}#throws a warning about "standard deviation is 0", because sometimes by chance everyone in random sample has the same Nearest10 score

#*******RESULT******#
#Correlation between k-nearest score calculated for random sample of 60 individuals from each neighborhood, versus the same metric calculated for the entire neighborhood. The reported means and standard deviations of the correlations are for 500 random samples of 60 individuals from each neighborhood.
