Question

The score in mathematics test of 15 students is as
follows:19,25,23,20,9,20,15,10,5,16,25,20,24,12,20
Find the median and mode

Answer 1

Step-by-step explanation:

Given 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

Mode means which observation is most frequently occurred

Here observe that 20 is most frequently occurred so mode is 20. __(1)

first of all average the data in ascending order

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

Here observe that no of observations (n)=15

So median is

2

N+1

th

term

median =

2

15+1

th

term

=

2

16

th

term =8

th

term

median =20 __(2)

from (1) & (2)

mode = median

(Both are same

Answer 2

Answer:

mode is 20

median is 20

bro this is the answer bro
