Cumulative Probability 1

[Shahram56]

I would be grateful if somebody reply back what is cumulative probability and how can I draw a graph for cumulative probability for around 20 datas?

Advice are appreciated.

It seems he has his own procedure that I have mentioned and I have added his graph also for reference. I would like too know your comments also.

thank you in advance.

Try explaining what he is doing. I don't understand your original explanation, and therefore, the graph doesn't mean anything to me.

My procedure is what you told me but his procedure is that he devides the space in y-axis from 0 to 100 with the same distance. So all the data in the y direction have the same distance from each other. if you take a look at post.doc and post1 ( post1.doc is his graph and post.doc is my graph with your procedure).

What is he trying to accomplish by doing that? What version of Excel are you using? Send me your raw data, and graphs (your version and his version). You should be able to get my email from when I signed up on your discussion.

After looking at his plot, maybe he wants to see the survival plot. Try making that and showing it to him. Also, add more data points to smooth out your graph.

Did you re-run the data using a Weibull distibution?

What voltage do you take your leakage current reading?

I diid not rerun the data using the weibul actually, i will read uit and will do it again.
I have tkaen the leakage current at 2V.
