Interpreting the t statistic
WebHere is how Microsoft explains how to interpret the output here: “Under the assumption of equal underlying population means, if t < 0, “P (T <= t) one-tail” gives the probability that a value of the t-Statistic would be observed that is more negative than t. If t >=0, “P (T <= t) one-tail” gives the probability that a value of the t ... WebJun 4, 2024 · A negative t-value indicates a reversal in the directionality of the effect, which has no bearing on the significance of the difference between groups. Analysis of a negative t-value requires examination of its absolute value in comparison to the value on a table of t-values and degrees of freedom, which quantifies the variability of the final ...
