Across
- 5. a single value given as an estimate of a parameter of a population
- 6. gives an interval of plausible values for a parameter and is calculated by point estimate-margin of error
- 8. probability distribution that is used to estimate population parameters when the sample size is small and population std is unknown
- 11. cut-off values that define regions where the test statistic is likely to lie
- 12. the difference between true population parameter and a sample estimate of that parameter
- 13. if parameter is different from the null value
- 14. estimate variability and define t-distribution that calculates the p-values for the test
- 15. statistic that provides an estimate of a population parameter
- 17. if we fail to reject the null hypothesis when the alternative hypothesis is true
Down
- 1. measures how far a sample statistic diverges from what we should expect if the null hypothesis were true
- 2. if the p-value is smaller than the alpha
- 3. a statement of no difference
- 4. if the parameter is larger than the null value or states that parameter is smaller than null value
- 7. if we reject the null hypothesis when the null hypothesis is true
- 9. estimate of standard deviation
- 10. the claim about a population we are trying to find evidence for
- 11. gives overall success rate of the method for calculating the confidence interval
- 15. probability if finding the observed or more extreme results when the null hypothesis is true
- 16. probability that the test will reject the null at a chosen significance level alpha when specified alternative value of the parameter is true
