Significance |
Practical, Statistical, Theoretical |
|
|
Practical |
Can be assessed by using, e.g. average functioning of a non-problematic peer group and/or subjective impressions by client and/or cultural norms |
|
|
Statistical |
Prove or disprove the null hypothesis (no change). Type 1 and 2 errors |
|
|
Type 1 error |
Rejecting the null hypothesis when it is true; saying there is change when there is not |
|
|
Type 2 error |
Not rejecting the null hypothesis when it is not true; saying there is no change when there is |
|
|
Theoretical |
Results correspond with theoretical expectations |
|
|
Level
Terms of Analysis |
Magnitude of variables as indicated by the data at any point |
|
|
Discontinuity
Terms of Analysis |
Change in level between the baseline and intervention phase |
|
|
Stability
Terms of Analysis |
Predictability from one period to the next |
|
|
Trend or Directionality
Terms of Analysis |
1. Slope is trend within a phase
2. Drift is a trend across phases |
|
|
Alignment
Terms of Analysis |
When all graphs considered together have essentially the same pattern of improvement, no change, or deterioration |
