YOUR TASK: 1. To learn how to create and interpret circle graphs so that you can investigate the relationship between physical and sedentary activities in Canadian children. 2. To learn how to create and interpret scatter plots so you can prove, or disprove, the Vitruvian theory using data compiled from Canadian students, LIKE YOU! :)
THE PROCESS: Follow the posts, in sequence, as you navigate through various websites while you create, describe, interpret, and LEARN! Be sure to work your way through the post IN ORDER so you do not miss any important information. HAVE FUN!

STEP 3: INTERPRETING A CIRCLE GRAPH -- PART 2

There are other ways in which you can INTERPRET a circle graph. You can make PREDICTIONS based on the percentage of each sector. For example, in the previous webpage accessed in the last post (click HERE), example 1 looked at the music preferences of students at Adams School (see graph below). If the school had a population of 500, you could predict approximately how many students preferred "rap" music based on the sector percent given.

Example:
35% of 500
= 0.35 x 500
= 175

THEREFORE, 175 students prefer rap music.

Using the graph above, predict how many students, out of 500, prefer "country" and "rock and roll" music (calculate each separately). Solve, showing your work/calculations, and email me your answers (see profile for email address). Be sure to include the name of this post as your subject.
