Part 1

What type of sampling is​ used?

A.

Cluster sampling is​ used, since the field is divided into​ subplots, a number of subplots are​ selected, and every

wheatwheat

plant in the selected subplots is sampled.

B.

Convenience sampling is​ used, since the

wheatwheat

plants closest to the barn are sampled.

C.

Simple random sampling is​ used, since each sample of

wheatwheat

plants of the same amount has the same chance of being selected.

D.

Stratified sampling is​ used, since the field is divided into subplots and a random sample is taken from each subplot.
