Age norms |
Norms specifically designed to compare test takers score with those of same age peers |

|
|
Alternate forms reliability |
An estimate of the extent to which items sampling and other errors have affected scores on 2 versions of the same test contrast with parallel forms reliability |

|
|
Bimodial distribution |
A distribution in which the central tendency consists of 2 scores occurring, in an equal number of times that are the most frequently occurring scores in a distribution |
|
|
|
Predictive validity |
An index of the degree to which a test score predicts some criterion or outcome measure in the future. tests are evaluated as to their predictive validity |
|
|
|
Confidence interval |
Confidence intervals range or band of test scores that is likely to contain the true score |

|
Cut score |
Also called cut off score a reference point derived as a result of judgment and used to divide a set of data into 2 or more classifications with some action to be taken or some inference to be made on the basis of these classifications page 9 |

|
|
|
False negative |
It is a specific type of miscaracterized by a tool of assessment indicating that the test taker does not possess or Exhibit A particular trait ability behavior or ultra beauty when in fact the test taker does possess or exhibit this trait ability to behave your attribute |
|
|
|
False positive |
Is an error in measurement characterized by a tool of assessment indicating that the test taker possesses or exhibits a particular trait ability behavior or attribute when in fact the test taker does not |

|
Predictive validity |
A criterion related validity that is index of degree to which a test score predicted some criterion measure |
|
|
|
Range |
A descriptive statistic of variability derived by calculating the difference between the highest and lowest |

|
|
Skewness |
An indication of the nature and extent to which symmetry is absent in distribution skewed positively when few fall in positive and vise versa |

Standard deviation |
A measurement of variability equal to square root of variance |
|
|
|
Standard error measurement |
Statistics designed to estimate the extent to which an observed scoredeviates from true score |
|
|
|
Standard score |
A Raw score that had been converted from one scale into anther, ex z score s and t |
|
|
|
Test-retest reliability |
An estimate of reliability obtained by correlating pairs of scores from same people on different times |
|
|
|
T-score |
Standard score calculation using scale with a mean set at 50 and standard deviation set at 10 |
|
|
|
Z- score |
Standard score derived by calculating differences between particular raw scores and the mean then dividing by standard deviation, express scores in terms of the number of standard deviation that raw score is above or below mean |
