Frequently Asked Questions
When should I use mean vs median?
Use mean for normally distributed data, median for skewed data or when outliers are present. Median is less affected by extreme values.
What does standard deviation tell me?
Standard deviation measures data spread around the mean. Low values indicate data points cluster near the mean; high values show more variation.
How do I interpret confidence intervals?
A 95% confidence interval means if you repeated the study 100 times, 95 intervals would contain the true population parameter.
