Based on this graph showing a set of data, a line that is the line of best fit include the following: C. line c.
In Mathematics and Statistics, there are different characteristics that are used for determining the line of best fit on a scatter plot and these include the following:
- The line should be very close to the data points as much as possible.
- The number of data points that are above the line should be equal to the number of data points that are below the line.
By critically observing the scatter plots using the aforementioned characteristics, we can reasonably infer and logically deduce that scatter plot C or graph C with points (4, 4) and (6, 6) best models the linear relationship between the data because the end points are almost equally divided on both sides of the line.
