Pearson correlation scatter plot
WebUse scatterplots to show relationships between pairs of continuous variables. These graphs display symbols at the X, Y coordinates of the data points for the paired variables. Scatterplots are also known as scattergrams and scatter charts. The pattern of dots on a scatterplot allows you to determine whether a relationship or correlation exists ... Web23 hours ago · But the line of best fit is being strongly influenced a few denser regions in the scatter plot. So I decided to use matplotlib.pyplot.hist2d for 2d binning. Now I am curious to see if there is an improvement in identifying the correlation i.e. line of best fit best represents the actual correlation without the effect of bin count.
