a) standard deviation of the scores of the monthly home run totals in the player’s rookie season will be 1.29

b) The standard deviation of the scores of the monthly home run totals in this season will be 2.738

What is standard deviation?

Standard deviation is defined as the amount of variation or the deviation of the numbers from each other.

a)The standard deviation of the scores of the monthly home run totals in the player’s rookie season:-

The data from the graph will be

1,0,6,2,0,2

Standard deviation is calculated as:-

$\sigma = \dfrac{\sqrt{\sum(x-\mu)^2}}{N}}$

$\mu = \dfrac{1+0+6+2+0+3}{6}=2$

Putting the values we get

$\sigma = \dfrac{\sqrt{(1-2)^2+(0-2)^2+(2-2)^2+(0-2)^2+(3-2)^2}}{6}}=1.29$

Hence standard deviation is 1.29

b)The standard deviation of the scores of the monthly home run totals in this season

The data from the graph will be

4,6,4,8,7,13

Standard deviation is calculated as:-

$\sigma = \dfrac{\sqrt{\sum(x-\mu)^2}}{N}}$

$\mu = \dfrac{4+6+4+8+7+13}{6}=7$

Putting the values we get

$\sigma = \dfrac{\sqrt{(4-7)^2+(6-7)^2+(4-7)^2+(8-7)^2+(7-7)^2+(7-13)^2}}{6}}=2.738$

Hence standard deviation is 2.738
