Line of best fit

No. When you draw a best line of fit on the scattered plot, the line would not be straight.

No, that would be quite unusual if if did, although not impossible.

A trend line is graphed from a linear, exponential, logarithmic or other equation, and trys to fit the sorted data that you have. But it may or may not be correlated. The line of best fit is the trend line that best fits your data, having a high correlation. R closer to 1.

Based on the information given in the question, nothing particularly is true. The line need not be straight, or even a smooth curve. There need not be any points on the line but there need not be any points not on it.

The trend line for a scatter plot is a line that best captures the nature of the relationship between two variables. It may or may not be straight.

A scatter diagram will give a quick but rough extimate of the trend line - especially if there is a lot of variation about the trend. The least squares method will be more accurate.

Scatter graphs are best. Line graphs are OK if the trend is linear but not much good if the trend is non-linear.
