We spent the first part of class finishing up the review problems and answering any questions about the test material. Be sure that you correct and review all of these problems for your test Wednesday.
After the review problems we introduced Mathematical Modeling, the process of analyzing and interpreting data. We learned the process for graphing statistical data, as well as finding the Linear Regression line for any set of points. Remember, when looking at a linear regression line you use the correlation coefficient to determine how exact your line fits the given data. The closer to 1, the better the fit. If you need a review of how to graph this data on the calculator click the link to the right.
For this weekend you need to do some research on the exponential growth of the Starbucks franchise. You should use the link on the right and navigate through until you find the Company Timeline. Read over the timeline as it gives interesting information. As you go through the information create a table of growth since the first franchise. Your first year will be 1971 when the first Starbucks opened in Seattle. Start this year as 0, and continue up from there. Notice that there will not be a number for every year, so only include what is given in this timeline. We will use this data next week!
Have a nice LONG weekend!
- Homework: Create a table of values for the year and # of Starbucks stores at the end of that given year.
- Test will be Wednesday October 10th!
