My job requires me to update excel reports and also send out analysis and summaries. My concern is, I don't really have a lot of experience with statistics, numbers analysis, or have enough background to know what type of tools are available for me. For example, lets say I send out a weekly report that tells how a company is doing in terms of sales. There is the total $$ generated, total items sold, and it can be filtered down to the state level. My ideas of an analysis includes: comparing how this week is compared to last week, this month vs last month, average price, this year vs last year etc etc...and maybe drilling down by state to identify who is doing best or worst. Are there any other methods of analysis that I can use, just so I have more options in my review? I know i"m being vague, and it is because I'm a complete newbie and looking for general advice and ideas.
