Scales
An interval scale with the additional features of an absolute zero point.
Ratio Scale
Measurements or observations.
Data
The variable that is manipulated by the researcher.
Independent Variable
A value, usually a numerical value, that describes a sample
Statistic
Ordered categories that are all intervals of exactly the same size. Equal differences between numbers on the scale reflect equal differences in magnitude.
Interval Scale
A collection of measurements or observations.
Data Sets
The one that is being observed to assess the effect of the treatment.
Dependent Variable
Statistical procedures used to summarize, organize and simplify data.
Descriptive Statistics
Consists of a set of categories that are organized in an ordered sequence. Rank observations in terms of size or magnitude.
Ordinal Scale
A value, usually a numerical value, that describes a population.
Parameter
There are an infinite number of possible values that fall between any two observed values.
Techniques that allow us to study samples and then make generalizations about the population from where they were selected.
Inferential Statistics
Consists of a set of categories that have different names- measurements label and categorize observations, but do not make any quantitative distinctions between observations.
Nominal Scale
Consists of separate, indivisible categories. No values can exist between two neighboring categories.
Discrete Variable
