Holt R., Holt W. Picturing Numbers: Data Analysis and Probability

Encyclopædia Britannica, 2006. - 56 pages. ISBN: 003042402XDear Student, Can you picture numbers? Sometimes a picture of the numbers in a problem makes things easier to understand. In this unit, you will discover different ways to picture numbers. Pictures can help you tell a story about numbers and about what they represent such as fliers delivered, fuel in a tank gauges, and TV programs preferred.
You will look at bar graphs and number line plots. You will make a picture called a line graph to show
how temperatures change from one time interval to the next.
You will create charts that look like pies to describe the results of your own surveys. You will also begin to describe a distribution of data by some summary numbers—such as the maximum, the minimum, the mean, and the mode. You will learn how to think about the word average as the mean of a set of numbers.
In the end, you should understand something about how pictures can describe numbers and what types of pictures can help you understand different situations.
