Math 9 – Unit 9 Statistics and Probability

Grade 9: Pick- A- Project

Objective: You will develop, collect, display, and analyze data from a topic of your choice.

Procedure:

Did you decide what topic you want to base your project on? Be sure your topic can:

o Can fit into a list or have a variety of options to answer it. For example: Favourite sports,

favourite foods, age you first dyed your hair, most disgusting food, ect.

o Is relevant to people in our school

o Develop a “surveyable” question from your topic with a limited of responses (hint: you

will be conducting this survey so KIS- Keep it simple)

o Has your question been approved? __________________ (signature of approving

teacher)

o The topic/topic question and the explanation of why you chose it is included in your

Informational Brochure

Did you develop a strategy for collecting your data?

o Use the Green Instruction sheet to guide you in the creation of your Informational

Brochure

o Your brochure needs to include something like a table/tally chart.

Did you outline a method to select a “sample or population” to complete your survey?

o On your Informational Brochure you need to present/illustrate/clarify how you chose

your sample population (group). Use mathematical terminology in your explanation.

(See the Green Instruction sheet for additional information)

o Your choices for outlining might include: a written paragraph, a bulleted list, SmartArt

insert/import, pictures/diagram with caption, ect.

Math 9 – Unit 9 Statistics and Probability

Did you create a visual display of your data that you can use to analyze?

o Enter your data into a spreadsheet in excel (see the Yellow Excel Instruction Sheet )

o Use a graphing tool in excel to create a visual display of your data (pie chart, bar graph,

ect)

o Have you included :

Graph title

Axis titles

Legend

o Include your visual display in your brochure.

Did you summarize and communicate your findings?

o Briefly in your brochure

o More extensively in your PowerPoint – Refer to Green Information Sheet

Did you create and include a rubric on your informational brochure?

o Use the information discussed in math class.

GREEN INSTRUCTION SHEET

When you are conducting a survey to answer a particular question, consider some influencing factors as you choose a sample population and analyze your data.

For example: Let’s say there is a discussion in the town wondering in Athabasca

should adopt a curfew (time restriction) of 9:00pm for individuals under the age of 17.

Depending on the group of people your survey you may get completely different data. For

instance there is a strong likelihood that people over the age of 40 may agree with the

curfew; however, if you survey only those between ages 13-20 you may get data showing

that they completely disagree.

Influential factors:

Bias – Does the question lead people to choose a specific answer?

Use of language – Is the question worded clearly so that people understand what is being

asked?

Ethics – Does the question relate to a person’s morals or values? (Do they have to judge if

something is wrong or right?)

Cost – Does the cost of the survey outweigh the benefits?

Time and timing – Is the timing of the survey appropriate? Does the timing influence the

results?

Privacy – Do people have the right to refuse to answer? Are the responses kept

confidential?

Did you

reduce the

bias in your

data?

Math 9 – Unit 9 Statistics and Probability

Cultural sensitivity – Might the question offend people from different cultural groups?

For your assignment, we want you to think about the group you survey (I know we are

slightly limited) and how that might affect your results. The more people you survey the

more accurate your data.

Population vs Sample

Samples are commonly used because they are more manageable:

Here are a few types of samples:

1. Convenience sample – choosing individuals from the population who are easy to access

2. Stratified random sample - dividing the whole population into distinct groups, and then choosing the

same fraction of members from each group

3. Systematic sample – choosing individuals at fixed intervals from an ordered list of the whole

population

4. Voluntary response sample – an invitation for the whole population to participate

Which one are you going to use?

All of the individuals in the group are being surveyed

For example: For the teen curfew question – you would survey the entire population of Athabasca

Any group of individuals selected from the population

For example: Surveying 100 people who live in Athabasca

6. You know have your chosen graph but you need to have a title, legend and labels on the

axes. To do this, click on the quick layouts lower arrow to bring up the graph layout you

will need (layout 9).

7. Add a title and axes labels to your graph. You can change the labels by double-clicking

on them

Math 9 – Unit 9 Statistics and Probability

TALLY SHEET/DATA COLLECTION SHEET

This sheet is to be done in Microsoft Word. Here are some helpful tips.

Insert a table – this can be done by clicking on the Insert tab, choosing table and choosing

the size of your table.

Math 9 – Unit 9 Statistics and Probability

Merging cells allows you to turn more than one cell in the table into one cell. To find the

merge cells option, click on the Table Tools Layout tab. Highlight the cells you want to

merge and then choose Merge Cells

The cells that were highlighted become one.

To align the text within the cells use alignment area on the table tools layout tab
