WebApr 25, 2024 · T-test. The t-test is a parametric test that compares the means of the samples and populations involved. There are several varieties of t-tests. A one-sample t-test compares the mean of a sample with a hypothesized mean. An independent samples t-test looks at whether the means of two different samples have similar values. WebOct 26, 2024 · The Physics Subject Test contained 75 multiple-choice questions about major physics concepts, such as thermodynamics, magnetism and electricity, kinematics, and gravity.
