Range of Value:

The range of value refers to the difference between the highest and lowest values in a set of data. It is a measure of dispersion that helps to understand how spread out the data is. The range can be calculated for any set of data, regardless of whether it is continuous or discrete.

A Point Estimate:

A point estimate is a single value that is used to estimate an unknown parameter of a population. It is based on a sample of data and is used to make inferences about the population. A point estimate is typically the mean or median of the sample data.

An Interval Estimate:

An interval estimate is a range of values that is used to estimate an unknown parameter of a population. It is based on a sample of data and is used to make inferences about the population. An interval estimate is typically represented as a confidence interval, which gives a range of values within which the true population parameter is expected to lie.

Both:

A range of value is an interval estimate because it represents a range of values that the true population parameter is expected to lie within. At the same time, it can also be considered a point estimate because it provides a single value that represents the spread of the data.

Conclusion:

In conclusion, a range of value can be both an interval estimate and a point estimate, depending on how it is used. It is a useful measure of dispersion that helps to understand how spread out the data is.
