Independent Models For Interval Data
|
| Model |
Uses |
 |
One set of data, placement of an
additional score in question |
 |
One set of data, likelihood of being part of
a hypothetical population in question |
 |
Two groups, one measure, population variances assumed equal
Exp Pre vs. Con I Pre,
Exp Post vs. Con I Post,
Exp Post vs. Con II Post
Con I Post vs. Con II Post |
 |
Two groups, one measure, population variances assumed not equal
Exp Pre vs. Con I Pre,
Exp Post vs. Con I Post,
Exp Post vs. Con II Post
Con I Post vs. Con II Post |
 |
Three or more groups, one measure, population variances assumed equal
Exp Post vs. Con I Post vs. Con II Post |
|
Related Models For Interval Data
