Hey everyone, welcome to this lecture how to perform a rank chart on Minitab. Download this data from the resources section of this lecture and copy and paste the filled volume column in Minitab. Choose stat, quality tools, rank chart, I repeat to stat, quality tools, rank chart. In single column, enter fill volume in subgroup size, enter one and click OK. This is the rank chart you have to observe the p value for clustering, mixtures, trends and oscillation. If the p value for any one or more variables is less than 0.05 the data is unstable and has special causes.

However, if the p value for all the variables is greater than 0.05 the data is stable and only has Common causes. in this situation the p value for clustering, mixtures, trends and oscillations is greater than 0.05. Hence, the given data of fill volume in a random sample of 10 containers is stable. It is now time to do an activity. Thank you for attending this lecture. See you in the next one.
