Q: Where can I find weather data?

A: There are many possible sources. A source like Environment Canada is very reliable but you will have to sort through it to find the information you want.

You might want to pick a location for which there is lots of data rather than researching data for a town that may not have records available.

https://climate.weather.gc.ca/index_e.htmlAs we said in class, you may need to use a smaller set of data rather than using every point available, especially if you are using the TI84 or plotting by hand. (i.e. you almost certainly will need to simplify the data!) Excel or Google Sheets will manage a lot more data in terms of sorting, doing calculations, plotting, etc. but that is not a requirement. Interpreting and organizing data is part of this assignment and demonstrating that you can do this in an actual real-life situation shows a high degree of skill and understanding.

Q: Finding a sinusoidal model.

A: You can use any of the methods mentioned in the assignment. In all cases it helps to look at a scatter plot/STATPLOT to see what you're doing. There are similar questions in 5.3, 5.5 in the textbook. (It's either the "Bay of Fundy" type of question or doing a regression.)

And remember, using technology and looking really professional is excellent but you can do a good assignment by keeping things simple.
