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
