Question

What are the 3 problems avoided by Alternating Treatments Design?

1) Order effects, carryover effects, and practice effects
2) Sampling bias, selection bias, and measurement bias
3) Confounding variables, extraneous variables, and dependent variables
4) Random assignment, control group, and experimental group

Answer 1

The three problems avoided by Alternating Treatments Design are order effects, carryover effects, and practice effects. This design helps eliminate these problems by randomly assigning the order of treatments and allowing all subjects to experience both treatments.

Step-by-step explanation:

The three problems avoided by Alternating Treatments Design are order effects, carryover effects, and practice effects. Order effects occur when the order in which treatments are administered affects the outcome of the study. Carryover effects happen when the effects of one treatment carry over to the next treatment, influencing the results. Practice effects occur when participants become more skilled or experienced as they go through the treatments. Alternating Treatments Design is a research design that helps eliminate these problems by randomly assigning the order of treatments and allowing all subjects to experience both treatments.
