Sampling Vs. Stratified Random Sampling
Sampling involves selecting a subset of elements from the population. In this case, Stratified Random Sampling, and Simple Random Sampling plans are compared as data collection methods for a sample that a researcher would consider using for a business survey for a marketing/advertising campaign. Simple Random Sampling is a sampling procedure whereby the researcher defines the target population and then selects a sampling frame from the population. He then selects individual elements within the sampling frame with each element having an equal probability of being chosen. Stratified Random Sampling is similar to Simple Random Sampling in that it is also a probability sampling technique. However, there exists a major difference in that, with Stratified random sampling, the researcher divides the population into different groups called strata. He then selects individual elements from each stratum at random. The same probability of being selected applies for each of the elements in the population. As such, stratified sampling requires that the strata should not overlap in order to avoid some elements in the population having a higher chance of being selected than others. The most common used strata include; age, socioeconomic status, religion and nationality.

Methods Of Using Stratified Sampling Essay
2343 Words  10 PagesOhio, Tennessee, West Virginia, and Virginia. The participating facilities and the inmates were selected utilizing stratified sampling. From the total number of facilities (126), fifty facilities were randomly selected. The facilities were selected by grouping them into different security levels (maximum, medium, and minimum) and were all given a number and selected using a random number generator. Lists of all the inmates were collected from the facilities and 10,000 male inmates were randomly…

In efforts to understand more of this particular research, the stratified random sampling technique will allow for sampling among a particular population, in this case female combat veterans who have endured combat operational stress. In order to create a stratified random sample, I would take the following steps: 1. Define the…

NOT FOR COMMERCIAL DISTRIBUTION 3 Simple Random Sampling 3.1 INTRODUCTION Everyone mentions simple random sampling, but few use this method for populationbased surveys. Rapid surveys are no exception, since they too use a more complex sampling scheme. So why should we be concerned with simple random sampling? The main reason is to learn the theory of sampling. Simple random sampling is the basic selection process of sampling and is easiest to understand. If everyone in a population…
