Best-Fit Line
Given a series of data, it could be interesting to try to model them with a linear equation.
We are provided with a dataset and when plotting them we get the graph below:
Since the behavior of the data looks somewhat aligned, a line would fit very well to this dataset.
There are several automated tools that help us to find the slope and the intercept of such a line. We'll use MS Excel.
The regression line is found to be:
y = 0.3x + 7
The best-line along with the original data is shown below:
