Understanding the T-Test Basics by abhilashaupadhyaya is a document available to read on EtoBox.
A t-test is a statistical method used to compare the means of two groups, applicable in hypothesis testing to determine differences or effects. It requires assumptions of independence, normal distribution, and homogeneity of variance, with options for one-sample, two-sample, or paired tests based on the data structure. The t distribution is utilized when population variance is unknown and sample sizes are small, with degrees of freedom calculated as (N-1).
