P-values show up in many places, including, as further examples, in linear regression, where p-values assess the significance of model coefficients, or in ANOVA testing. Take our Introducton to Statistics course
When it comes to analyzing data, P-value is an essential concept that helps to determine the significance of the results obtained from regression or correlation analysis. However, calculating P-value manually can be a daunting task, with a high probability of errors. That's where spreads...
Apparently, the Data Analysis Regression tool arbitrarily replaces those errors with 65535 for t-stat and #NUM for p-value. We know that 65535 is arbitrary because if it were the actual t-stat, the p-value would be TDIST(65535, 30-2, 2), which returns 3.7449E-116, not an Excel erro...
F-statistic: 1.16e+03 on 1 and 270 DF, p-value: <2e-16 Decide whether there is a significant relationship between the variables in the linear regression model of the data setfaithfulat .05 significance level. NULL hypothesis: no relationship between x and y, so the slope is zero. 假设...
With Excel's Data Analysis Regression option, I'm getting #NUM! for P-values and my t-Stat is the same number as the adjusted R squared. I'm just...

If you are assuming equal variances, then this assumption should be tested (similar to testing the residuals in a Regression or ANOVA test for normality to meet their respective assumption).CautionP-value calculations in spreadsheets such as Excel can be tricky. Even when using statistical software...
http://faculty.vassar.edu/lowry/rsig.html A correspondent asked how to use StatTools to show the p-value for a correlation, without doing a full regression. This can't be done directly in StatTools, but the calculations are not too difficult in Excel. ...
