Hi everybody,

I want to create the same report than minitab for linearity and bias study. As showed in picture attached.You could also find my excel file.

As you can see, I am blocked with calculation of P-value for biais and linearity.

Thank you for your help.

Thank you Reynald, but unfortunately there is no P-value calculate in MSA 4rd edition or I didn't see it.
Is somebody know how to calculate these p-value for Biais and linearity ?

Thanks in advance.

The linearity part is just using the regression analysis found in the Data Analysis Add-in

The bias part is just a one-sample t-test against the hypothesis that bias = 0.

Can you do this Excel?

Thank you so much Reynald and Statistical Seven.

I succed for linearity, but I am steel struggling with calculation of 4td column in the example you post Reynald. You could find attached the excel file where I re-do the example.

How can I calculate the 4td column (column I in my excel)

After I will get this value, I will calculate the p value with:
= Tdist( t , Count(count sample of each reference) -1)
Am I right ?

Thank you for your help again.

Woow thank you guys !

It is progressing a lot ! I compared Minitab and Excel sheet I have slight difference on P-value. Do you know why ?

Thanks again.
