Answer: The mean of the following data is 51.333
The median of the following data is 80.
Step-by-step explanation: First, we have to find the mean of the following data and the formula to find mean is :
Mean= sum of terms/ number of terms
As the number of terms are 9.
Hence, we will put the values i.e.,
Mean= 6+18+9+95+80+76+40+65+73/9
Mean= 462/9=51.333
Now, we will find median of the following data. In this suitable question, the total number of observations are 9. And 9 is an odd number. So, the formula to find median will be:
Median= ((n+1)/2)^th observation
Value of n is 9. So, on putting the value of n ,we get:
Median= ((9+1/2))^th observation
Median= 5^th observation
So, according to the question the 5th term is 80. Hence, our median is 80.
