Then you can see above that the power for your data is only 38% which means if there is a difference you only have a 38% chance of seeing it. With a sample size of only 10, there will be a significant overlap of the two confidence intervals so it will not be easy to see a difference. I would not make a decision that the two groups are s…[Read more]
P-value for normality for Sample 1 is .485 and for Sample 2 is .020. Close enough with respect to the normality assumption. In that case, maybe the 2 sample t can be used. The p values for the equal variances are just a bit above .05 so maybe close enough. Bottom line is that maybe the 2 sample will work in this case. Since no difference was…[Read more]
@fausto.galetto Since you were not able to reject the null hypothesis and see a difference, I would want to know the Power of your tests. Given the small sample sizes is there no difference as you state or is the lack of noticeable difference due to a low power?

@csetter Links to your own companies/products/services are considered self-promotion and are not allowed on the forum. The posts had been flagged by our system due to their multiple links. A glitch in our hardware briefly allowed them to go live. As soon as I became aware of that, I removed them. (You’d already gotten a message without the links…[Read more]

@csetter Not buggy, per se. Your responses went into a queue for review since they contained multiple links (a favorite tool of spammers that we do our best to head off at the pass). Adding a notification for users is in our tech team’s queue at this very moment. Apologies for the inconvenience!

@HV1234 I am not sure I understand this completely but let me see if I can help. It has been a very long time since I have used GD&T. When you say that >/= 1.0 is good and 0.5-1.0 is also then in terms of a Cpk they are both within specification. That is about the extent of what you get from Cpk. It really doesn’t explain degrees of goodness. It…[Read more]
@amrlord I am not sure what the point was to the long diatribe but since nobody else wants to answer you I will take a shot at it. Participation in Continuous improvement is not gender, religion, nationality, race, etc. sensitive. The younger generation issue doesn’t change first principles, mechanical engineering, etc. There are courses out there…[Read more]
@AlonzoMosley You asked for peoples input. I gave you my input. I have no obligation to agree with you as you don’t have any obligation to agree with me. Do whatever you want.
It always sounds good “I am working on employee communication.” If you ask and don’t do anything with the input you just did a huge amount of damage to any future…[Read more]
@fausto.galetto As I previously explained, self-promotion (which includes listing your published articles/linking to your content) is not permitted in the forum. You’re welcome to include as much of this information as you’d like in your User Profile.
@AlonzoMosley Wecome to the trap “just ask the people on the line.” As you have already found out 1. just because it comes from someone on the line doesn’t mean it is a good idea 2. if you cannot handle the load don’t ask because asking and not doing anything makes it look like you don’t care and that is actually worse than just plain not…[Read more]
