1. Open your agenda to your Behavior Card.
2. Put Computation Challenge graph under “Work in Progress” and plot your score.
3. Take out “Rolling Out a Stem and Leaf Plot” activity. Finish constructing your stem and leaf and answering the questions. Turn into the tray. Make sure your name is on it!
4. Set up two pages for Cornell Notes.

What am I Learning Today?
Bar graphs
Histograms
How will I show that I learned it?
Compare and Contrast bar graphs and histograms using a Venn Diagram.
Create and analyze a histogram.

VocabularyBar Graph: Graph that uses bars to display
and compare data in separate categories.
Histogram: A bar graph that shows the number of data items that occur within each interval.
Scale: A series of numbers that includes all the data values
Interval: Separates the scale into equal parts

BAR GRAPH HISTOGRAM
both
- Bars are separated and equally spaced apart
- Can display categorical and numerical data
- Bars touch
- Can display only numerical data
- Uses intervals
- Have a title and labels
- Use a scale
- Use bars

Questions Answers
What do all graphs have in common?
Title, axes labels, and a scale
What is the purpose of a histogram?
Show frequency of occurrences within each interval
What kind of data is best suited for a
histogram?
Mostly large sets of numerical data
What is the purpose of a bar graph? Compare quantities in different categories
What kind of data is best suited for a bar
graph?
Mostly categorical data that can be compared individually, but numerical data can also be represented in this way.
Can a histogram have intervals of 0-5, 5-10,
10-15?
No; intervals cannot share a value and must include the same amount of data

Group Discussion
1. What scale was used? Why?
2. How many data values are in each interval?
3. What conclusions can you draw from this graph? Explain.

Helpful Hints for Constructing a Histogram
• Make sure the bars are all the same width• All intervals must be used, even if there
was no data collected• Choose an appropriate scale according to
your frequencies• Label the axes accurately (what does the
information describe)• Use a ruler for neat work
