High variability graph
WebThe engineer creates variability charts to look for possible trends and interactions in the data. Open the sample data, SinteringTime.MTW. Choose Stat > Quality Tools > Variability Chart. In Responses, enter Strength. In Factors (1-8, outermost first), enter MetalType and SinterTime. Select Standard deviation chart. WebSo, what variability refers to is how dispersed or spread out the data values are, or looking at it from another point of view how wide the data distribution is when it is graphed. If all data values are the same, then, of course, there is zero variability. The graph of the distribution would have zero width.
