1. Statistics a set of mathematical procedures for or-
ganizing summarizing and interpreting
information
2. Population the set of all individuals of interest in a
particular study, example- Chinese Amer-
icans over 65
3. Sample A set of individuals selected from a pop-
ulation intended to represent the popu-
lation in a research study, Example 200
Chinese American participants over 65
4. random sample a sample where everyone in a population
has an equal chance of being picked to
better represent a population
5. Variable a characteristic or condition that changes
or has different values for different indi-
viduals
6. Data measurements or observations
7. Data Set a structured collection of measurements
or observations, ex a chart of height and
weight of kittens
8. Datum a single measurement or observation,
commonly called a score or a raw score
9. Parameter a characteristic that describes a popula-
tion, ex the average running speed of an
11 year old male in Virginia

10. statistic A characteristic that describes a sample,
ex the average speed of 30 11 year old
males in a study
11. descriptive statistics statistical procedures used to summarize,
organize, and simplify data, ex averaging
, tables, graphs
12. inferential statistics consist of techniques that allow us to
study samples and then make general-
izations about populations from which
they were selected
13. Representative Sample a sample that reflects general popula-
tion, used in inferential statistics to better
make generalizations about a population
14. sampling error the naturally occurring discrepancy that
exists between a sample statistic and the
corresponding population parameter, ex
a population with an average IQ of 100
but a sample with an average IQ of 107
15. Constructs internal attributes or characteristics that
cannot be directly observed but are use-
ful for describing and explaing behavior,
ex: self esteem or hunger
16. Operational Definition identifies a measurement procedure for
measuring external behavior and used
the resulting measurements as a defini-
tion and a measurement of a hypotheti-
