Class 10>>Maths>>Statistics>>Median of Grouped Data>>A die was thrown 15 times and the outcom

Rearranging the data into ascending order, we get 

1,1,1,2,2,2,2,3,3,4,4,5,5,6,6

We know that,

Mean=number of observationssum of observations

⇒ Mean=151+1+1+2+2+2+3+3+4+4+5+5+6+6

=1547=3.13

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

∴ Median =8th term =3

 

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

∴  Mode =2

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

Step-by-step explanation:

I hope it will help you.
