Quizplus · Accepted Answer

The chi-square distribution is positively skewed. It is a continuous probability distribution that is used in hypothesis testing and statistical analyses, particularly for comparing observed and expected data. Its skewness arises because the chi-square variable is the sum of squared standard normal variables, and the square of a normal variable is always positive. This results in a distribution that is skewed to the right, with a longer tail on the positive side of the distribution.
