Hey everyone, welcome to this activity to create a run chart, you are given the data of 10 observations on the effective life in minutes of a catalyst using a chemical reaction. You want to analyze this data. But before proceeding with the analysis, you want to first identify if the data is stable. Perform a rank chart and identify the data stability. subgroup size is equal to one. I have uploaded this data in a spreadsheet in the resources section of this lecture, post creation of the rank chart, please upload a screenshot of the graph on the q&a discussion board.

I would love to review your progress. Also add your inferences. Thank you for attending. See you in the activity solutions lecture.
