The given data are :
[tex]49,54,37,48,42,41,36,45,47[/tex]At first, make the data in order from the least to the greatest
[tex]36,37,41,42,45,47,48,49,54[/tex]Mean is the average of the data
Mean = (sum of the data)/(number of the data)
Sum of the data =
[tex]36+37+41+42+45+47+48+49+54=399[/tex]The number of the data = 9
So,
[tex]\text{Mean}=\frac{399}{9}=44\frac{1}{3}=44.33[/tex]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,
[tex]\text{Median}=45[/tex]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
