Data Portrayal Team: The Authors Case One Example
Purpose • To exploit the data tracking tools • To apply the basic data analysis tools Case One Example
Data Analysis • Set average value = 1.47 • Set standard deviation = 0.19 • Upper system limit = 2.06 • Lower system limit = 0.31 Case One Example
Tracking Diagram Case One Example
Histogram of the Data Set Case One Example
Analysis • One data point exceeds the process control limit, which is to be expected only a few times in a thousand. • This point requires special attention • The rest of the data seem to be well behaved. Case One Example
