Does Excel t-test give you p value?
When you run the t-test, EXCEL will provide a printout that contains the mean values and other information. The most important part of these results is the p-value. The p-value tells you in an unbiased manner whether you must accept or reject the null hypothesis. Open a blank spreadsheet in EXCEL.
What does negative t-statistic mean?
A negative t-statistic simply means that it lies to the left of the mean . The t-distribution, just like the standard normal, has a mean of 0 . All values to the left of the mean are negative and positive to the right of the mean.
What is the p-value for t-test?
Every t-value has a p-value to go with it. A p-value is the probability that the results from your sample data occurred by chance. P-values are from 0% to 100%. They are usually written as a decimal.
How do you know if a test is statistically significant?
If the computed t-score equals or exceeds the value of t indicated in the table, then the researcher can conclude that there is a statistically significant probability that the relationship between the two variables exists and is not due to chance, and reject the null hypothesis.
What type of t-test should I use?
If you are studying one group, use a paired t-test to compare the group mean over time or after an intervention, or use a one-sample t-test to compare the group mean to a standard value. If you are studying two groups, use a two-sample t-test. If you want to know only whether a difference exists, use a two-tailed test.

Do you report negative T values?
Dear t value can be reported as negative on the basis of P- value. However the possibility of negative t- value is rare.
