Tobi asked his classmates about their favorite season. This information is called data. Here is the data Tobi recorded:

table of 25 data points

Let’s help Tobi organize this data. This is a tally chart. One tally mark represents one person’s vote for the wet season or dry season.

Favorite Seasons: Dry Season: 0. Wet Season: 0.

How many students like the dry season?

Table of favorite seasons. 18 suns highlighted.

How many students like the wet season?

Table of favorite seasons. 7 rain drops highlighted.

We can use the tally chart to create a pictograph. A pictograph is a graph that uses pictures to show numbers.

This is the pictograph that Tobi will use:

Table of favorite seasons. Dry Season: 0. Wet Season: 0.

18 students like the dry season. Each star represents 2 students, so we will place 9 stars in the pictograph.

7 students like the wet season. Since each star represents 2 students, we will put 3 and a half stars in the pictograph.

We can use this pictograph to compare Tobi’s data. How many more students like the dry season than the wet season?

Table of favorite seasons. Each star is equal to 2 students. Dry Season: 9 stars. Wet Season: 3.5 stars. 18 - 7 = ___

Let’s compare this data using subtraction.
