What types of data displays do you know?
G
Let's recall the types of data displays we can use to describe a data set.
| Data Display | When Do We Use It? |
|---|---|
| Pictograph | To show data using pictures |
| Dot Plot | To show the number of times each value occurs in a data set |
| Stem-and-Leaf Plot | To show how ordered numerical data are distributed |
| Box-and-Whisker Plot | To show the variability of a data set by using quartiles |
| Circle Graph | To show data as parts of a whole |
| Bar Graph | To show frequencies of data values in specific categories |
| Histogram | To show frequencies of data values in intervals of the same size |
| Line Graph | To show how data change over time |
| Scatter Plot | To show the relationship between two data sets using ordered pairs plotted in a coordinate plane |

The director of a research lab wants to present data to donors. The data show how the lab uses a large amount of donated money for research and only a small amount of money for other expenses. |
In other words, the director wants to show that other expenses
are a very small part of the whole amount of donated money. Therefore, a circle graph seems to be the best option and answer G is correct. The circle graph for this situation might look something like this.
