 Hi, this is Don again with a second micro lesson on finding the regression equation or the equation, the regression line quickly. This time we're going to do it using StatCrunch. I'm going to click on this data again. I want to open this time in StatCrunch and now we have our data and we just need to go to Stat, Regression, Simple Linear. And we need to select our X variable and that's really something I see folks making a mistake with all the time. Be very careful identifying which is your predictor variable or your X variable and which is your response variable or your Y variable. In this case, it's pretty straightforward. They give us length as our X variable and girth as our Y variable and we just want a fitted line plot and I think that's all we're going to need for this. We'll click on compute and we get our results here. Drag that down so you can see them. We get our intercept, which is B, remember the equation, Y equal MX plus B is 5.87 and our slope or M is equal to 0.723 or 0.72. I almost forgot that we did ask StatCrunch to give us the scatter plot and I just need to click on the little arrow there and you can see here we've got our fitted line. It doesn't show the equation, but you have that from the first part of the results. You might notice that they have truncated both the X-axis, the length-axis, and the Y-girth-axis. You should be aware of that, but that's really all there is to this equation.
