Up until now in this book, you have been dealing with the situation in which you have had only one group or two groups of events or objects in your research study and only one measurement (i.e., variable) "number" on each of these. This chapter asks you to change gears again and ...
Using Your TI-NSpire Calculator: Linear Correlation and Regression Dr. Laura Schultz Statistics I This handout describes how to use your calculator for various linear correlation and regression applications. For illustration purposes, we will work with a data set consisting of the Amazon prices of ...

You may use the linear regression calculator to visualize this relationship on a graph. Correlation coefficient formula There are many formulas to calculate the correlation coefficient (all yielding the same result). This calculator uses the following: where n is the total number of samples, xi (...

If you want to perform linear regression on your data, check the least squares regression line calculator to find the best fit of aa and bb parameters. "Correlation does not equal causation" Always remember that even a very strong correlation between two variables does not mean there's a caus...
Now you can simply read off the correlation coefficient right from the screen (its r). Remember, if r doesn’t show on your calculator, then diagnostics need to be turned on. This is also the same place on the calculator where you will find the linear regression equation and the ...
