Answer 1

Answer:

mean median mode

Explanation:

mean

to find mean

no of observation

total no of observation

x=30+35+40+50+15+30+25+55+30+32+25+43+45

13

455

13

x=35

median

to find median

write the data in assending order

15,25,25,30,30,30,32,35,40,43,45,50,55,

13 (odd)

value of n+1 by 2th

13 + 1 by 2

14 divided by 2

=7

7th score

32 is median

mode

the score repeats maximum times

so

30 is mode
