Sometimes you do a t test and get a negative t value What do you do with that and how do you report it Let s answer how you should interpret a negative t value or a negative Yes it is indeed possible to obtain a negative t value It eventually depends on the formulation of the test statistics As pointed out by Etuk the formula of the test statistics can be value
T tests use t values to compare sample means to null hypotheses T values are unitless statistics that vary depending on the sample size and variation T distributions show the probability of observing t values if the null hypothesis is In this post I will explain t values t distributions and how t tests use them to calculate probabilities and assess hypotheses What Are t Values T tests are called t tests because the test results are all based on t values T

Can t test statistics be a negative number If the sample mean is less than the population mean then the difference will be negative t statistic for mean x s n So if In simple terms a negative confidence interval in this setting means that although observation is that mean of group 2 is 0 028 higher than group 1 the 95 confidence interval
First T values can be anything A t statistic generally is just statistic parameter Standard error So if your parameter is set to zero i e the null hypothesis is that parameter 0 then No we do not need to ignore the negative sign in calculated t test value A negative t value simply means that the difference between the means of the two groups is
