Question

A method of dispersion that gives us an overall picture of the gap between all the data within a data set is

A. Range.
B. Inter-quartile range (Q3 – Q1).
C. Mean.
D. Standard deviation.
E. coefficient of correlation

Answer 1

The correct answer is letter "D": Standard deviation.

Step-by-step explanation:

Standard deviation is a measure used to count the deviation or dispersion of a group of numeric data. In Business, the standard deviation is a measure applied to the annual rate of return of an investment to measure the investment's volatility. Every time a stock or a mutual fund is purchased their expected return is weighted against their inherent risk. The past gain or losses of investment is easy to look up but gauging is more complex.
