Today in class, everyone received instructions for their Statistics “poster” Project. This will be due (probably) at the end of class on Wednesday, Feb 3.
Below is a TON of data you might choose to analyze for your project. Tons of Data
If you lost your assignment sheet, then you can also find it on page 140 of the attached file.
Today in class we worked on the Closure Problems for Chapter 6. Make sure that they are complete (skipping 125) for class tomorrow.
Tomorrow in class we will begin our Statistics Project. Please plan on it being due at the end of class next Wednesday.
Today in class we learned how to use quadratic and exponential regression to find different best fit lines. That is because not all data is linear.
We can determine which function to use, or how good each one is with our residual plot, r, and r squared values.
Remember: r is not the SLOPE of the line of best fit. It measures the strength of the correlation!
Today in class we learned what r (the correlation coefficient) tells us about our line of best fit.
It is EASIEST to find r when using Desmos. (That’s my tip for everyone this weekend.)
Now go and complete the Review & Preview for 6.2.2.
Today in class we practiced using Desmos and our TI-Nspire to make Least Squares Lines of Best Fit.
Tonight, complete the Review & Preview for lesson 6.1.4. Skip problem 40.
Today in class we were able to tie together (with a pretty bow) everything we have learned about scatter plots, lines of best fit, and residuals. We used this to find the bound (range) of reasonable answers.
Tonight, please complete the Review & Preview for 6.1.3
Today in class we talked about how statisticians prefer to write equations y = a + bx.
We also discussed how to measure residuals on a scatter plot, and what the residuals can tell us about our line of best fit.
Tonight, please complete the Review & Preview for section 6.1.2
Today in class we reviewed some important vocabulary regarding scatter plots and modeling data. We also began a cool project that will take more than one day.
In the meantime, complete the Review and Preview for section 6-1 tonight for homework. Skip 6 – 4, since we haven’t finished the Football Project yet.
6 – 7 might be hard. Use the homework help if you get stuck. If you get really stuck, please let me know so that we can study these skills more in depth later in the year.
Attached is a 10 page document reviewing the key concepts and skills related to arithmetic and geometric sequences. There are also some great practice problems!
Tonight, please create equations for 8.5 Challenge Problems 1 – 5.
Then study for your Constitution Test!!!
