stats 2-4

Question 1

STATS 2-4

scatter plot

Answer 1

the ordered pairs are graphed as points in a coordinate plane; x on horizontal axis, y on vertical axis. used to show the relationship between two quantitative variables

Question 2

STATS 2-4

Time-series graph

Answer 2

Graph of quantitative data that have been collected at different points in time such as hourly, weekly or monthly

Question 3

STATS 2-4

dot plot

Answer 3

a graph in which each data value is plotted as a point or dot along a horizontal scale of values.

Question 4

STATS 2-4

stemplot

Answer 4

represents quantitative data by separating each value into two parts: the stem (the left most value) and the leaf (the right most digit.) stemplots are a good way to sort data.

Question 5

STATS 2-4

bar graph

Answer 5

uses bars of equal width to show frequencies of categories of categorical (qualitative) data.
vertical scale shows frequencies or relative frequencies. The horizontal scale shows different qualitative data.

Question 6

STATS 2-4

multiple bar graph

Answer 6

has 2 or more sets of bars and is used to compare 2 or more data sets.

Question 7

STATS 2-4

pie chart

Answer 7

graph that depicts categorical data as slices of a circle in which the size of each slice is proportional to the frequency count for that category.

Question 8

STATS 2-4

frequency polygon

Answer 8

uses line segments connected to points directly above class midpoint values.

Question 9

STATS 2-4

Ogive

Answer 9

depicts cumulative frequencies. An Ogive uses class boundaries along the horizontal scale and cumulative frequencies along the vertical scale.

Question 10

STATS 2-4

Non zero axis

Answer 10

bad graph, can make graph decieving

Question 11

STATS 2-4

pictographs

Answer 11

often misleading because data that are one dimensional are shown in a 2 dimensional or three dimensional images, such as dollar bills, money bags, or coins.
