Does a sample reflect the population?

A sample should represent the population as a whole and not reflect any bias toward a specific attribute. There are several sampling techniques used by researchers and statisticians, each with its own benefits and drawbacks.

What are the characteristics of sample and population?

A population is the entire group that you want to draw conclusions about. A sample is the specific group that you will collect data from. The size of the sample is always less than the total size of the population. In research, a population doesn't always refer to people.

What is also known as a representative sample?

The correct solution is "Non-Probability Sampling".

What are the defining characteristics of a sample?

A sample is a smaller, manageable version of a larger group. It is a subset containing the characteristics of a larger population. Samples are used in statistical testing when population sizes are too large for the test to include all possible members or observations.
