How do i find a p value
WebJun 11, 2024 · P-Values, or probability values, help us understand the statistical significance of a finding. The P-Value is used to test the likely validity of the null hypothesis. If the null hypothesis is considered improbable according to the P-Value, then that leads us to believe that the alternative hypothesis might be true. WebMay 7, 2024 · To find the p-value, we can first locate the value -0.84 in the z table: Since we’re conducting a two-tailed test, we can then multiply this value by 2. So our final p-value is: 0.2005 * 2 = 0.401. Additional Resources. The following tutorials explain how to calculate p-values from z-scores using various statistical software:
