|
Constant (p. 6)
|
A quantity whose value doesn’t change. Pi is an example; it has a value that never changes. The value of Pi to 5 decimal place accuracy is 3.14159.
|
|
|
Correlational studies (p. 9)
|
In correlational research, the investigator focuses attention on two or more variables to determine whether they are related
|
|
|
Data (p. 7)
|
The measurements that are made on the subjects of an experiment are called data.
|
|
|
Dependent variable (p. 7)
|
The dependent variable in an experiment is the variable that the investigator measures to determine the effect of the independent variable.
|
|
|
Descriptive statistics (p. 10)
|
concerned with techniques that are used to describe or characterize the obtained data.
|
|
|
Independent variable (p. 6)
|
the variable that is systematically manipulated by the investigator.
|
|
|
Inferential statistics (p. 10)
|
involves techniques that use the obtained sample data to infer to populations.
|
|
|
Method of authority (p. 4)
|
to consider something true because of tradition or because some person of distinction says it is true.
|
|
|
Method of intuition (p. 5)
|
sudden insight; the clarifying idea that springs into consciousness all at once as a whole. It is not arrived at by reason
|
|
|
Method of rationalism (p. 4)
|
uses reasoning alone to arrive at knowledge.
|
|
|
Naturalistic observation research (p. 9)
|
With naturalistic observation research, a major goal is to obtain an accurate description of the situation being studied.
|
|
|
Observational studies (p. 9)
|
In this type of research, no variables are actively manipulated by the investigator, and hence observational studies cannot determine causality.
|
|
|
Parameter (p. 7)
|
A parameter is a number calculated on population data that quantifies a characteristic of the population.
|
|
|
Parameter estimation research (p. 9)
|
Parameter estimation research is conducted on samples to estimate the level of one or more population characteristics (e.g., the population average or percentage).
|
|
|
Population (p. 6)
|
A population is the complete set of individuals, objects, or scores that the investigator is interested in studying.
|
|
|
Sample (p. 6)
|
A sample is a subset of the population.
|
|
|
Scientific c method (p. 6)
|
The scientist has a hypothesis about some feature of realty that he or she wishes to test. An objective, observational study or experiment is carried out. The data is analyzed statistically, and conclusions are drawn either supporting or rejecting the hypothesis.
|
|
|
SPSS (p. 11)
|
SPSS is the most popular statistical software program used in psychology
|
|
|
Statistic (p. 7)
|
A statistic is a number calculated on sample data that quantifies a characteristic of the sample.
|
|
|
True experiment (p. 9)
|
In this type of research, an attempt is made to determine whether changes in one variable cause* changes in another variable. In a true experiment, an independent variable is manipulated and its effect on some dependent variable is studied.
|
|
|
Variable (p. 6)
|
A variable is any property or characteristic of some event, object, or person that may have different values at different times depending on the conditions.
