1. HOMEWORK Due today: P23 19-22
2. Warm-Ups: Multiplication/Division Mixed Numbers
3. P8 Problem 2.1 Modified

OBJECTIVE: 1.4.3 Apply data collection processes to inform, persuade, or answer questions 1.4.4 Understand how variations in data may affect the choice of data analysis techniques used. ACTIVITIES/ASSESSMENT: P8 Problem 2.1 Modified. Design a survey for the class to include 3 categories: After school activities(daily) 1) TV 2)I-Pod/Radio 3) Computer/Game console. Collect the data. make a bar graph, and a circle graph. Express all the possible combinations as ratios and percentages. NOTES: HOMEWORK: P12 6-11

Design a survey for the class to include 3 categories of after school activities (daily)

1. TV
2. I-Pod/Radio
3. Computer/Game console.

Collect the data.

Make a bar graph, and a circle graph of the ‘average’ data. Express all the possible combinations of the ‘averages’ as ratios and percentages

• Data Collection sheet
• Do survey (all classes 1/2/6)
• Analyze data and Target Group (see test/item specs for guidelines
• Do bar graph, line plot, circle graph (pie chart)(show math)
• List ratios and percents (table?)

  Interactive Circle Grapher

OBJECTIVE: 1.4.3 Apply data collection processes to inform, persuade, or answer questions 1.4.4 Understand how variations in data may affect the choice of data analysis techniques used. ACTIVITIES/ASSESSMENT: Set up homework per week project. Develop checklist. Students will need to survey 40 different students. Define average student (sample) NOTES: HOMEWORK: TBA Check-Up 1

Establish new survey: Homework per week project.

Develop a checklist. Students will need to survey 40 different students. Define average student (sample) Review measures of Central Tendency. Time permitting review graphing information.

1. identify or write survey questions that will obtain the appropriate information and will avoid bias.
2. identify or describe how to collect data about a given population, taking into account issues such as the question, collection method, and sample population.
3. describe how a question, data collection method, or population may affect the data.
4. identify, determine, and/or use mean, median, mode, and range as appropriate to describe a set of data.
5. explain the difference between mean, median, and/or mode as a measure of central tendency in a given situation.
6. explain or determine how data added to a data set may affect the  mean, median, mode, and/or range of the data.
7. complete a set of data based on a given mean, median, or mode and a partial set of data.
