Apprendre Visualizing A/B Test Results | Optimizing Growth Experiments

When you run A/B tests, the ability to visualize results is crucial for communicating outcomes to stakeholders who may not be familiar with statistical details. Visualizations transform raw numbers into clear, digestible insights, making it easier for decision-makers to understand which variant performed better and by how much. Effective charts can highlight key differences, trends, and the overall impact of your experiments, ensuring that your findings drive actionable decisions.

import matplotlib.pyplot as plt

# Example conversion rates for groups A and B
groups = ['A', 'B']
conversion_rates = [0.12, 0.17]

plt.bar(groups, conversion_rates, color=['#3498db', '#e74c3c'])
plt.ylabel('Conversion Rate')
plt.title('A/B Test Conversion Rate Comparison')
plt.ylim(0, 0.25)
plt.show()

Customizing your chart elements helps ensure your message is clear. In the code above, different colors distinguish group A from group B, and labels such as "Conversion Rate" and a descriptive title make the chart self-explanatory. Setting a suitable y-axis limit (here, from 0 to 0.25) prevents the chart from exaggerating differences and keeps focus on the actual data range, making interpretation straightforward for all viewers.

plt.ylabel('Conversion Rate')
plt.title('A/B Test Conversion Rate Comparison')
plt.ylim(0, 0.25)

# Annotate bars with conversion rate values
for bar, rate in zip(bars, conversion_rates):
    plt.text(
        bar.get_x() + bar.get_width() / 2, 
        bar.get_height() + 0.01, 
        f"{rate:.2%}", 
        ha='center', va='bottom', fontsize=10
    )

plt.show()
