I the Chi-Square Distribution Is Positively Skewed

i. The chi-square distribution is positively skewed. ii. Nonparametric tests of hypothesis, which are also called distribution free tests, require the population to be normally distributed.
iii. The computed value of chi-square is always positive because the difference between the observed frequencies and the expected frequencies are squared.
