Statistics Vocab

2. n-1
5. the sampling distribution of the t statistic
11. statistic that provides an estimate of a parameter
12. The parameter is different from the null value but it can be either smaller or larger
13. Measures how far a sample statistic diverges from what we would expect if the null hypothesis H0 were true
17. how close estimate tends be to the parameter
18. the success rate of the method that produces the CI
19. error when null is rejected when it is true
20. two sets of similar data on the same statistic

1. claim we are trying to find evidence to prove
3. acesses data of a claim concerning a population
4. a statement of no difference tested by sig. test
6. calculated from sample data- estimate +/- ME
7. error when there is a failure to reject the null and it is false
8. estimates the amount of standard deviations an element is from mean
9. likelihood of accuracy
10. the STD of a statistic that is estimated from data
14. value used to determine the margin of error
15. The probability that the statistic would take a value as extreme as or more extreme than the one actually observed assuming the null hypothesis is correct
16. The probability that the test will reject H0 at a given α when the specified alternative value of the parameter is true.
