Identify the sampling techniques used, and discuss potential sources of bias (if any). Explain.
After a tornado, a disaster area is divided into 150 equal grids. Fifty of the grids are selected, and every occupied household in the grid is interviewed to help focus relief efforts on what residents require the most.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
What type of sampling is used?
a) Stratified sampling is used, since the disaster area is divided into grids, and some of those grids are selected and everyone in those grids is interviewed.
b) Cluster sampling is used, since the disaster area is divded into grids, and a random sample is taken from each grid.
c) Cluster sampling is used, since the disaster area is divided into grids, and some of those grids are selected and everyone in those grids is interviewed.
d) Stratified sampling is used, since the disaster area is divded into grids, and a random sample is taken from each grid
Homework Answers
In stratified sampling technique, the sample is created out of the random selection of elements from all the strata while in the cluster sampling, all the units of the randomly selected clusters form a sample.
Hence answer here is
c) Cluster sampling is used, since the disaster area is divided into grids, and some of those grids are selected and everyone in those grids is interviewed.
