The observed variable that is expected to change as a result of changes in the independent variable in an experiment.
dependent variable
A number that conveys a particular characteristic of a set of data.
descriptive statistic
The study or theory of the nature of knowledge.
Variable other than the independent variable that may affect the dependent variable.
extraneous variable
Variable controlled by the researcher; changes in this variable may produce changes in the dependent variable.
independent variable
Method of reaching conclusions about unmeasurable populations that uses sample evidence and probability.
inferential statistics
Measurement scale in which equal differences between numbers represent equal differences in the thing measured. The zero point is arbitrarily defined.
interval scale
One value of the independent variable.
Bottom of the range of possible values that a measurement on a quantitative variable can take.
lower limit
Arithmetic average; sum of scores divided by number of scores.
Measurement scale in which numbers serve only as labels and do not indicate any quantitative relationship.
nominal scale
Measurement scale in which numbers are ranks; equal differences between numbers do not represent equal differences between the things measured.
ordinal scale
Numerical or nominal characteristic of a population.
All measurements of a specified group.
Variable whose levels are different kinds, not different amounts.
qualitative variable
Variable whose levels indicate different amounts.
quantitative variable
Measurement scale with characteristics of interval scale; plus zero means that none of the things measured is present.
ratio scale
A subset of a population that may or may not be representative.
A numerical or nominal characteristic of a sample.
One value (or level) of the independent variable.
The top of the range of possible values that a measurement on a quantitative variable can take.
upper limit
