Folks I need your feedback regarding the use of computer for statistical calculations or improving the inspection efficiency.

Folks I need your feedback regarding the use of computer for statistical calculations or improving the inspection efficiency.Your needs vary according to your capabilities, which you don't describe. I will therefore list a range of available help as I know it.

There is a good book out called "Data Analysis Using (Microsoft) Excel" by Michael Middleton. This is the cheapest tool I know of, with which you can design your own analytical models.

I have also used the commercially available tool Analyze-It For Microsoft Excel, which is a macros that quickly makes smart looking little charts with small data sets.

As for "use of computer for improving the inspection efficiency" I am not sure I understand you. Can you please elaborate?

Wouldn't be any way to get out 2,200 charts and files per month without heavy automation of data processing.

I voted "yes" and I feel I need to elaborate
It is important that folks understand what is involved in the calculations being performed by the computer, but under no circumstances should folks have to go through the grunt work and possibility of human error when doing the calculations when the tool (computer) makes it easier.

Craftsmen might use hand tools in making exquisite, one-of-a-kind products, but a production house will certainly use power tools for efficiency.

I Agree with Wes. Computers do provide enormous power to perform complex, tedious, and repetitive calculations.

The other side of it IMO is that people can sometimes get into a "Have numbers, will crunch" mode and focus entirely on the final output (such as a Cpk number or a GRR%) and forget to look at the underlying data for signals.
