How can I calculate significant t value (look at P87,88,89&90 3th edition of MSA manual)?
See the Stability tab in the file attached to my blog entry. Scroll to the bottom and you will find the bias study calculations.
v means the degrees of freedom in the sample. This is typically n - 1 where n is the sample size.Thank you Miner for your quick response! but as I asked in page 89(3th edition of MSA manual) are written :"t(v,1-@/2) is found using the standard t tables." can you explain it for me?
v means the degrees of freedom in the sample. This is typically n - 1 where n is the sample size.
@ means the alpha value. This is the amount of acceptable risk that you will make an incorrect conclusion that you have statistical significance when it is not. Alpha is normally set at 0.05.
Significant t Value (two-sided) and t(critical) mean the same thing.Ok, How can I calculate it? Or I saw your file, it is so useful but I have a question:
You calculate the t(bias) and t(critical) and explain for acceptable most t(bias) < t(critical) , but in MSA manual we have different chart(enclosed), what`s the relation between it and your formula?
Significant t Value (two-sided) and t(critical) mean the same thing.
The 95% confidence limits of the Bias are additional values that are not included in my Excel file. See Confidence interval.
Hello,
I'm haveing the same problem , I don't Know how to calc. the confidence interval and I can not find this T Table.
