Document Summary

Soc sci 2j03 - lecture 3 - sampling errors. Is the difference between the result obtained from a sample survey and the result that would have been obtained if the whole population had been included in the survey. Variation from sample to sample will always exists. The errors that occur in the collection, recording and tabulation of data. Within a non-sampling error, there is a sampling frame which is a list of members within the target population that is used to select a sample. Listed below are four types of non-sampling errors: selection error or biases. When the sampling frame is not representative of the population, ex. telephone directory or magazine: non-response error or biases. The error that occurs because many of the people included in the sample don"t respond to a survey. It has been observed that families with low and high incomes do not respond to surveys by mail.
