I have some measurements from the production data's and analyse it on minitab and on an excel spreadsheet which calculates the Cpk.
As seen on the attachments, Cpk is calculated as 0,99 in excel with formulas but on minitab it is calculated as 1,16 but Ppk is 0,99 - as same as excel sheet-
My collagues in the company uses minitab for their porojects and they choose minitab and calculate Cpk as 1,16. But I put the excel sheet to production and mine is 0,99.
As I am new in statistical controls
, can someone help me ?
Thanks in advance.
