Comparing Data in Different Graphs

A _______ is a graphic display using a simple scale to compare the frequency within categories or groups.

• Histogram

• Line Graph

• Box Plot

• Dot Plot

You could change the intervals of the _____ to see which gives a better description of the data.

• Histogram

• Dot Plot

• Line Graph

• Box Plot

What type of Data Display is this?

• Line Graph

• Histogram

• Scatter Plot

• Bar Graph

Bar graphs are a good data display because...

• They make comparisons between different variables very easy to see.

• They are good at showing specific values of data, meaning that given one variable the other can easily be determined.

Scatter plots are a good data display because...

• They show the percentage of the whole data set.

• They allow you to see a correlation from a set of imperfect data points.

Which type of chart is best suited for comparing different categories of data?

• bar chart

• scatter plot

• pie chart

• line chart

Under what circumstances are bar graphs particularly useful?

• If you don't understand how a pie graph works

• When you need to compare 2 or 3 independent variables on the same graph

• When very few of the data values repeat

• Pie graphs are always more useful.

Sometimes, pie graphs are difficult to create.  Also, comparing 2 different groups with pie graphs isn't ideal.  The differences are difficult to see.  What is the alternative to a pie graph?

• Box and Whisker graph

• Dot Plot

• Histogram

• Segmented Bar chart

What type of graph is this?

• Dot Plot

• Bar Graph

• Stem and Leaf Plot

• Scatter Plot

This is an example of a:

• dot plot

• bar graph

• scatterplot

• stem + leaf plot
