a measure whose values are categories that have the properties of being mutually exclusive and not orderable.
What is nominal
100
a statistic that measures the amount of dispersion in a score distribution; it is equal to the difference between the highest and the lowest score plus 1.
What is Range
100
- a type of rank score that represents a given raw score on a measure as the percentage of individual’s in
What is percentile rank
200
a measure whose different values can be placed in order of magnitude, but the difference between any two sets of adjacent values might differ.
What is ordinal
200
a measure of central tendency that identifies the most frequently occurring score in a distribution of scores.
What is mode
200
a statistic that indicates how much a set of scores deviates from the mean score.
What is Standard Deviation
200
Expresses how far a student score is from the mean
What is standard scores
300
- a measure that lacks a true zero point and for which the distance between any two adjacent points is the same.
What is interval
300
The middle score distribution
What is median
300
a statistical measure of the extent to which scores in a distribution deviate from the mean, computed for a sample by dividing the sum of squares by the sample size minus one ( n – 1).
What is Variance
400
a distribution of scores that has the characteristic of being clustered around each side of the mean in a symmetrical bell-shaped curve when plotted on a graph.
What is normal curve
400
most commonly used and tied to the standard deviation
What is z score
500
a quantitative expression of a construct indicating the possible number of ways that individuals or other entities can vary with respect to the construct.
What is a variable
500
a nonsymmetrical distribution of scores in which the majority of scores are clustered on one side of the mean, and the other scores trail off on the other side of the mean.
