Question

he sample is a subset of the population and we derive the properties of the population like mean, median from the sample.

Answer 1

Given statement is true.

Explanation:

• Sample is a subset of population and with the help of that we can derive the properties of the population like mean, median from the sample.
• A population is the set of the elements from the set of a data.
• It contains all the members of a group.
• Whereas, a Sample contains one or more elements from the population.
• Elements of sample are subset of the elements of the population.
• Example:

       1. Consider a population, contains the elements {1, 2, 3, 4, 5, 6} and a

          sample is taken from the population, which contains {1, 2} as its

          elements. Here, the sample is a subset of the population.

       2. Real life example:

           To check whether the rice has cooked properly or not, we will take

           1 or 2 grains and check. We will not take all whole grains and check.

           Here, all grains are population and the grains which we took to

           check whether the rice is properly cooked or not are sample.
