which of the following is true of probability sampling


What is Probability Sampling?


Probability sampling is a type of sampling method where each individual in the population has a known, non-zero chance of being selected for the sample. Probability sampling allows researchers to make inferences about a population from a sample by using statistical analysis.

There are several different types of probability sampling methods, including:

-Simple Random Sampling: Every individual in the population has an equal chance of being selected for the sample. This is the most basic and common type of probability sampling.
-Systematic Random Sampling: individuals are selected for the sample at fixed intervals from a list of all individuals in the population.
-Stratified Random Sampling: The population is divided into subgroups (strata), and then a simple random sample is drawn from each stratum. This method is used when researchers want to ensure that the composition of the final sample reflects the composition of different subgroups in the population.
-Cluster Sampling: The population is first divided into groups (clusters). Then, a simple random sample of clusters is selected, and all individuals in those selected clusters are included in the final sample.

Probability sampling is a method of selecting a sample from a population in which each member of the population has a known and equal probability of being selected.

Probability sampling is a method of selecting a sample from a population in which each member of the population has a known and equal probability of being selected. This type of sampling is often used in situations where it is difficult or impossible to obtain a complete list of the members of the population, such as when studying a rare condition or phenomenon.

How is Probability Sampling Used?

Probability sampling is used in many different ways. Some common examples include choosing Every Nth individual from a population list (e.g., selecting every 10th person on a phone list), Random Sampling (e.g., selecting individuals using a random number table), and Systematic Sampling (e.g., selecting individuals by starting with a random individual and then selecting every 10th person thereafter).

Probability sampling is used in research in order to ensure that the results of a study are representative of the population as a whole.

Probability sampling is used in research in order to ensure that the results of a study are representative of the population as a whole. This type of sampling ensures that every member of the population has an equal chance of being selected for inclusion in the sample, and this makes it much easier to generalize the findings of a study to the population as a whole. Probability sampling is therefore considered to be much more reliable than non-probability sampling methods, such as convenience sampling.

What are the Benefits of Probability Sampling?

Probability sampling has a number of advantages over other methods of sampling. First, it allows researchers to quantify the degree of uncertainty associated with their estimates. This is because probability sampling provides a way to calculate a margin of error. Second, probability sampling is generally more efficient than other methods, such as convenience or judgmental sampling. This is because, with probability sampling, every element in the population has a known, non-zero chance of being included in the sample. Finally, probability samples are often easier to analyze than other types of samples.

Probability sampling is considered to be the most accurate method of sampling, as it minimizes the risk of bias and error.

What are the Disadvantages of Probability Sampling?

There are a few disadvantages of probability sampling to consider. First, it can be more expensive and time-consuming to select a random sample than a non-random one. Second, if the sampling frame is not representative of the population, then the results of the study may not be accurate. Finally, if the sample size is too small, it may not be representative of the population.

Probability sampling can be time-consuming and expensive, as it requires a complete list of the population from which the sample will be drawn.


Probability sampling is a type of scientific sampling method where samples are drawn from a population using random selection. Probability sampling is the gold standard for scientific research because it minimizes bias and allows researchers to make valid inferences about a population from a sample.

However, probability sampling can be time-consuming and expensive, as it requires a complete list of the population from which the sample will be drawn. In addition, probability sampling can be complex, as the process of randomly selecting units from the population can be difficult to achieve in practice.
