Curriculum Links “Students will collect data that can be modelled as a [linear/quadratic/exponential/ sinusoidal] function… from secondary sources (e.g., websites such as Statistics Canada, E-STAT)” sinusoidal] function… from secondary sources (e.g., websites such as Statistics Canada, E-STAT)” Ontario Mathematics Curriculum
Step 1: Access the website
Step 2: Select a Dataset 1 2
Two Options for Step 2 Option 1: Table Number This allows you to specify the attributes you want to examine This allows you to specify the attributes you want to examine Option 2: Vector Number Attributes are pre-selected for you Attributes are pre-selected for you
Step 3: Output Data Once you have retrieved your data, you have several options within E-STAT for output: Screen Output formats: HTML, Plain text, etc. Screen Output formats: HTML, Plain text, etc. Downloadable File formats: CSV, PRN, etc. Downloadable File formats: CSV, PRN, etc. Graph formats: Line graph, Scatter graph, etc. Graph formats: Line graph, Scatter graph, etc.

Excel Example Federal Debt
Births during the Baby boom can be modelled by a quadratic function
Baby boom births can be modelled better by quadratic + sine function
Travelers to Canada can be modelled by linear + sine function
Canada’s rural population increased linearly from 1871 to 1971
Urban population increased exponentially
Total population modelled by linear + exponential function
