Mark statistics frequency

Marks with equal weight 2,1,3,2,2,3,1,3,1,1,2,4,2,2,3,1,1,2,1,3
specify:

1) arithmetic mean
2) absolute and relative frequency
3) mode and median
4) create a chart

Final Answer:

m =  2
m₁ =  2
m₂ =  2

Step-by-step explanation:

$$\begin{gathered} 2,1,3,2,2,3,1,3,1,1,2,4,2,2,3,1,1,2,1,3 \\ 1,1,1,1,1,1,1,2,2,2,2,2,2,2,3,3,3,3,3,4 \\ s=2+1+3+2+2+3+1+3+1+1+2+4+2+2+3+1+1+2+1+3=40 \\ n=20 \\ m=\frac{s}{n}=\frac{40}{20}=2 \end{gathered}$$

$m_1=2$

$m_2=2$
