There are 2 types of stratified sampling methods: proportional and non-proportional. Indeed, all other methods of scientific sampling are variations of the simple random sampling. Multi-Phase Sampling. Random Sampling Techniques. In this article, let us discuss the different sampling methods in research such as probability sampling and non-probability sampling methods and various methods involved in those two approaches in detail. The selection of random type is done by probability random sampling while the non-selection type is by non-probability probability random sampling. In the proportional sampling, equal and proportionate representation is given to subgroups or strata. If the number of items is large, then the sample will have a higher size and vice versa. Simple Random Sampling: Simple random sampling is in a sense, the basic theme of all scientific sampling. Type # 1. Outcome of sampling might be biased and makes difficult for all the elements of population to be part of the sample equally. Stratified Sampling: Population divided into different groups from which we sample randomly ! There are numerous ways of getting a sample, but here are the most commonly used sampling methods: 1. Random Sampling. Furthermore, as there are different types of sampling techniques/methods, researcher needs to understand the differences to select the proper sampling method for the research. The target group/population is the desired population subgroup to be studied, and therefore want research findings to generalise to. Simple Random Sampling: Every member of the population is equally likely to be selected) ! Random sampling methods ! It is the primary probability sampling design. Simple random sampling requires using randomly generated numbers to choose a sample. More specifically, it initially requires a sampling frame, a list or database of all members of a population. A target group is usually too large to study in its entirety, so sampling methods are used to choose a representative sample from the target group. The purest form of sampling under the probability approach, random sampling provides equal chances of being picked for each member of the target population. Non-Probability Sampling. Basic Sampling Techniques. There are 4 types of random sampling techniques: 1. Types of Sampling Method. In Statistics, there are different sampling techniques available to get relevant results from the population. Stratified Sampling This technique is more reliant on the researcher’s ability to select elements for a sample. Systematic Sampling: Simple Random Sampling in an ordered systematic way, e.g. It does not rely on randomization. Simple Random Sampling. Optimum Allocation Sample 7. This type of sampling is also known as non-random sampling. every 100th name in the yellow pages ! Cluster sampling 8. 2. A population is an entire group with specified characteristics.
