Question

Experiments use random assignment to avoid which of the following?

Select one:
a. Selection effects
b. Random selection
c. Carryover effects
d. Demand characteristics

Answer 1

Random assignment is used in experiments to avoid selection effects and control for lurking variables, allowing differences between groups to be attributed to the experimental treatment.

Step-by-step explanation:

Experiments use random assignment to avoid selection effects. Random assignment is a critical part of the experimental design, ensuring that there are no systematic differences between the groups prior to the start of the experiment. By randomizing group allocation, the differences observed between experimental and control groups can be attributed to the manipulation of the independent variable, rather than preexisting differences. Consequently, this eliminates the problem of lurking variables, which might otherwise influence the outcomes in an uncontrolled manner.
