Document Summary

Simple random sample: researcher develops an accurate sampling frame, selects elements from the sampling frame according to a mathematically random procedure then locates the exact element that was selected for inclusion in the sample. After numbering all elements in a sampling frame, researcher uses list of random numbers to decide which elements to select. There needs to be as many random numbers as there are elements to be sampled: ex. Sample of 100, 100 random numbers needed: random numbers can came from random-number table (table of numbers chosen in mathematically random way) Unrestricted random sampling= random sampling with replacement (replacing an element after sampling so it can be selected again) With simple random sampling researcher ignores elements already selected into the sample. Set of many random samples = sampling distribution: distribution of different samples that shows the frequency of different sample outcomes from many separate random samples.
