In statistics, Spearman's rank correlation coefficient or Spearman's rho, named after Charles Spearman and often denoted by the Greek letter Ï {\displaystyle \rho } (rho) or as r s {\displaystyle r_{s}} , is a nonparametric measure of rank correlation (statistical dependence between the ranking of two variables).
Freedom of Speech and Freedom to Criticize should have limit. Sometimes people and in particular, the big fishes, (politicians) go beyond the limit and make everyone complain for they even go to the extent of even abusing their seniors e.g.; presidents.
The First Amendment's freedom of speech right not only proscribes most government restrictions on the content of speech and ability to speak, but also protects the right to receive information, prohibits most government restrictions or burdens that discriminate between speakers, restricts the tort liability of individuals for certain speech, and prevents the government from requiring individuals and corporations to speak or finance certain types of speech with which they don't agree.
