Evaluating Business Experiments
Business experiments, such as A/B tests, are essential tools for startup founders who want to make informed, data-driven decisions. By designing controlled experiments, you can compare different strategies or product features to see which approach leads to better outcomes, like higher conversion rates or increased user engagement. Evaluating the results of these experiments is crucial for understanding what works and for justifying changes to your product or business strategy. Without proper evaluation, you risk making decisions based on guesswork rather than evidence.

To evaluate a business experiment, you often start by calculating the conversion rate for each group. The conversion rate is the percentage of visitors who take a desired action, such as signing up or making a purchase. In the code above, you divide the number of conversions by the number of visitors for each group. Comparing these rates tells you which version performed better, but it does not tell you if the difference is statistically significant. Interpreting these results means looking beyond raw percentages and considering whether the observed difference is likely due to the changes you made, or just random chance.
