Definitions:

Level of Significance

The level of significance is a threshold set by the researcher to determine the cutoff at which the null hypothesis can be rejected, commonly represented by alpha (α).

T-statistic

A statistical measure used to analyze the difference between two group means in relation to the variance observed within the groups.

Alpha

Alpha, often represented as α, is the threshold probability of committing a Type I Error, typically set at 0.05 or 5% in hypothesis testing.

T-statistic

The T-statistic is a ratio used in hypothesis testing that compares the difference between an observed sample mean and a known value, to the standard error of the mean.
