T stat threshold
WebStatistical significance. In statistical hypothesis testing, [1] [2] a result has statistical significance when a result at least as "extreme" would be very infrequent if the null hypothesis were true. [3] More precisely, a study's defined significance level, denoted by , is the probability of the study rejecting the null hypothesis, given that ... WebIf you switched A and B in the subtraction, you would just get a negative result (similar to how 5 - 3 = 2, but 3 - 5 = -2). Then when you used a t-table or the tcdf() function, you would just have to find the area of the high end of the distribution instead of the area of …
