Question

Base on this data DESCRIBE the result of Product Quality, in paragraph form.

Variables	Range	Variance	Standard Deviation
Product Quality	5.0	1.950	1.3963

Answer 1

Solution:

In the given output the variable under consideration is "Product Quality". For the given variable various measures of dispersion have been calculated. The first one is the range and for the given variable, it is 5, which means the difference between the maximum and the minimum value is 5. The variance for the given variable is 1.950, which means the average squared differences of each data point from the mean is 1.950. Also, we are given the standard deviation of the given variable is 1.3963. The standard deviation is the square root of the variance and it also measures the dispersion of each data point from the mean value on average. Since the value of the standard deviation is smaller, so we can expect there is lesser variation in the given responses for the given variable.
