Calculate the test statistic (Z-score) Determine the Z score by subtracting the conversion rate of Alternative A from that of Alternative B, then dividing the result by the square root of the sum of the squared standard errors. Step 5: Calculate the p-value Use the =NORMSDIST() function in Excel to find the p-value associated with the Z score calculated in step 4. If the p-value is less than 0.05, the difference between the two variants is considered statistically significant.
FAQ What is the P-value and why is it important Job Function Email List for statistical significance? A p-value is like a test score that tells us if there's something special going on or if it's just a coincidence. If the p-value is low (usually less than 0.05), it means that the observed feature is probably not a simple coincidence, allowing us to have more confidence in the results. FAQ : What is Z-score and why is it important for statistical significance.
A core is a sort of measuring stick that tells us how far something is from what is normal or expected. It helps us determine whether the difference we observe between two things is truly special or just chance. decisions based on what we learn.
