Determine if the statements below are true or false. For each false statement, suggest an alternative wording to make it a true statement. The chi-square distribution, just like the normal distribution, has two parameters, mean and standard deviation. False, there is only one parameter, degrees of freedom. The chi-square distribution is always right skewed, regardless of the value of the degrees of freedom parameter. True. The chi-square statistic is always positive. True because each difference is squared. As the degrees of freedom increases, the shape of the chi-square distribution becomes more skewed. False, it becomes less skewed and more normal as the degrees of freedom increases.
