When finding out

When finding out the number of minor children in 18 households, these results were obtained:
0, 2, 2, 2, 1, 1, 1, 1, 1, 0, 3, 2, 1, 1, 0, 2, 3, 2 .

a. Arrange the values of the variable by size.
b. Construct a frequency distribution table and calculate relative frequencies and relative
frequencies in percentages.
c. Represent graphically.
d. Calculate the arithmetic mean, median, mode

Final Answer:

a =  1.3889
m =  1
m₂ =  1

Step-by-step explanation:

$$\begin{gathered} \{0,2,2,2,1,1,1,1,1,0,3,2,1,1,0,2,3,2\} \\ \{0,0,0,1,1,1,1,1,1,1,2,2,2,2,2,2,3,3\} \\ n=18 \\ a=\frac{2+2+2+1+1+1+1+1+3+2+1+1++2+3+2}{n}=\frac{2+2+2+1+1+1+1+1+3+2+1+1++2+3+2}{18}=\frac{25}{18}=1\frac{7}{18}=1.3889 \end{gathered}$$

$m=1$

$m_2=1$
