I'm a Stat Brat

4. a hypothesis that states the parameter is different from the null hypothesis value
8. claim about the population we are trying to find evidence for
9. state, plan, do, conclude
11. usually set as .05
12. an error committed when we reject the null when the null is true
15. probability that the test will reject the null at a chosen significance level, alpha, when the specified alternate value of the parameter is true
16. an interval that takes the form estimate (+/-) margin of error
19. often a statement of "no difference"
20. tells us how close the estimate tends to be to the unknown parameter in repeated sampling

1. results when a standard deviation is estimated from the data
2. occurs if the probability calculations involved in the procedure remain fairly accurate when a condition is violated
3. found by calculating (n-1)
5. where you interpret you interval in the context of the problem
6. an example would be a proportion or mean
7. a hypothesis that states the null as larger or smaller than the null value
10. point(s)on the scale of the test statistic beyond which we reject the null hypothesis
13. statistic that provides an estimate of a population parameter
14. the overall success rate of the method for calculating confidence interval
17. the probability that the statistic would take a value as extreme as or more extreme than the one actually observed
18. an error committed when we fail to reject the null when the null is false
