Descriptive Statistics
- • Mean: Average of all values
- • Median: Middle value when sorted
- • Mode: Most frequently occurring value
- • Standard Deviation: Measure of data spread
- • Quartiles: Values that divide data into quarters
Correlation & Regression
- • Correlation: Strength of linear relationship (-1 to 1)
- • Regression: Best fit line through data points
- • R²: Proportion of variance explained by the model
- • Z-Score: How many standard deviations from the mean
Interpretation Tips
- • Correlation does not imply causation
- • Outliers can significantly affect statistics
- • Larger sample sizes provide more reliable results
- • Consider the context when interpreting results
