a researcher wants to survey people from different age groups to analyze voting patterns. which type of survey will best accomplish this goal?\nsystematic random sampling\nvoluntary sampling\nconvenience sampling\nstratified sampling
Answer
Brief Explanations:
Stratified sampling divides the population into subgroups (strata) based on certain characteristics (here, age groups). Then samples are taken from each stratum. This ensures representation from all age - groups for analyzing voting patterns. Systematic random sampling selects elements at regular intervals, voluntary sampling is self - selected by participants, and convenience sampling is based on ease of access, none of which are as effective as stratified sampling for this goal.
Answer:
stratified sampling
