Agenda
Estimating trend lines
Judo Math into
Test Analysis-excel sheet
I can estimate the line of
best fit for a given scatter
plot and write an equation
to represent it.

4. Is there a relationship? (trend, correlation, association)
Ex1

5. Can we estimate a line that would be close to most points?

6. Write the equation of the trend line

7. Write an equation for the line of best fit
Ex 2
Write an equation for the line of best fit

8. Would all of our lines be exactly the same?
NO-trend lines are estimates-we may draw lines that look similar. Therefore there are a range of acceptable values for y-int and slopes

9. Practice
Drawing trend lines
& writing equations

I can use the line of best fit to make predictions (interpolate/extrapolate).

40. Interpolation vs. Extrapolation
Interpolation is a prediction within our range of data.
Ex. We have average temperature values for Lenoir City from , what was the temperature in 1999.
Extrapolation is prediction outside the range of our data.
Ex. We have average temperature values for Lenoir City from , what was the temperature in 1990.

43. This was outside of our range of data
You extrapolated yesterday and didn’t even know it!
