Throughout your life, you have taken a number of tests or handed in assignments on a wide variety of topics. For instance, you might have taken a test to get your driver’s licence, to prove your knowledge of a subject in a class at school, or to become a certified scuba diver. Your marks on these tests may have been compared against your previous marks or against marks of other students. Not only are these comparisons used to evaluate the success of individual students and classes, but they can also be used to evaluate whether the test or specific assignment was a good measure of student success.

 

In this lesson you will investigate different tools that can be used to organize and summarize data so that data can be interpreted or compared.

 

This lesson will help you answer the following critical question:

  • How can data be organized and summarized so the results can be compared?
Time
 

Each module is made up of lessons. Each lesson in Mathematics 20-2 is designed to be completed in approximately 80 minutes. You may find that you require more or less time to complete different lessons depending on your strengths. It is important that you progress at your own pace based on your individual learning requirements.

 

Assessment
 

All assessment items you encounter need to be placed in your course folder.

 

There are no marked assessment items for Lesson 1. While you will not be handing in any work from Lesson 1 for marking, the activities in this lesson will prepare you for other assignments in this module.

 

For those items that you will not be handing in for marking, you should have already had a discussion with your teacher about how you can access the solutions to these questions. Make sure to follow your teacher’s instructions.

 

This lesson provides you with opportunities to investigate, discuss, and practise the knowledge and skills you are learning. For instance, in a Share activity, you can check your answers with other students to see if you are on track. If you are having difficulty with concepts or calculations, contact your teacher.
