Statistics Sampling Techniques Pptx This document provides an overview of sampling techniques. 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. Sampling techniques.pptx free download as powerpoint presentation (.ppt .pptx), pdf file (.pdf), text file (.txt) or view presentation slides online. this document discusses different sampling techniques used in qualitative and quantitative research.
Sampling Techniques In Statistics Pptx Random sampling simple random sample – a sample designed in such a way as to ensure that (1) every member of the population has an equal chance of being chosen and (2) every combination of n members has an equal chance of being chosen. Supported by a systematic literature review (slr) with an in depth analysis of 34 articles from scopus indexed and web of science databases journals, this paper identifies, analyzes and describes the difficulties and opportunities in the social innovation and social entrepreneurship literature. Though human behaviour, which is the basis for any social research, is complex, there is underlying homogeneity and common problems that may help to draw representative sample. *stratified sampling*: stratified sampling involves dividing the population into distinct subgroups or strata and then sampling from each stratum. this technique is useful when the population is heterogeneous and the researcher wants to ensure that each subgroup is adequately represented.
Sampling Techniques Statistics And Probability Pptx Though human behaviour, which is the basis for any social research, is complex, there is underlying homogeneity and common problems that may help to draw representative sample. *stratified sampling*: stratified sampling involves dividing the population into distinct subgroups or strata and then sampling from each stratum. this technique is useful when the population is heterogeneous and the researcher wants to ensure that each subgroup is adequately represented. One of the most common types of nonprobability sample is called a convenience sample – not because such samples are necessarily easy to recruit, but because the researcher uses whatever individuals are available rather than selecting from the entire population.

Systematic random sample • divide the population size by the sample size, to get sampling fraction • select a random number between 1 and sampling fraction, which is the first sampling unit • systematically select the remaining sample units, by adding sampling fraction. It describes probability sampling techniques like simple random sampling, systematic random sampling, stratified random sampling and cluster sampling. it also discusses non probability sampling techniques and provides examples.
