Figure 10.14 Bias Report
The bias (Response minus Standard) is calculated for every row. At the top is a histogram of the bias, along
with a t-test testing if the average bias is equal to 0. On the bottom right is a table of average bias values for
each part. To show confidence intervals for the bias, right-click in the table and select the options under the
Columns submenu. Each of these bias averages is plotted on the graph along with the actual bias values for
every part, so you can see the spread. In this example, Part number 1 is biased high and parts 4 and 5 are
biased low.
The Measurement Bias Report node has the following options on the popup menu:
Confidence Intervals calculates confidence intervals for the average bias for each part, and places marks
on the Measurement Bias Report by Standard plot.
Measurement Error Graphs
produces plot and summary statistics of bias by part.
