Question

Which of the following is not a component of effective experimental designs in the early stages of a scientific study?

1) Random assignment of participants to groups
2) Control group
3) Manipulation of independent variable
4) Use of a large sample size

Answer 1

The component that is not a component of effective experimental designs in the early stages of a scientific study is the use of a large sample size.

Step-by-step explanation:

The component that is not a component of effective experimental designs in the early stages of a scientific study is the Use of a large sample size. While having a large sample size can increase the statistical power and reliability of the results, it is not a core component of experimental design. The other three options, random assignment of participants to groups, control group, and manipulation of independent variable, are all essential components of effective experimental designs in the early stages of a scientific study.

Random assignment of participants to groups: This minimizes selection bias and ensures that each participant has an equal chance of being in any experimental group.

Control group: A group that does not receive the experimental treatment, serving as a baseline for comparison.

Manipulation of independent variable: The intentional change applied to assess its effect on the dependent variable.
