Complete the following steps to specify the two columns of data that you want to analyze.
- In Response (Y), enter the first column of numeric data that you want to compare. The response is also called the Y variable.
- In Predictor (X), enter the second column of numeric data that you want to compare to the response. The predictor is also called the X variable.
- In Error variance ratio (Y/X), enter the ratio of the measurement error variances in the response (Y) and the predictor (X). One way to obtain estimates of the error variances is to perform separate gage R&R studies for X and Y.
In this worksheet, New (Y) is the response and contains blood pressure measurements from a random sample of people using a new blood pressure monitor. Current (X) is the predictor and contains the blood pressure measurements from the same sample using the current monitor.
