Statistics for Archaeologists

Numerical Exploration: 1. Batches of Numbers (Stemandleaf Plots, Histograms). 2. The Level, or Center, of a Batch (Mean and Median). 3. The Spread or Dispersion of a Batch (Range, Midspread, and Standard Deviation). 4. Comparing Batches (The BoxandDot Plot). 5. The Shape or Distribution of a Batch (Symmetry and Transformations). 6. Categories (Column and Row Proportions) Random Sampling: 7. Samples and Populations (Randomness and Sampling Bias). 8. Different Samples from the Same Population (Variation, the 'Special Batch', and Standard Error). 9. Confidence and Population Means (Precision and Error Ranges, Student's t, Determining How Large of a Sample Is Needed). 10. Categories and Population Proportions (Percentages Instead of Means) Relationships between Two Variables: 11. Comparing Two Sample Means (The t Test, Results and Interpretations). 12. Comparing Means of More than Two Samples (Relating a Categorical Variable to a Measurement Variable, Analysis of Variance). 13. Comparing Proportions of Different Samples (Relating a Categorical Variable to Another Categorical Variable, Chisquare). 14. Relating a Measurement Variable to Another Measurement Variable. 15. Relating Ranks. 16. Sampling a Population with Subgroups. 17. Sampling a Site or Region with Spatial Units. 18. Sampling without Finding Anything. 19. Sampling and Reality Suggested Reading. Index.
