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.
Prior restraint is the censorship of speech by the government before the speech is published, distributed, or otherwise heard or read. The right to free speech (also known as 'free expression') is protected by the First Amendment to the United States Constitution, which prohibits the government from making any law 'abridging the freedom of speech.'
