In Non-probability samples – specific elements from the population are selected in a non-random manner, in non-randomness, population elements are selected on the basis of convenience, because they are easy or inexpensive to reach.
True or false

Expert Solution

Answer: Here, we need to understand the difference between two terminologies as mentioned below:


a) Probability Sampling:

It refers to the methodology of selecting the samples from the entire population, considering, two very important factors. First, the selection of each unit is based on the 'chance' or 'probability' or 'randomness'; and Second, each unit of the population has an independent and non-negative probability (chance) associated with that particular unit for being selected in a sample.

As this method of selecting a sample from the population is very time consuming and costly, there is another method called "Non-Probability Sampling"

Example: Withdrawing a lottery ticket from a box of 1000 tickets is an example of probability sampling

b) Non-Probability Sampling:

This is the method of selecting samples from the population, wherein no randomness is involved. Further, here, practically it's not possible to calculate the odds of each unit of the population to be selected as its very time consuming and costly. Rather, the sample units are selected from the population considering various factors such as the researcher's convenience, respondent's ease, researcher's judgment, etc.

Example: News reporter selects random person based on his / her judgment, and asks the question for their views on upcoming elections.

Conclusion: Based on the above discussion, we conclude that the given statement is "True".
