2. How to conduct a survey http://safeYouTube.net/w/tcVc

3. How to represent the data

4. Step 1: Statistical Question
Write a non-biased survey question
Example: how many hours do 6th graders at country springs spend online?
Must have a numerical response
Variety of responses
Get it approved by teacher

5. Step 2: who will you survey?
Define Population
Example – my population is the 89 6th graders that attend country springs elementary school.
Sample – how many will you survey?
Example- I surveyed ten 6th graders from of each of the three classes; 30 6th graders in all.
Type of survey
Example - I used a Simple Random sample (SRS) to collect data. I used numbered sticks to randomly select 10 6th graders from each of the 6th grade classes.
Simple Random sample (SRS) (everyone has equal chance) , systematic (every nth) , stratified (random within group)
Questionnaire, interview, convenience
Collect data – keep this data in chart

6. Create this page – page 1 (this goes after table of contents)
TITLE: Research goals
Statistical Survey Question
Population:
Sample:
Describe how you will survey…
Purpose: what to want to learn from your data? How will you use it?
Add clip art to match your survey topic

7. Create this page – #2
Survey Question
Table of data

8. Step 3: calculate measures of center
Find measures of center:   mean, median and mode
Create a line plot to display data
Find Measures of variance: range, median, q1, q2, iqr and outliers
Create line plots
Find mean absolute deviation (mad)

10. Create this – page 3 Survey question
Mean, median, mode – create a box to include your data (use shapes)
Interpret outliers – how do they affect measures of center?
Create line plot – be sure to label

11. Measure of center

12. Create this page – Page 4
Measures of Variance
Measures of Standard Deviation MAD

15. Step 3: display data -graphs1
Create tally/frequency chart 2
Dot plot (interval 1) 3
Histogram (equal intervals that include all of your data) 4
Stem-and-leaf plot  5
Box-and-whisker-plot 6
*use excel, word, or create a graph   

16. *You may put 1 or 2 graphs per page
Stem-And-Leaf
Create these pages
*Pages 5-8
*You may put 1 or 2 graphs per page
Histogram

17. Graphing data

18. Graphs continued

19. Step 4: Analyze results – create this page – Final page-
write a paragraph summarizing your conclusions based on your data collection.
Was your survey effective?  did people know what you were asking?  
8-10 sentences - typed
Include measures of center – mean, median, mode, range
What do they tell you about the data?
Did you have outliers?  How did they affect your measures?
What observations can make from your graphs and charts?
Use statistical language/vocabulary in your responses!

20. Step 5: create poster/notebook
Create a folder to hold all of your data, charts, graphs and written conclusion
Create a poster for the cover that details:
Survey question
Population
Sample
Survey method
Results/conclusions
Graphs/tables
