I have to produce a simple handout for intermediate Excel Chart/Graphs
users, which unfortunately for me has to include Scatter Graphs. I can
follow the logic behind the trendine but am not sure how to interpret
the trendline equation. For instance on the chart I have produced the
trendline equation is y = 1.4909x + 3.7636. Is this good or bad, and
at what point does it become of no use? I am looking for a simple
explanation/definition for non mathmaticians, and in less than 30
words!!
Thanks
