Key Concepts

Experimental Design

This is a research framework that involves planning, structuring, and analyzing a study to investigate causal relationships. In experimental designs, treatments are applied to different groups under controlled conditions to isolate the effect of an independent variable.

Treatment Effects

Treatment effects refer to the differences in outcomes between groups that receive different experimental manipulations. Assessing treatment effects involves comparing the means or distributions of the measured outcomes to determine if the treatment has a significant impact.

Analysis of Variance (ANOVA)

ANOVA is a statistical method used to analyze differences among group means in an experiment, particularly when there are more than two groups or treatment conditions. It evaluates the variance between groups relative to the variance within groups to determine if observed differences are statistically significant.

t-test

A t-test is a statistical test used to compare the means of two groups to see if they differ significantly. It is especially useful in experimental designs that involve only two groups, such as a treatment group and a control group.
