- Look at the attached table and record the ages in the Y column.
- How well were you able to estimate the ages of these famous people?
To help answer this question, make a scatterplot with your estimate
of the age on the horizontal axis and the actual age on the vertical
axis.
- Where will a point lie if you estimate it correctly? Draw in the
line that represents estimates that are 100% accurate. What is the
equation of this line?
- What does it mean if a point is above the line?
_________________________________________________________________________
In general, did you overestimate or underestimate?
_________________________________________________________________________
How can you tell this from your scatter plot?

As a result of this activity,
students will be able to model the equation y = x.
