How can one interpret a negative t-value in a student test (p-value is very low)?
I have a question about interpreting t-values in a student test. What does a negative t-value indicate if the p-value is very low?
A negative t-value indicates that the sample mean is lower than the population mean. If the p-value is very low, then it means that the observed difference is statistically significant and unlikely due to chance.
