Answer 2

Explanation:

Mean = $\dfrac{\textrm{Sum of numbers }}{\textrm{total number}}$

Median,

First arrange the given data in ascending or descending order then start eliminating the numbers from last to first.

Mode = the most repeated numbers.

1) 19,25,23,20,20,15,10,16,25,24

Mean =   $\frac{19+25+23+20+20+15+10+16+25+24}{10}$ = 19.7

Median

First arrange the numbers,

10,15,16,19,20,20,23,24,25,25 = $\frac{40}{2}$ = 20

Mode = The most repeated term

so,

20 and 25 are the mode

3) 13,16,12,14,19,12,14,13,14

Mean = $\frac{13+16+12+14+19+12+14+13+14}{9\\}$ = 14.1

Median = 12,12,13,13,14,14,14,16,19 = 14

Mode = 14
