Hi guys, I'm in a bit of stress here because I don't know when to use line of best fit and when to join the actual dots. I know for chemistry you generally use line of best fit, but what about for bio? I thought you did but then I found in one of the Excel books (2010, Q21a) that for something that I thought would be a bell curve they just joined the dots. What's the deal: do you get marks for either, or is there a specific time to use one or the other?
Thanks!
Thanks!
