In quantitative designs how does sampling error effect sample generalizability? Also, what four factors reduce sampling error?
Sample generalizability is significantly influenced by the size and representativeness of the sample. If the selection is not done properly and sample is not randomly selected, it can limit sample generalizability. Sample may not represent the population from which it has been drawn. For example, convenience sampling decreases generalizability.
Four factors that can reduce sampling error are:
– Choosing sample of respondents in an unbiased manner
– Using simple random sampling
– By increasing the size of the sample as the sampling error can be reduced by increasing the sample size.
– By using stratification. Population can be divided into different groups containing similar units.
