Description

One-Way Anova Null and Alternative

null

Alternative

One-Way Anova on Calculator: F3, F5

F Critical: F5, F4, F3 N:df = among group’s df D:df= within groups df Turkey- Kramer: When p-value is less than ___ you can conclude that there is significant difference (yes) When p-value is greater than, it’s a no

Chi-Square Tests Difference between 2 proportion X^2 critical value: F5, F3, F3 DF is always 1 for difference between 2 Chi-Square Tests on calc: F3,F3,F2 (2way)

2 Sample t-test: F3,F2,F2 (pool on)

T Critical value: F5,F2,F3 Area= divide by 2 for 2 tail test Df= n+n-2 Separate Variance T test – F3, F2, F2 Pooled off= Separate Variance

Confidence Interval estimate: F4

Pooled On= Pooled Variance Paired T-test: Calculate difference first (subtract the 2 numbers) F3, F2, F1 (Put the difference on a list) T Critical: F5, F2, F3 Area= divide by 2 Df= n-1

T-Test vs Z-Test vs F-Test T-Test: difference in the means of 2 independent populations Z-Test: Difference between 2 proportions F-Test: Difference between 2 variances

Z test hypothesis for proportion: F3, F1, F4

Z Critical Value: F5,F1,F3 Sd:1 symbol below that is 0

Z test for difference between 2 proportions

F Critical: F5, F4, F3 2 Sample F-test: F3, F4...
