Introduction
Note: The assessments in this course build upon each other, so you are strongly encouraged to complete them in sequence.
Procedures examined in this assessment are fundamental for quantitative methodology. Random sampling, in which each participant has an equal chance of being selected, is needed to avoid biases that can distort results. It is necessary to undersr=tand a variety of sampling methods and how sample size and other factors affect the shape of the distribution.
In this assessment, you will examine sampling methods and take a look at the effect of d=sample size and power. You will also practice methods of defining variables, testing hypotheses, and t tests.
