Flashcards in Chapter 1 Deck (19):

1

## Used to compare the distribution of a quantitative variable for two groups

### Back-to-back stemplot

2

## A graph of a five-number summary

### Boxplot

3

## A process of describing data using graphs and numerical summaries

### Data analysis

4

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

### Dotplot

5

## Minimum Q1 Medium Q3 Maximum

### The five-number summary

6

## Displays the distribution of a quantitative variable. The base of the bar covers the class, and the bar height is the class frequency or relative frequency

### Histogram

7

## IQR=Q3 - Q1

### Interquartile range

8

## The arithmetic average

### Mean

9

## The midpoint if a distribution, the number such that half the observation are smaller and the other half are larger

### Median

10

## The value or class in a statistical distribution have the greatest frequency

### Mode

11

## An individual value that falls outside the overall pattern of a distribution

### Outlier

12

## Shape, center, spread, outlier

### Overall pattern

13

## a set of quantitative data that is the (maximum value) minus the (minimum value)

### Range

14

## A statistic that is not affected very much by extreme observations

### Resistant measure

15

## Measures the average distance of the observations from their mean

### Standard deviation (Sx)

16

## If the right and left sides of a graph are approximately mirror images of each other

### Symmetry

17

## Standard deviation squared

### Variance Sx^2

18

### Lower outlier
