```					Data Management Unit Using E-STAT for Grade 9 Mathematics
in Nova Scotia – on the Nova Scotia Learning Resources and Technology website               -

This 70-page document was written by Nova Scotia Ministry of Education staff (in
collaboration with Statistics Canada) for the Data Management Unit in grade 9
Mathematics. The activities and lessons utilize the data and graphing resources available
through Statistics Canada's E-STAT web site at http://estat.statcan.ca.

Below are examples developed by David MacFarlane (Dr. J.H. Gillis
High School, Antigonish, Nova Scotia) showing how he uses E-STAT
for teaching the grade 9 data management unit.

“I have found E-STAT extremely useful in teaching statistics in the
classroom. The statistical information that is available allows me to find
materials that my students can easily relate to. By connecting a
classroom activity to a headline in the new media students can see the
importance of understanding and interpreting statistics”

David MacFarlane, Dr. J.H. Gillis High School, Antigonish, Nova Scotia

Find the line of best fit


   students draw
line of best fit

   Calculate slope
Relevant data can be pulled from E-STAT to address current
issues.
Example:
Why did the teachers in British Columbia go on strike in October 2005?
Why did they have the support of so many (unionized) government employees?
We can then look at current trends by focusing on year 2000 where salaries begin to
drop.
Salaries in British Columbia

Salaries in the rest of Canada
Displaying data – Which graph gives you a better understanding of how
many jobs are created by tourism?

When should we use a pie graph?
