Key Analytics Concepts
Statistical Significance
Statistical significance indicates whether observed differences in your data are likely to be real or just due to random chance. A result is typically considered statistically significant when there's less than a 5% probability (p < 0.05) that the observed difference occurred by chance.
Confidence Intervals
A confidence interval provides a range of values that likely contains the true value of a metric. A 95% confidence interval means that if you repeated the experiment 100 times, approximately 95 of those intervals would contain the true value.
Conversion Rate
The percentage of visitors who complete a desired action (purchase, signup, download). Formula: (Conversions / Total Visitors) × 100
Customer Lifetime Value (LTV)
The total revenue you can expect from a customer throughout their relationship with your business. Formula: Average Purchase Value × Purchase Frequency × Customer Lifespan
Churn Rate
The percentage of customers who stop using your product or service during a given time period. Formula: (Customers Lost / Total Customers at Start) × 100
Compound Annual Growth Rate (CAGR)
The mean annual growth rate over a specified period longer than one year. Formula: ((Ending Value / Beginning Value)^(1/Years) - 1) × 100
