Question

1. The scores in mathematics test (out of 25) of 15 students is as follows:
19, 25, 23, 20,9, 20, 15, 10, 5, 16, 25, 20, 24, 12, 20
find the mode and median of the data? Are they same?​

Answer 1

Step-by-step explanation:

Mode

No. which comes most of the time i.e 20

Median

The middle most observation

First we have to arrange the numbers in ascending order : 5,9,10,12,15,16,19,20,20,20,20,23,24,25,25

The number of observation is odd therefore the middle most observation i.e 20 is the median.

Answer 2

putting nubers in series

5, 9, 10, 12, 15, 16, 19, 20, 20, 20, 20, 23, 24, 25, 25

so, mode = no. of most frequency = 20

mode is 20 as it is coming 4 times in the series.

median = 20 as the series contain odd numbers and the middle no. is 20.

YES, THE MODE AND MEDIAN ARE SAME
