Question

which one of the following measures of dispersion is more useful in case of open end distribution​

Answer 1

Answer:

quartile deviation

The quartile deviation is easy to compute and understand. It is a better measure of dispersion than range because it makes use of 50% of the data. It is not affected at all by extreme observations. It can be computed from the frequency distribution with open end classes.
