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 estimated number. If the absolute value of the experimental t-value is smaller than the value found on the degrees of freedom chart, then the means of the two groups can be said to be significantly different.

The t stat is - value is normal to have a negative value

Ousaad please I want to know if it is normal to have a negative or minus value in my findings

Can you please tell me if my analysis are correct I followed what u have done here in this vd
But I get two negative values in the Pearson correlation -0.111
And in the t. Stat -3.429244
But in the p value it is less than 0.05 and we can say that the alternative hypothesis can be adopted
