  2. Finally, as shown in the example below, the p-value of the test result and whether or not the null hypothesis (Ho) is rejected are displayed.

 

 p = 0.07xxxx NS (2 tails)
    ➡ Ho is not rejected. (When set to α=0.05 or α=0.01)
 p = 0.04xxxx* (2 tails)
    ➡ Ho is rejected. (When set to α=0.05 or α=0.01
 p = 0.003xxx** (2 tails)
    ➡ Ho is rejected. (When set to α=0.01)

 

  This app uses α=0.05 or α=0.01 as the significance level, but if you have decided on a different significance level, please compare your significance level with above p-value.
