Question

following are the observation of throwing a dice 15 times 5,3,4,1,6,2,2,4,3,2,1,5,1,6,2. find the mean,mode and median of this data.​

Answer 1

Step-by-step explanation:

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$$.
