![]() It also shows the t Stat, P-value, F and Significance F, whatever they may be. But some sources refer to r-squared which seems to be the SD, so a value close to zero is good. Having used Excel's regression tool, for example, how do I interpret the results? Presumably if R is close to 1 this is good (although if there are many data items it seems as though it can be small yet still be significant). But how do I include day of week, since just coding it as Sunday=1, Monday=2 etc feels very wrong? Presumably multiple regression analysis / ANOVA is the tool to use. I imagine there's a strong correlation between time and distance and probably a weaker one to engine size (and none to shoe size). Imagine that I have a set of car-related data such as It's a long time since I studied any stats and the jargon seems to have changed. ![]() I need a little help to move in the right direction.
