Question

find mean, mode of 45,45,54,45,64,54

Answer 1

Hi !

Mode = Frequently occurring no:
45,45,54,45,64,54
In these no:s 45 occurs two times .
Hence ,
Mode = 45
--------------------------------------------------------

Total no: of observations = T = 6
Sum of observations = S =45 + 45 + 54 + 45 + 64 + 54 = 307

Mean = S/T
=307/6
= 51.16
= 52 (approx.)

Answer 2

mean=sum of observations/no.of observations.45+45+54+45+54+60/6=303/6=5.5is the mean and mode is 45 because it was repeating more times.
