Question

Yao throws a die twenty times and records his observation as represented 4,2,1,6,5,3,5,6,1,2,1,5,5,6,3,4,3,5,1,5 construct a frequency distribution table and find the mode,median,and mean of yao's observation

Answer 1

step by step

Mean=

number of observations

sum of observations

⇒ Mean=

15

1+1+1+2+2+2+3+3+4+4+5+5+6+6

=

15

47

=3.13

Now, total number of observations =15, which is odd.

∴ Median =8

th

term =3

Now, the observation 2 occurs the most i.e., 4 times

∴ Mode =2

Hence, Mean =3.13, Median =3 and Mode=2$$.

Hope it's help you if I did then please mark me as brainlist
