Inferential Statistics
The property of moreness
Magnitude
The difference between two points at any place on the scale has the same meaning as the difference between two other points that differ by the same number of scale
Equal intervals
When nothing of the property being measured exists
Absolute 0
A set of numbers who properties model empirical properties of the objects to which the numbers are assigned
Scale
Takes on any value within the range and the possible value within that range is infinite
Continuous scale
Can be counted, has distinct, countable values
Discrete scale
Refers to the collective influence of all the factors on a test score or measurement beyond those specifically measured by the test or measurement
Measurement with continuous scale always involve with error
Error
Involve classification or categorization based on one or more distinguishing characteristics
Nominal
Rank ordering on some characteristics is also permissible
Ordinal
Contains equal intervals, has no absolute zero point (even negative values have interpretation to it)
Interval
Has true zero point( if the score is zero, it means none/null)
Ratio
Defined as a set of test scores arrayed for recording or study
Distribution
