Confidence Intervals and Significance Tests
Across
- 2. failing to reject null when null is false
- 5. a statistic that provides an estimate of a population parameter
- 9. the curve always used when finding the confidence interval of a mean
- 13. The probability that something more extreme than a value, given that the null is true, will happen.
- 14. n-1, used in t distributions when sampling distribution is close to normal
- 15. what we say when p value is less than alpha
- 18. value of a statistic from a sample
- 20. when probability calculations involved the procedure remain fairly accurate when a condition is violated
Down
- 1. standard deviation divided by the square root of the sample size
- 3. rejecting null when null is true
- 4. how close the estimate will be to an unknown parameter in repeated testing
- 6. Claim about population we are trying to find evidence for
- 7. the z-score used to find the interval
- 8. A formal procedure for comparing observed data with a claim whose truth we want to assess
- 10. Claim tested by a statistical test
- 11. "a proportion of all possible samples of a given size from this population will result in an interval that captures the unknown parameter
- 12. when the alternative hypothesis states that a parameter larger than or less than the null value
- 16. "We are C% that the interval from __ to __ captures the actual value of the [population parameter in context]
- 17. probability that a test will reject null at a chosen significance level if the parameter is true
- 19. when the alternative hypothesis states that a parameter is different from the null
