The most appropriate methodology for drawing a sample from 3,000 time cards to check for signatures would be
a. interval sampling.
b. cluster sampling.
c. stratified sampling.
d. variables sampling.

Cluster sampling

Explanation:

cluster sampling is also called a simple random sampling.

In this sampling, the researchers, select the variable either by simple random sampling or systematic random sampling. the researcher just not to includes the sub-part of sampling but even can include the main sampling in it. in this sampling, the researcher used a geographical cluster to do the sampling in a population.

For example, if a researcher wants to sample n an academic population:

answer; deviation iq; //(a)

they could find out our specific needs.
