Math A30 Data Analysis (WEB 2.0)

Subject: Math A30
Unit: Data Analysis
Objectives: Evergreen Curriculum
B.1
To list and describe the methods used to collect data.
B.2
To obtain data for real-world situations by using simulations (such as Monte Carlo simulations).
B.3
To review the methods for determining the measures of central tendency.
B.4
To construct box and whisker plots from simulated data.
B.5
To define and utilize the concept of percentiles (including the first, second, and third quartiles).
B.6
To solve related problems using statistical inference.

Website: Stellar Survey

This website allows you to create a free online survey. You can create multiple choice questions, rating scales, short answers etc. (25 types of questions). Once you've created your survey you can create a link to your survey that you could post on a website or e-mail to other people in order to collect your data. Then they have a variety of resources that help you to display your data and interpret it.

When I saw this website Math A30 Data analysis came to mind. I would use this website as a method that students can use to collect data that they will interpret. One of the curriculum objectives in this unit is to collect data from real world situations by using simulations. Students could create their very own survey in each their peers will answer. Once they have collected their data I would have them construct box and whisker plots as well as demonstrate the first, second and third quartiles.

One key fact to tell students when they creating their own survey is that it must be numerical data for example How many siblings do you have? compared to What color of pen do you prefer to use? The question the students will be surveying will need to quantitative not qualitative.

I would use this as an overall project for this unit. Incorporating objectives as they arise in each lesson.

I'm excited to give this a try. I'll post again if I do to let you know how it goes.

I think students would benefit from it because it reaches a lot of the Common Essential Learnings found in the curriculum such as:

• Communication; using e-mail to communicate or a website
• Numeracy; understanding the quantitative data collection
• Critical and Creative Thinking; students can create their own survey about a topic that interests them. Critical thinking will occur curing interpreting the data.
• Technological Literacy; Reading the website as well as understanding how to navigate and use the website
• Personal and Social Values and Skills; Students can personalize their survey and incorporate an investigation about what is important to them
• Independent Learning. Students must create their own survey and interpret their own data. As an extra depending on the topics they chose they research what the percentages are if it was a world survey.
