Least squares, more like 'least favorite' amirite? But seriously, D is the correct answer. Regression lines don't fit themselves, you know!

Yeah, least squares method is definitely not a favorite. But it does help in calculating a best fit regression line.

I remember learning that the least squares method is a common technique in statistics for estimating the unknown parameters in a linear regression model.

The least squares method? Isn't that what my grandma uses to measure her fabric for quilting? I'm going with B, just to be different.

I agree with Vanna, it helps in finding the line that minimizes the sum of the squares of the differences between the observed and predicted values.
