Question

Please do the above questions ​

Answer 1

Answer:

1) i) Mode

ii) Range

iii) Mode

iv) Median

v) Bar Graph

2) Mode = observation which occurs the most number of times

Hence, Mode = 23

Median = the middle number after arranging the numbers in ascending order.

Ascending order of numbers is 19,20,20,21,23,23,23,23,24,24,25

Median = (23 + 23)/2 = 23

Yes, both are the same

3) i) Range = 9 - 1 = 8

ii) Range = 12.5 - 1.4 = 11.1

4) Mean = sum of all observations / no of observations

$Mean = \frac{20 + 25 + 27 + 40 + 38 + 43 + 18}{7}$

Mean = 30
