Start with plotting the data on the coordinate plane.
- 0.5
We have been given a table of values.
Next, we will draw a line among the points. When drawing a trend line, we want the line to be as close to as many points as possible.
Since the points loosely follow the line with a negative slope, r is between - 1 and 0. Since the correlation is weak, r is closer to - 0.5.
