Question

the scores in mathematics test of 15 students is as follows 9,25,23,20,9,20,15,10,5,16,25,20,24,12,20 find the mean, median and mode of the following data​

Answer 1

Step-by-step explanation:

mean=9+24+23+20+9+20+15+10+5+16+25+20+24+12+20/15

=16.8

median=ascending order of scores

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

n=15

median=20+20/2

= 40/2

=20

mode=mostly repeated value

=20
