Data analysis is one of the important aspect in a daily engineer's life. Whether we like it or not, most probably we are been tasked to analyze certain data and elucidate the meaning behind the summary of the data at hand. In the life a CVD engineer some of the data that we have to analyze is look at the how does the performance of certain process are compared to an existing process that we already have. Here statistical analysis plays a critical role towards establishing a conclusion whether the new process that we are qualifying is having better performance or lesser compared to our current baseline process.
The most common statistical software that I have used is JMP. It offers varies analytical and statistical tool which assist me in establishing correlation or making a statistical comparison whether between two processes. The software helps us to extract information and hence assist in providing a stronger argument in bringing to our final decision.
Therefore I strongly believe that an engineer should be well verse in the statistical tool so that we are able to make decision better by looking at statistic rather than relying on our gut feeling.
