Overview
Determining a minimum threshold population for your quantitative study is critical for achieving a quality study.. Understanding these procedures is paramount in completing both your IRB application and effectively writing the sampling procedures portion of chapter three. In this discussion board, you will have the opportunity to conduct either a G*Power Analysis (quantitative)
Directions: Select the prompt below based on your dissertation’s chosen methodology.
Quantitative:
- Using the G* power analysis tool, calculate the minimum sample size needed for your study.

Example: The initial target population for the study was 420. The final sample size for the study was 520, which exceeded the minimum sample size of 55, it was determined by a G*Power analysis, a priori to establish a rigorous sample size (power = .80; effect = .15; α = .05).
