Reading Statistical Graphs

This type of summary graph is called a

• Histogram
• Dot plot
• Stem and leaf
• Bar graph

Using the data from this double stem and leaf plot, what is the minimum and maximum value for each class

• Class A: min = 86 max = 100; Class B: min = 60 max = 92

• Class A: min = 68 max = 100; Class B: min = 60 max = 92

• Class A: min = 80 max = 96; Class B: min = 60 max = 92

How many students scored 87% on the test?

• 0

• 1

• 2

• Unable to determine

The type of summary graph displayed is

• column graph

• bar graph

• dot plot

• scatter graph

The mode is the number that occurs the most. What is the mode in the data?

• 20

• 40

• 20 and 40

• 30

What type of statistical distribution is represented?

• normal

• not normal

The type of summary graph displayed is called

• bar graph or column graph
• histogram
• scatter plot
• line graph

Range is the difference between the maximum and minimum value. The range of the data being shown is;

• 5 degrees F

• 12 months

• 60 degrees F

• 65 degrees F

You can determine a histogram from a bar graph as

• histograms have spaced between the columns, bar graphs do not
• histograms do not have any spaced between the columns, bar graph do

The distribution of the data shown is symmetrical because

• the shape looks even on both sides

• you can see a pattern where most of the data is in the middle

• the distribution forms a nice bell curve

• all responses correct
