Definitions:

Groups

Collections of subjects, items, or observations often categorized based on specific characteristics for analysis.

Two-Tailed T Test

A statistical hypothesis test used to determine if there is a significant difference between the means of two groups, with no presumption about the direction of the difference.

Null Hypothesis

A statement or hypothesis that suggests there is no statistical significance between the two variables being studied or no effect of an experimental variable.

P > 0.05

Indicates that the probability of obtaining the observed data, or more extreme, under the null hypothesis is greater than 5%, suggesting results are not statistically significant.
