Step-by-step explanation:

mean = 12.7

add all and divide by no.of terms

mode= 13

highest occuring no.

median= idk

Answer 2

Answer:

1.69,14,13

Step-by-step explanation:

QN.

find mean, median, and mode of the following numbers;

12,13,14,15,10,11,13,13,14,12

F x fx

2 12 24

3 13 39

2 14 28

1 15 15

1 10 10

1 11 11

N=75 Σfx= 127

 

now,

mean =Σ fx/n

=127/75

=1.69

And,

median= (n + 1)/2 th  

= (75+1/2) th  

(76/2) th  

38th item  

median=14

             again,

                      mode= highest repeating frequency  

           so, it is 13
