How do you do DELTA Change? Serial Numbers? and Trends??

[John915]

I have research data in excel spreadsheets and need help on how to do Delta Change and Trends...Then Have to make charts with those results. Please help. Thanks in advance!

Your question is very general and very vague. It would help if you would describe something about the data that you have and what kind of charts and analysis you need.

"Delta" and "Change" mean the same thing so I don't know what you mean by "Delta Change". Delta is the math term for the difference between two values of a variable taken at different points, sometimes read as "change".

Excel can also do trend analysis but trend analysis can get quite complicated, depending on what you need to do.

It can be difficult to respond to such an open ended request. What specifically do you need help with? Can you explain your terms? What does "DELTA change" mean? What is the "logic" behind generating your serial numbers? What kind of trend are you trying to analyze? How do you want to perform the analysis (we can usually do well at helping you program a known algorithm into the spreadsheet, but we are not always knowledgeable about choosing an algorithm for an unspecified analysis)?
