Parameter - CORRECT ANSWER-numerical quantities that describe probability distributions. a
numerical descriptive measure of a population
Sample Statistic - CORRECT ANSWER-a numerical descriptive measure of a sample. It is
calculated from the observations in the sample.
Statistics - CORRECT ANSWER-the science of data. this involves collecting, classifying,
summarizing, organizing, analyzing, presenting & interpreting numerical & categorical
information.
two types of statistical applications - CORRECT ANSWER-descriptive & inferential statistics
Descriptive Statistics - CORRECT ANSWER-Utilizes numerical and graphical methods to look for
patterns in a data set, to summarize the information revealed in a data set, and to present that
information in a convenient form.
inferential statistics - CORRECT ANSWER-utilizes sample data to make estimates, decisions,
predictions, or other generalizations about a larger set of data
, population - CORRECT ANSWER-is a set of all units (usually people, objects, transactions, or
events) that we are interested in studying
sample - CORRECT ANSWER-is a subset of the units of a population
variable - CORRECT ANSWER-is a characteristic or property of an individual experimental (or
observational) unit in the population
experimental (or observational) unit - CORRECT ANSWER-is an object (e.g., person, thing,
transaction, or event) about which we collect data.
statistical inference - CORRECT ANSWER-is an estimate, prediction, or some other generalization
about a population based on information contained in a sample
measure of reliability - CORRECT ANSWER-is a statement (usually quantitative) about the
degree of uncertainty associated with a statistical inference.
Four Elements of Descriptive Statistical Problems - CORRECT ANSWER-1. The population or
sample of interest
2. One or more variables (characteristics of the population or sample units) that are to be
investigated
3. Tables, graphs, or numerical summary tools
4. Identification of patterns in the data.
Five Elements of Inferential Statistical Problems - CORRECT ANSWER-1. The population of
interest
2. One or more variables that are to be investigated
3. The sample of population units
4. The inference about the population based on information contained in the sample
