Across
- 5. the variability we expect to see from one random sample to another
- 6. study based on data in which no manipulation of factors has been employed
- 9. this variable is not immediately evident but impacts the relationship of the variables being studied
- 10. a treatment known to have no effect
- 11. manipulates factor levels to create treatments
- 15. the extent of the interval on either side of the observed statistic
- 17. shows the relationship between two quantitative variables measured on the same cases
- 21. graphs a dot for each case along a single axis
- 22. display consisting of a box between quartiles and "whiskers"
- 24. any systematic failure of a sampling method
- 26. data point that stands away from the others
- 29. recorded values
- 30. what we should conclude if we reject the null hypothesis
Down
- 1. useful family of models for unimodal, symmetric distributions
- 2. difference between observed value and predicted value
- 3. mutually exclusive
- 4. one tail of a distribution stretches farther than the other
- 7. also called a false negative
- 8. also called a false positive
- 12. numerical measure of the direction and strength of a linear association
- 13. if the statistics computed accurately reflect the corresponding population parameters
- 14. the claim being assessed in a hypothesis test
- 16. summary value about a population
- 18. subset of a population
- 19. summary value about a sample
- 20. the probability of observing a value for a particular test statistic
- 23. line of best fit
- 25. entire group whom we hope to learn
- 27. tells how many standard deviations a value is from the mean
- 28. distribution where two halves look approximately like each other
