Module 1: Introduction to Probability and Stats
statistics Correct Answer: the science of data; collecting, organizing, classifying, summarizing, analyzing,
presenting, and interpreting numerical information contained in the data
Descriptive Statistics Correct Answer: This application 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 the
information in a convenient form.
Inferential Statistics Correct Answer: This application utilizes sample data to make estimates, decision,
predictions, or other generalizations about a target population.
population Correct Answer: consists of all subjects (human or otherwise) that are being studied.
Examples: all registered voters in Ohio, all students at Miami University, etc.
sample Correct Answer: a group of subjects selected from a population. It is a
subset of the units of a population.
parameter Correct Answer: It is a numerical characteristic of a population. In general; unobservable and
considered a fixed quantity.
statistic Correct Answer: a quantity calculated from data. It is a numerical
characteristic of a sample (a variable quantity).
census Correct Answer: When we study every unit of a population
data Correct Answer: They are recorded values whether numbers or labels with their context
data set Correct Answer: A collection of data values
Data table/spreadsheet Correct Answer: An arrangement of data in which each row represents a case
and each column represents a variable
cases Correct Answer: ndividuals about whom or which we collect some characteristics
respondent Correct Answer: Someone who answers, or responds, a survey
subject Correct Answer: A human experimental unit
experimental unit Correct Answer: An individual (animal, plant, website, etc.) in a study for which or
for whom data values are recorded.
variable Correct Answer: a characteristic or property of an experimental unit
