|
A person, place or thing from which data can be gathered
|
Subject
|
|
|
All subjects of interest
|
Population
|
|
|
A subset of a population
|
Sample
|
|
|
A value that summarizes information about a sample
|
Statistic
|
|
|
A value that summarizes information about a population
|
Parameter
|
|
|
The science of characterizing and describing the sample and inferring, on this bias, what is happening in the population
|
STATISTICS
|
|
|
Property or characteristic held by items in a population that may vary across the population
|
Variable
|
|
|
When outcomes simply specify the group the subject belongs to (numerical only as a coding device)
|
Categorical Variable
|
|
|
When the outcomes must be expressed as numbers through counting or measuring
|
Numerical Variable
|
|
|
NO outcomes between consecutive outcomes
|
Discrete numerical
|
|
|
INFINITE numbers between 2 outcomes
|
Continuous Numerical
|
|
|
Numerical values are substituted for group names for a categorical variable.
|
Coded Variable
|
|
|
A subject's numerical value for some variable
|
Score
|
|
|
The set of outcomes and scores for all variables of all subjects
|
Data
|
|
|
a variable is generally set or manipulated by the researcher
|
Independent Variable
|
|
|
A variable whose variable is generally set or manipulated by the researcher
|
Independent Variable
|
|
|
Variable measured by the researcher as the focus of the study (often one wants to know the effect the independent variable has on the dependent variable)
|
Dependent Vairable
|
|
|
When each sample of a given size has the same chance of being chose.
|
Simple Random Sampling
|
|
|
The researcher does not APPLY values for the independent variables, but may select on the basis. The values of the DV already exist but need to be collected.
|
Obersvational Study
|
|
|
The method of producing data as a consequence of applying values for the independent variable. The DV is produced for the purpose of the study
|
Experiment
|
