Answer:
a) mean = 0.87
b) median = 0.71
c) mid range = 1
d)In given data there is not a number that occurs more than any other, it means there is no mode for the data. no repetition values are there in data.
Step-by-step explanation:
Given data :-
a) mean
1.43 0.52 0.61 0.55 0.48 1.53 0.41 0.96 1.59 0.71 0.81
The number of observations n = 11
[tex]mean = \frac{sum of the observations}{number of observations}[/tex]
[tex]mean = \frac{ 1.43+ 0.52+ 0.61+ 0.55+ 0.48+ 1.53+ 0.41+ 0.96 +1.59+ 0.71 +0.81}{11}[/tex]
mean = 0.87
b) The median is obtained by first arranging the data in ascending or descending order
0.41 ,0.48 ,0.52 ,0.55, 0.61, 0.71, 0.81, 0.96, 1.43, 1.53, 1.59
median = [tex](\frac{n+1}{2}) ^{th}[/tex] = 6^th term = 0.71
c) midrange:-
[tex]midrange = \frac{maximum value + minimum value}{2}[/tex]
mid range = [tex]\frac{1.59+0.41}{2} = 1[/tex]
d) mode:-
In given data there is not a number that occurs more than any other, it means there is no mode for the data.
