If your process has a target value, enter the number. Minitab displays the target value on the capability histogram and the process data table.

Enter the width of the tolerance in number of standard deviations (σ). By default, the tolerance is 6 standard deviations wide (3 standard deviations on each side of the process mean).

Minitab interprets the K value as the width of a two-sided tolerance. If you want to use a one-sided tolerance, enter a two-sided tolerance value that is twice that of the one-sided tolerance. For example, if you want to use a one-sided tolerance of 3σ, enter 6.

If you want the tolerance value that you enter to be the default setting for every capability analysis that you perform, choose and enter the default tolerance.

Select how you want to display the observed out-of-specification values:

- Parts per million: Display the values in parts per million (PPM).
- Percents: Display the values as percentages.

- Include confidence intervals
- Select to display confidence intervals for the capability indices. If the
analysis selects a method that uses a nonnormal distribution, then the
results do not include confidence intervals.
- Confidence level
- Enter a confidence level between 0 and 100. Usually, a confidence level of 95% works well. A 95% confidence level indicates that if you took 100 random samples of the same size from the process, you could expect approximately 95 of the samples to produce confidence intervals that contain the actual value of the capability index for the process (if all the process data could be collected and analyzed).
- Confidence intervals
- Select the type of confidence interval or bound that you want to
display. If the analysis selects a method that uses a nonnormal
distribution, then the results do not include confidence
intervals.
- One-sided:
Displays lower confidence bounds for capability indices
for the method that uses the normal distribution.
Displays upper confidence bounds for PPM or %
out-of-specification limits. Use one-sided confidence
bounds for the following:
- To be more confident that a capability index is greater than a required value. For example, to be more confident that Cp is greater than 1.33.
- To be more confident that a PPM or % out-of-specification limits is less than a required value. For example, to be more confident that PPM Total out-of-specification is less than 100.

- Two-sided: Display a confidence interval that has both a lower and an upper confidence bound.

- One-sided:
Displays lower confidence bounds for capability indices
for the method that uses the normal distribution.
Displays upper confidence bounds for PPM or %
out-of-specification limits. Use one-sided confidence
bounds for the following:

If you want to change which statistics display by default, choose and change the default display setting.
