How do you find linear regression on a calculator?
Linear Regressions are used to extrapolate lines and find the "best fit".To find a linear regression, you must have a graphing calculator (Texas Instruments: TI-83/Plus, TI-84, etc.)Step 1. Hit the STAT button.Step 2. ClrList, to enter data, the lists must be clear.Step 3. Hit the buttons 2nd, 1, comma(located above the 7) , 2nd, 2.Step 4. Hit the STAT button again.Step 5. Edit Now enter data into the L1 and L2.Step 6. Now, hit the STAT button once more.Step 7. Press the Right Arrow key in the corner. This will lead you to CALC.Step 8. Now press the 4 on the keyboard (LinReg ax+b)Step 9. Hit the buttons 2nd, 1, comma(located above the 7) , 2nd, 2.Step 10. Press the enter button.Your linear regression will be displayed on the screen as an ax+b (or mx+b) equation.
What implies a stronger linear relationship a correlation of plus 4 or a correlation of -6 and why?
Something is wrong. Correlations cannot be less than -1 or greater than 1.
What kind of relationship exists between the variables if your r value is close to plus 1?
When r is close to +1 the variables have a positive correlation between them; as the x-values increase, the corresponding y-values increase. There is also a strong linear correlation or relationship between the variables, when the value of r is close to +1.
