Basic Intro to Statistical Graphs

This type of summary graph is called a

• Histogram

• Dot plot

• Stem and leaf

• Bar graph

Using the data from this stem and leaf plot, which class would have the highest median score

• Class A

• Class B

What is the median score for the date shown in this stem and leaf?

• 85

• 86

• 87

• 28

The mode in the data displayed is

• 20

• 40

• 20 and 40

• 30

What is the distribution of the data?

• skewed right

• skewed left

• symmetric

• stairsteps

The type of summary graph displayed is called

• bar graph or column graph

• histogram

• scatter plot

• line graph

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

Does the distribution of data in this histogram look symmetrical

• yes

• no, it looks pushed to the left

• no, it looks pushed to the right

• no, no pattern eviden

This data looks

• symmetrical

• slightly skewed negative (right)

• slightly skewed positive (left)

The range of the data being shown is;

• 5 degrees F

• 12 months

• 60 degrees F

• 65 degrees F
