Quizplus · Accepted Answer

Smoothing techniques are used to remove noise from a scatterplot, which helps in identifying trends and patterns in the data. It does not change the regression equation or the intercept, nor does it increase the absolute value of the correlation coefficient or the probability of the r value being significant.
