Explanation

The factors influencing sample size are the type of project, the purpose of the project, and previous research in the area.

The type of project shapes how large and precise the sample must be.

The purpose of the project sets the level of accuracy and detail that is needed.

Previous research in the area guides expected effect sizes and variability.

The researcher's personality has no bearing on the required sample size.

The researcher's standing likewise does not determine how many cases to sample.
