Flashcards in Chapter 1 Deck (18):
1

Occurs between two variables if specific values of one variable tend to occur in common with specific values of the other

Association

2

Used to display the distribution of a categorical variable or to compare the sizes of different quantities

Bar graph

3

Places an individual into one of several groups or categories

Categorical variable

4

Describes the values of one variable among individuals who have a specific value of another variable

Conditional distribution

5

A simple graph that shows each data value as a dot above its location on a number line

Dotplot

6

Tell what values a variable takes and how often it takes these values

Distribution

7

Displays the count of observation in each category or class

Frequency table

8

Objects described by a set of data; people, animals, or things

Individuals

9

Drawing conclusions that go beyond the data at hand

Inference

10

One of the categorical variables in a two-way table of counts is the distribution of values of that variable among all individuals described by the table

Marginal distribution

11

Shows the distribution of a categorical variable as a “pie” whose slices are sized by the counts or percents for the categories

Pie chart

12

Takes numerical values for which it makes sense to find an average

Quantitative variable

13

Shows the percents of observations in each category or class

Relative frequency table

14

Used to compare the distribution of a categorical variable in each of several groups. The height of each segment is determined by the percent of individuals in the group with that value, totaling 100%

Segmented bar graph

15

Used to compare the distribution of a categorical variable in each of several groups. The heights of each segment is determined by the count of percent of individuals in the group with that value

Side by side bar graph

16

An association between two variables that holds for each individual value of a third variable can be changes or even reversed when the data for all values of the third variable are combined

Simpson’s paradox

17

A table of counts that organizes data about two categorical variables

Two-way table

18

Any characteristics of an individual. It can take different values for different individuals

Variables
