Simple random sampling is one of the types of probability sampling that exist. Have you used it? Do you know how it differs from the others?
We know that one of the most important topics for market research is sampling, so we have prepared a series of information that we hope will be helpful to you about this method, its advantages and disadvantages, and how to use it in the best way.
What is simple random sampling?
Simple random sampling is a type of sampling that involves selecting a random subset of individuals from the target population to represent the entire group.
Simple random sampling is a probability sampling procedure that gives each element of the target population and each possible sample of a given size the same probability of being selected.
This is a technique used in market research to collect data from a jordan phone number sample of a larger population.
However, this sampling method is not the only one used in consumer research, especially because it is difficult to obtain a sampling frame from which to draw randomly .
It is important to note that simple random sampling does not guarantee a perfect representation of the population, but it increases the probability of obtaining a representative sample .
To improve the accuracy of the results, it is also important to ensure that the sample size is large enough to provide a statistically significant result.
Usually, to do research of this type, store users or consumers of certain products or certain specific areas are required to be the sampling units.
Let us not forget that a very important part of sampling consists of having the correct sample size, so as not to have a sampling error, which should be as minimal as possible.

How to perform simple random sampling?
Below we will show you how to perform a simple random sampling through 6 fundamental steps:
Define the target population.
Identify a current sampling frame of the target population or develop a new one.
Evaluate the sampling frame for undercoverage, overcoverage, multiple coverage, and clustering, and make adjustments as necessary.
Assigns a unique number to each element of the plot.
Determine the sample size .
Randomly select the specified number of elements from the population.
