For example: “The results are statistically significant with 95% confidence” indicates that the alpha was 0.05, meaning there's a 1 in 20 chance of error in the results.
a simple chart for clarity is the best way to start.
Since I’m testing two variations (Subject Line A and Subject Line B) and two outcomes (opened, did not open), I can use a 2x2 chart:
Outcome
Subject Line A
Subject Line B
Total
Opened
X (e.g., 125)
Y (e.g., 135)
X + Y
Did Not Open
With (eg, 375)
W (eg, 365)
From + In
Total
X + Z
Y + W
N
This makes it easy to visualize the data and georgia phone number material calculate your Chi-Squared results. Totals for each column and row provide a clear overview of the outcomes in aggregate, setting you up for the next step: running the actual test.
While tools like HubSpot's A/B Testing Kit can calculate statistical significance automatically, understanding the underlying process helps you make better testing decisions. Let's look at how these calculations actually work:
