Which of the following measures of spread are based on the mean?
A. Variance and C. Standard deviation
Answer:
Variance and standard deviation
Step-by-step explanation:
The range is the difference between maximum and minimum values in the data set.
Thus range in no way depends on mean
Interquartile range is the difference between Q1 and Q3 i.e. I quartile and III quartile. This has nothing to do with the mean value.
But Std deviation and variance depend on mean
Because variance is the average of sum of squares of each entry from the mean
And std deviation is square root of variance
Thus both depend on the mean
