Definition: The Sampling Error refers to the statistical error occurred when the subset of the population (sample) deviates from the true characteristics, attributes and behavior of the total population. Simply, when the sample selected from the population differs from the actual attributes of the target population, then the sampling error arises. Basically, there are two … [Read more...] about Sampling Error

Definition: The Multistage Sampling is the probability sampling technique wherein the sampling is carried out in several stages such that the sample size gets reduced at each stage. The multistage sampling is a complex form of cluster sampling. The cluster sampling is yet another random sampling technique wherein the population is divided into subgroups called as clusters; … [Read more...] about Multistage Sampling

Definition: The Systematic Sampling is yet another probability sampling technique wherein the starting point from where the element is to be drawn from the population is chosen randomly and then the subsequent items are selected on the basis of the fixed periodic interval between the sample items. The systematic sampling is a periodical method wherein the sample members are … [Read more...] about Systematic Sampling

Definition: The Stratified Sampling is a sampling technique wherein the population is sub-divided into homogeneous groups, called as ‘strata’, from which the samples are selected on a random basis. The strata are formed on the basis of the member’s shared attributes and characteristics. These are mutually exclusive as every item of the population is assigned to a single … [Read more...] about Stratified Sampling

Definition: The Simple Random Sampling is a sampling technique wherein every item of the population has an equal and likely chance of being selected in the sample. Here, the selection of the item solely depends on the chance and therefore, this method is also called as a Method of Chance Selection. The selection of samples through simple random sampling is free from the … [Read more...] about Simple Random Sampling

Definition: The Sampling is a statistical process of selecting few representatives from the population, called as a sample, on the basis of which the characteristics of the total population can be ascertained.
