Answer 2

The term yardstick refers to what is a normal response.  It really has nothing to do with a yardstick and can be used in many situations.  A yardstick is a measurement that has been tested over and over and than that measurement becomes the standard.
Say the yardstick for a reaction time is 5 seconds
Meaning that is what a normal healthy person can do it in.
Joan has the reaction in 4.8 second.  Well she is on the the bell curve and did better than the yardstick test measure.
