Mathematically, the p-value is calculated using integral calculus from the area under the probability distribution curve for all values of statistics that are at least as far from the reference value as the observed value is, relative to the total area under the probability distribution curve. Sta...

Method 2 – Using the T.TEST Function In this section, we will be using theT.TEST functionto determine thePvalues for tails1and2. Calculate P-Value for Tail 1 (One Direction): In cellF5, enter the following formula: =T.TEST(C4:C11,D4:D11,1,1) ...
calculating P-value manually can be a daunting task, with a high probability of errors. That's where spreadsheet tools come in handy, allowing you to calculate P-value with a few clicks. If you're
Variable 2 Range:B1 to B7 Labels:Tick the checkbox Output Range: E1. After entering the above data, click on“OK”. Excel will provide a detailed result for the p-value in cellsE1toG14,as shown below: Result: The tool gives us two p-values: one for a one-tailed t-test and the ...
correct for multiple comparisons; Fishers LSD test does not. The "exact" P values computed by the two methods, therefore, will give very different results and must be interpreted very differently. If you report either, be sure to be very explicit about exactly what P...
At present,I can do many things in a superficial level, but not be competent to do things professionally owing to lack of ample knowledge and ability. In my opinion, further study is actually urgent for me to realize and finally achieve self-value. ...
So you need to find the p-value for your hypothesis test. To do so, employ the spreadsheet program Microsoft Excel. Using a simple formula, you can easily determine the p-value for your tests and thereby conclude strong or weak support of the null hypoth

your research, the alpha level would be 2% (100% – 98%). When you run the hypothesis test, the test will give you a value for p. Compare that value to your chosen alpha level. For example, let’s say you chose an alpha level of 5% (0.05). If the results from the test give ...
