|
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.
|
epistemology
|
|
|
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.
|
level
|
|
|
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.
|
mean
|
|
|
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.
|
parameter
|
|
|
All measurements of a specified group.
|
population
|
|
|
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.
|
sample
|
|
|
A numerical or nominal characteristic of a sample.
|
statistic
|
|
|
One value (or level) of the independent variable.
|
treatment
|
|
|
The top of the range of possible values that a measurement on a quantitative variable can take.
|
upper limit
|
|
|
Something that exists in more than one amount or in more than one form.
|
variable
|
