Enter your data for Acceptance I-MR Chart

Choose Stat > Control Charts > Acceptance Charts > I-MR.

Complete the following steps to enter the measurement data, specification limits, and acceptance criteria.

For an Acceptance I-MR chart, all the measurements for a variable must be in one column.

In Variables, enter one or more columns of measurement data. If you enter more than one column, Minitab creates a separate Acceptance I-MR chart for each column.
In Lower spec or Upper spec, enter at least one specification limit. If you enter both limits, the lower specification limit must be less than the upper specification limit.
In Accepted percentage outside of each spec limit, enter the maximum percentage of process output that can be outside each specification limit. For example, enter 1 to allow 1% of process output to fall outside a specification limit.
In Probability of intervention if exceeded, enter the probability that a point is outside a control limit when the percentage of process output outside of specification exceeds the accepted percentage. The default is 0.99.

In this worksheet, Weight contains the weight of individual observations.
