**When you are given a data set in a SAC, which app should you use put it into your calculator** - 2.
**Immediately after you have put your data into your calculator, which App do you need to run to refresh the values on the other pages?** - 3.
**Which App should I run in order to populate the pages relating to Transformations?** - 4.
**It is always good practice to check the values you have entered. On which page could I expect to check the values of the data in a table format**? - 5.
**I need to look at the scatter plot of the bivariate data to determine which quadrant it might fit into. Which page would I go to?** - 6.
**I want a full list of details relating to the Linear Regression equation, form and strength, correlation coefficient and coefficient of deterimation. Which page will offer me a summary of these details?** - 7.
**The only way to truly tell if a set of data is linear is to look at its residual plot. Which page would I find the residual plot for the least squares regression line?** - 8.
**I have just run the transformation App to find the best transformation for the data set. Which page would give the equation for the line for the best transformation?** - 9.
**While a transformation may be determined to be the 'best' transformation because of its coefficient of determination, thats not enough to prove it will be accurate. You still need to look at the residual plot to see that the data is linear AFTER it has been transformed. Where would I find the residual plot for an x squared transformation?** - 10.
**While a transformation may be determined to be the 'best' transformation because of its coefficient of determination, thats not enough to prove it will be accurate.
