📖How to Use
- 1Enter data values (comma or newline separated)
- 2Mean, median, mode, variance, and standard deviation are calculated automatically
- 3Visualize the distribution with histograms and box plots
💡Tips & Knowledge
- •When outliers are present, the median better reflects the typical value than the mean
- •A smaller standard deviation means data is more tightly clustered around the mean
- •For normal distributions, ±1σ covers ~68% and ±2σ covers ~95% of data (68-95-99.7 rule)
