Across
- 2. describes some characteristic of a population
- 5. Claim we weight evidence against in a significance test. Often a statement of “no difference.”
- 7. Specific value of a point estimator from a sample
- 8. Occurs if we reject H0 when H0 is true.
- 11. When the standard deviation of a statistic is estimated from data
- 12. is an interval that is computed from sample data and provides a range of plausible values for a population parameter.
- 14. The claim that we are trying to find evidence for in a significance test
- 16. Gives the probability of a Type I error.
- 17. depends on both the confidence level C and the sampling distribution of the statistic
- 19. Statistic that provides an estimate of a population parameter
- 20. Calculation that measures how far a sample statistic diverges from what we would expect if the null hypothesis H0 were true, in standardized units
Down
- 1. if the alternative hypothesis states that the parameter is different from the null value
- 3. Occurs if we fail to reject H0 when Ha is true
- 4. Success rate of the method for calculating the confidence interval
- 6. The probability that a test will reject H0 at a chosen significance level α when a specified alternative value of the parameter is true
- 9. The probability, computed assuming H0 is true, that the statistic would take a value more extreme than the one actually observed
- 10. The difference between the point estimate and the true parameter value will be less than this
- 13. n-1
- 15. Procedure for using observed data to decide between two competing claims
- 18. Table which shows probabilities under a normal curve, which can be used to derive z* the critical value
