Obtaining a SRS is generally more costly than other forms of sampling.
If a sample of 1,000,000 families is randomly selected from all of Canada (with about 8,000,000
families) and the average family income is computed, then the true value of the family income
for all families in Canada is known.
O In a proper random sampling, every element of the population has a known (and often equal)
chance of being selected.
O Convenience sampling often leads to biases in estimates since the sample is often not
representative of the population.
