What are the coefficients of correlation between miles per gallon and horsepower? Between miles per gallon and the weight of the car? What are the directions and strengths of these coefficients? Do the coefficients of correlation indicate a strong correlation, weak correlation, or no correlation between these variables? See Step 4 in the Python script.
# create correlation matrix for mpg, wt, and hp.
# The correlation coefficient between mpg and wt is contained in the cell for mpg row and wt column (or wt row and mpg column).
# The correlation coefficient between mpg and hp is contained in the cell for mpg row and hp column (or hp row and mpg column).
mpg_wt_corr = cars_df[['mpg','wt','hp']].corr()
print(mpg_wt_corr)
mpg wt hp
mpg 1.000000 -0.861343 -0.771313
wt -0.861343 1.000000 0.645234
hp -0.771313 0.645234 1.000000
