Good reference sites or material to help me brush up quickly on Gage R&R

Good Morning Everyone;
I find myself in a bit of a pickle.
I have been away from the statistic aspect of QC for almost 20 years. I was tossed into a Gage R&R problem this week, as i am the only one at my company with a history.
Does anyone have any good refrence sites or material to help me brush up quickly? I am actually on my last two weeks here at PSI, but i want to leave on a good note.

Thanks in advance for any help figuring out why this R&R is over 80%

Hi Mark,

Learning fast is good.
Getting the results from those who have already learned "can" be even better.

Do you want to post your data?

Seems like re-learning only has value for you for two weeks.....willing to take a shortcut to results?

As to your question...the best reference would likely be MSA itself.

Welcome to the Cove.
It would be good if you could post your data. Also, have a look at Miner's MSA Blog where there's a lot of good information from a very reliable source.

Re: Gage R&R

thanks folks for getting back so fast. First off - i have read through the MSA book, along with all my old stat/QC stat books. In my opinion there is not enough variance in the numbers, thus all error is moved to tools/inspectors. but to respond - please see the numbers below:
Appr#1: set one: 3.4108 3.4102 3.4106 3.4100 3.4101 3.4100 3.4105 3.4104 3.4103 3.4108 set two: 3.4106 3.4102 3.4107 3.4100 3.4103 3.4100 3.4105 3.4103 3.4106 3.4111 set 3 3.4105 3.4100 3.4109 3.4100 3.4104 3.4100 3.4105 3.4101 3.4105 3.41111
Appr#2 set one: 3.4111 3.4100 3.4105 3.4101 3.4106 3.4100 3.4106 3.4101 3.4106 3.4108 set two: 3.4104 3.4100 3.4102 3.41 3.4102 3.4100 3.4105 3.4104 3.4106 3.4109 set three: 3.4104 3.41 3.4101 3.4100 3.4107 3.4100 3.4107 3.41 3.4109 3.4108
Appr#3 set one: 3.411 3.4107 3.4103 3.41 3.4103 3.41 3.4108 3.4101 3.4108 3.4112
set two: 3.4154 3.4106 3.4101 3.4101 3.41 3.41 3.4102 3.4104 3.4106 3.4109

set three: .58 .582 .583 .581 .582 .581 .58 .58 .582 .582

these are two of the threee failures they are asking me to investigate.
while i was typing they gave me a new one. This one i am in charge from DOE to finish. So i hope i wopnt be as clueless with the latest.
Thanks again, if you can help me drop the %EV and %AV down to a manageable level. Were talking plastic here, very unstable and unpredicable.
Thanks again for all your help and expertise.

Re: Gage R&R

If you have the data in a spreadsheet it would be good if you would attach it to your post.

sample data attached. Excell 2007

hope this helps...

The nominal dimension and tolerance are also needed.

ok... .578 +/- .010 and 3.413 +/- .010
