When should you catagorize data?
After you have collected and examined them.
t-Test
-definition-
A bivariate analysis that examines the differences between the 2 groups by looking at their means while weighing the sampling error
t-Test
-calculation-
Calculation:
Group 1 Mean - Group 2 Mean
----------------------------
Standard error of the difference
Degrees of Freedom
-definition-
A numerical way of expressing how much capacity the data have to vary
Independent-samples t-Test
-definition-
A t-Test used when 2 group are not connected or related to each other in a direct way
Correlated-samples t-Test is also known as....
Paired-Samples t-Test
Correlated-Samples t-Test
-definition-
Compares measurements taken at 2 different points in time from a single group of clients to determine if there is a real difference
Correlated-Samples t-Test is used when measuring...
1)Same group measured 2*
2)Samples are known logically
3)Used to construct a 2nd group that closely resembles the 1st
4)Differences btw. biological twins
5) Pretest Posttest Comparisons of 1 group
One-Sample t-Test
-defintion-

Understand if the groups signficantly vary
4 Questions a researcher should consider with ANOVA
1)Is data measured at interval and are they a random sample of larger populations?
2)Are the groups independent of each other?
3) Are the data normally distributed?
4) Is there approximately the same # of cases in each group?
ANOVA df will equal...
The number of subjects minus 1
Post Hoc Tests is used when...
Used with multiple groups beinig compared and F is signficant
Post Hoc Tests are done when the researcher is investigating...
What contributed to the finding of signficance
Bonferroni Procedure
-definition-
Reduces the problem of finding signficance by dividing the .05 probablity level by the number of statistical tests to be conducted
The Post Hoc procedures minimize what?
Type 1 Error
When should you catagorize data?
After you have collected and examined them.
Paired t-Test are used when you have...
A single (1) group is measured mutliple times
If you have Pre-test, Intervention, and Post-test you use what t-Test?
Paired t-Test
Independent t-Test is used when you have...
2 groups NOT connected in a direct way
Assumptions of T-Tests:
