Question 1 Report

The number of goals scored by a football team in 20 matches is shown below:

$\begin{array}{cc} No. of goals & 0 & 1 & 2 & 3 & 4 & 5 \\ No. of matches & 3 & 5 & 7 & 3 & 1 & 0 \end{array}$

What are the values of the mean and the mode respectively?

(1.75, 5)

(1.75, 2)

(1.75, 1)

(65, 74)

Answer Details

$\begin{array}{cc} x & f & f x \\ 0 & 3 & 0 \\ 1 & 5 & 5 \\ 2 & 7 & 14 \\ 3 & 4 & 12 \\ 4 & 1 & 4 \\ 5 & 0 & 0 \end{array}$
$\sum f$ = 20
$\sum f x$ = 35
Mean = $\frac{\sum f x}{\sum f}$
= $\frac{35}{20}$
= $\frac{7}{4}$
= 1.75
Mode = 2
= 1.75, 2
