Statistics vocabulary terms chapter 8-9
Across
- 6. the confidence interval is sometimes referred to this
- 8. a formal procedure for using observed data to decide between two competing claims
- 11. of we reject Ho when Ho is true
- 12. if we fail to reject Ho when Ha is true
- 14. if the p-value is smaller than alpha
- 16. probability of getting a sample result at least as extreme as the one we did if the null hypothesis were true
- 17. the claim we weigh evidence against in a statistical test
- 19. A statistic that provides an estimate of a popular parameter
- 20. the alternative hypothesis is this if it states that a parameter is larger than the null hypothesis value or if it states that the parameter smaller than the null value
Down
- 1. The value of the point estimator from a sample
- 2. if the alternative hypothesis states the parameter is different from the null hypothesis value (could be either larger or smaller)
- 3. when conditions are met, a C% confidence interval for the mean is given by this
- 4. the difference between the point estimate and the true parameter will be less than this C% of all samples
- 5. error this error results when the standard deviation of a statistic is estimated from data
- 7. where Sx is the sample standard deviation. It describes how far X will typically be from M in repeated SRSs of size n
- 9. gives the overall success rate of the method for calculating the confidence interval
- 10. Gives an interval of plausible values for a parameter
- 13. the claim about the population that we are trying to find evidence for
- 15. the distribution for every positive degrees of freedom
- 18. if the p-value is greater than or equal to a and say that we do not have convincing evidence for Ha
