The given data are :


49,54,37,48,42,41,36,45,47

At first, make the data in order from the least to the greatest


36,37,41,42,45,47,48,49,54

Mean is the average of the data

Mean = (sum of the data)/(number of the data)

Sum of the data =


36+37+41+42+45+47+48+49+54=399

The number of the data = 9

So,


\text{Mean}=(399)/(9)=44(1)/(3)=44.33

Median is the number which is in the middle of the data

We have 9 data

So, the median is the number (9+1)/2 = 10/2 = 5

So,


\text{Median}=45

Mode is the data which is repeated more than the others

So, when we looking to the data, each number appeared one time

So,

There is no mode
