this is stephanie from statisticshowto.com,and in this video i will be showing you how to find a linear regression equation on theti-83. the first thing we need to do is enter ourdata into a list. press stat.press enter. if you already have data in here, you wouldwant to clear the data.
How To Add Fractions On Ti-83, you can move the cursor on to l1, press theclear button and then press enter. i do not have any data so i am going to entermy x variable into the first column, l1. for the set of data over here, i am goingto enter 1. press enter.two, three, four, and five.
i am going to move over to the next column,l2. enter my y variables.once you have entered your variables, press the stat button.use the scroll key to highlight calc which is 4 for linear regression.scroll down and press enter. press enter again and we have our data thatwe need for our equation. for linear regression, y equals ax plus bour a is 25.3. our b is -34.9.so our linear regression equation would be 25.3x minus 34.9.that is how to use the ti-83 to find a linear regression equation.visit us at statisticshowto.com for more articles
and videos on everything elementary statistics.
