May result in answering the question without even understanding it or even leaving a few questions out. In this case, the researcher is able to minimize or eliminate sampling error.Another possible cause of this error is chance. http://www.slideshare.net/rambhu21/sampling-and-sampling-errors-19870549
Types Of Sampling Errors In Research
Sampling Error: It occurs when a probability sampling method is used to select a sample and this sample is not representative of the population concerned. It is very easy and convenient to draw the sample fromhomogenous population 6.

In the absence of a direct assessment of error, methodologists measure error in a roundabout way. Difference Between Sampling Error And Nonsampling Error Therefore, generalizability is neverstatistically appropriate.Non Probability Sampling 44. Multistage sampling refers to sampling planswhere the sampling is carried out in stagesusing smaller and smaller sampling units at eachstage.Not all Secondary Units Sampled normally usedto overcome problems associated with ageographically

Why Does This Error Occur? Random Sampling Error Example Ways to Eliminate Sampling Error There is only one way to eliminate this error.
Total error has two distinct components: Total Error= Sampling Error+ Non Sampling Error 2. Sampling process error occurs because researchers draw different subjects from the same population but still, the subjects have individual differences.

The population is divided into subgroups(clusters) like families. For example, a random sample of 500 people composed only of people between 35-50 years of age may not be representative of adult population. Then, imagine increasing the sample size to 100, the tendency of their scores is to cluster, thus a low standard deviation. . Non Sampling Error consists of all other error associated with the research project.

More technically, it is the average difference of all the actual scores of the subjects from the mean or average of all the scores. Refusal arises when the respondent does not respond to a particular item or to multiple items of the questionnaire.
