Question

find the median of variates 5,7,8,11,13,17 with frequencies 3,7,7,13,10 respectively also find the mode of data​

Answer 1

Answer:

11

Step-by-step explanation:

Given that variants 5,7,8,11,13,17 with frequencies 3,7,7,12,13,10 respectively.

x f Cumulative frequency

5 3 3

7 7 10=3+7

8 7 17=10+7

11 12 29=17+12

13 13 42=29+13

17 10 52=42+10

∑f=N=52

N=52 -even

2

N

=

2

52

=26

th

term

the cumulative frequency just gleater than

2

N

value is 29, and the value of x corresponding to 29 is 11.

therefore median is 11.
