What's Negative Correlation?

What is a negative correlation?

Summary

  1. A set of ordered pairs will have a negative correlation if the y-values decrease as x-values increase
  2. Let's graph some points and see what the line of fit is like
  3. A 'line of fit' is a line that gives a rough idea of what direction points seem to be going in a scatter plot
  4. The y-values decrease as the x-values increase in this line of fit, so the line of fit has a negative slope
  5. A negative slope means it has a negative correlation

Notes

    1. A data set is usually a set of ordered pairs
    1. A 'line of fit' is a line that gives a rough idea of what direction points seem to be going in a scatter plot
    1. The 'data' is graphed as a scatter plot of ordered pairs
    1. The 'line of fit' has a negative slope because as x-values increase, y-values decrease
    2. Remember, a negative slope means the data has a negative correlation
