|
Specificity
|
Rule in Dx, ability of test to show negative when truly negative D/(B+D)
High true negative, low false positive |
|
|
Sensitivity
|
Used to rule out condition.
Ability of test to show positive when truly positive A/(A+C) High True positive, low false negatives |
|
|
kappa value
|
percent of agreement beyond chance of nominal data
|
|
|
reliability
|
consistent reproducibility
Intratester - same tester different occaisions Intertester - between different testers |
|
|
minimum clinically important difference
|
1. statistical calculation for comparison

|
|
minimum detectable change
|
statistical calculation that takes into account reliability and measurement errors
ammount of change to exceed the threshold of error |

|
+LR
|
how much the odds of the Dz increase (post test probability) when test is positive
|
|
|
Correlation
|
association between variables, doesn't address actual values or agreement
|
|
|
Agreement
|
are scores the same and show actual values
|
|
|

|
-memorize solution to specifoc problem
-identify problem with surface elements -problems to difficult to solve -don't think of best way to solve problem, just plow through -don't consider connections of subsequent problems |
|
|
Expert
|
-believe most problems can be solved through only a few central principles
- identfy problem through principles of solution - confident to solve problems - evaluate thinking -after problem solving, how does it relate to..... |
