WebJan 22, 2024 · To test if the slope coefficient is statistically significant, we can calculate the t-test statistic as: t = b 1 / se(b 1) t = 2.7037 / 0.7456; t = 3.626; The p-value that corresponds to this t-test statistic is shown in the column called Pr(> t ) in the output. The p-value turns out to be 0.00464. Since this p-value is less than 0.05, we ... WebFeb 8, 2024 · To calculate the t-value for an equal variance test, you can use the following formula: t=mean1-mean2n1-1)×var12+ (n2-1)×var22n1+n2-21n1+1n2. Wherein, mean1 and mean2 represent the average values of the sample sets; var1 and var2 are the variances of the sample sets; and. n1 and n2 represent the sizes of the data set.
