The authors of the paper \"Statistical Methods for Assessing Agreement Between Two Methods of Clinical Measurement" (International Journal of Nursing Studies [2010]: 931-936) compared two different instruments for measuring a person's ability to breathe out air. (This measurement is helpful in diagnosing various lung disorders.) The two instruments considered were a Wright peak ow meter and a mini-Wright peak ow meter. Seventeen people participated in the study, and for each person air ow was measured once using the Wright meter and once using the mini-Wright meter.

If the two types of meters produce different readings but there is a strong relationship between the readings, it would be possible to use a reading from the mini-Wright meter to predict the reading that the larger Wright meter would have given
