Here is a list of scores on the Traditionalism Index for the ANES unique group of
respondents who simultaneously rated Christian Fundamentalists and Atheists
at 100 on the Feeling Thermometer:
7, 10, 5, 6, 5, 8, 5, 12, 4, 11, 11, 9, 10, 13, 8, 8, 7
Use these raw data to the find the mean, median, mode, variance, and standard
deviation.
Solution:- Given data 7,10,5,6,5,8,5,12,4,11,11,9,10,13,8,8,7
Mean :- sum of terms /number of terms
= 139/17
= 8.1765
Median:-
Explanation
The median is the middle number in a sorted list of numbers. So, to find the median, we need to place the numbers in value order and find the middle number.
Ordering the data from least to greatest, we get:
4 5 5 5 6 7 7 8 8 8 9 10 10 11 11 12 13
So, the median is 8 .
Mode :-
Explanation
The mode of a set of data is the value in the set that occurs most often.
Ordering the data from least to greatest, we get:
4 5 5 5 6 7 7 8 8 8 9 10 10 11 11 12 13
Since both 5 and 8 occur 3 times, the modes are 5 and 8 ( this data set is bimodal).
Variance :-
Standard deviation:-
