Sample parameter, Population parameter, Sample statistic, Population mean

Solution:

A numerical value used as a summary measure for a sample, such as a sample mean, is known as a sample statistic.

For example -

Let us say we have to find how much a person earns in India. The population is every Indian. Due to time and the amount spent, you cannot ask each and every person.

So consider 1000 people in random. So these 1000 people become our sample data.

A sample statistic is a piece of information that is obtained from a fraction of the population.

Therefore, a numerical value used as a summary measure for a sample, such as sample mean, is known as a sample statistic.
