Statistics Tips
Outlier Detection
Values more than 1.5 * IQR below Q1 or above Q3 are often considered outliers in your data.
Mean vs Median
If mean and median differ significantly, your data may be skewed. Median is often more robust for skewed data.
Sample Size Matters
Statistics from small samples (< 30) may not be representative. Larger samples provide more reliable estimates.
