Question

find the median of the following Data 25,19,17,24,31,26,40,42​

Answer 1

Answer:

25,19,17,24,23,29,31,40,19,20,22,26,17,35,21

first of all arrange the marks in ascending order

17,17,19,19,20,21,22,23,24,25,26,29,31,35,40

Here observe that no of student off i.e. n=15

So median is

2

n+1

th term i.e. middle term

median =

2

n+1

th term

=

2

15+1

th term

=

2

16

th term

=8

th

term

Median =23

Answer 2

Step-by-step explanation:

Given that the marks of 15 students in an examination are

25,19,17,24,23,29,31,40,19,20,22,26,17,35,21

first of all arrange the marks in ascending order

17,17,19,19,20,21,22,23,24,25,26,29,31,35,40

Here observe that no of student off i.e. n=15

So median is

2

n+1

th term i.e. middle term

median =

2

n+1

th term

=

2

15+1

th term

=

2

16

th term

=8

th

term

Median =23

∴ median scole student marks =23
