It defines key sampling terms like population, sample, sampling frame, and discusses the need for sampling due to constraints of time and money for a full census. Some examples of probability sampling techniques include simple random sampling, systematic sampling Statistical Sampling. It discusses different sampling methods, important sampling terms, and statistical tests. The goals of sampling are discussed as reducing costs, increasing efficiency and Sampling Research Methods for Business This document provides an overview of sampling techniques. , persons, households) in the population have some opportunity of being included in the sample, and the mathematical probability that any one of them will be selected can be calculated. The key points are: 1) There are two ways to collect statistical data - a complete enumeration (census) or a sample survey. Probability sampling techniques like simple random sampling, stratified sampling, and systematic sampling are explained.

Each technique has advantages and disadvantages related to accuracy, cost, and generalizability 47 Disproportionate Stratified Sample Stratified Random Sampling Stratified random sample – A method of sampling obtained by (1) dividing the population into subgroups based on one or more variables central to our analysis and (2) then drawing a simple random sample from each of the subgroups Reduces cost of research (e. It defines key terms like population, sample, sampling, and element. Are you new to PowerPoint? This is a step-by-step topic to help you create a basic presentation using PowerPoint This document provides an overview of sampling techniques for teaching basic statistics. It describes two main sampling techniques - probability sampling which uses random selection, and non-probability sampling which uses non-random methods. Probability sampling methods like simple random sampling, stratified random sampling, and systematic random sampling aim to provide an unbiased representation of the population. It also describes different sampling methods like simple random sampling, stratified random sampling, systematic random sampling, and cluster sampling. ppt / . A guide for gathering data. A sample is a portion of a population that is examined to estimate population characteristics.
