standard error of measurement
|
an estimate of error to use in interpreting an individual’s test score
|
|
|
standard error of the estimate`
|
If all the errors of prediction are computed, these would comprise a distribution of error in prediction. This distribution has a standard deviation, called the standard error of estimate.
|
|
|
standard error of the statistic
|
the standard deviaton of the sampling distribution of the statistic
|
|
|
squared correlation coefficient
|
The squared correlation coefficient (r2) is the proportion of variance in Y that can be accounted for by knowing X. Conversely, it is the proportion of variance in X that can be accounted for by knowing Y.
|
|
|
base rate
|
generally refers to the (base) class probabilities unconditioned on featural evidence, frequently also known as prior probabilities
|
|
|
effect of the test length on validity
|
if you increase the test length of a test, the reliability of the test increases
|
|
|
multiple regression (correlation)
|
is a correlation between one dependent variable and a set of independent variables.
|
|
|
false negative
|
In classification, diagnosis, or selection, an error in which an individual is assessed or predicted not to meet the criteria for inclusion in a particular group but in truth does (or would) meet these criteria.
|
|
|
false positive
|
In classification, diagnoses, or selection, an error in which an individual is assessed or predicted to meet the criteria for inclusion in a particular group but in truth does not (or would not) meet these criteria.
|
|
|
true positive
|
In classification, diagnoses, or selection, an individual is assessed or predicted to meet the criteria for inclusion in a particular group when individuals indeed meet these criteria
|
|
|
true negative
|
In classification, diagnosis, or selection, an individual is assessed or predicted not to meet the criteria for inclusion in a particular group when indeed individuals do not meet these criteria.
|
|
|
scales of measurement
|
the 4 scales of measurement comprise a hierarchy of measurement levels based on the amount of information contained in the score or the measure generated by the scales.
ex. nominal, ordinal, interval, and ratio |
