Is there a relationship between two sets of data how do you know no because the data points are closed to the trendline yes because the data points are close to the trendline yes because the data points are not because of data points are not close to us

The relationship between two sets of data can be determined by analyzing how close the data points are to the trendline. If the data points are close to the trendline and show a clear pattern or correlation, then it is likely that there is a relationship between the two sets of data. Conversely, if the data points are scattered and do not follow a trendline, then there may not be a clear relationship between the two sets of data.
