What rule is used to determine if a categorical variable is approximately normally distributed?
Homework Answers
The empirical rule is used to determine if a categorical variable is approximately normally distributed.
The empirical rule follows three-sigma rule i.e. 68-95-99.7 rule which provides a quick estimate of the spread of data in a normal distribution for the given the mean and standard deviation. According to empirical rule:
68% of the data will fall within one standard deviation of the mean.
95% of the data will fall within two standard deviations of the mean.
99.7% of the data will fall within three standard deviations of the mean.
