WebFor a single mean, you can compute the difference between the observed mean and hypothesized mean in standard deviation units: \[d=\frac{\overline x - \mu_0}{s}\] For correlation and regression we can compute $r^2$ which is known as the coefficient of determination. This is the proportion of shared variation. WebPaired t-tests are typically used to test the means of a population before and after some treatment, i.e. two samples of math scores from students before and after a lesson. The result of this tool is a calculated t-value. This value can be negative or positive, depending on the data. Assuming that the population means are equal: If t < 0, P (T ...
