Problema Solution
Is the range for a set of measurements greater than or equal to 0? Explain
Is the sample standard deviation a positive real number? Explain
Answer provided by our tutors
The range of a set of measurement is calculate by subtracting the maximum value of the set and the minimum value of the set, thus it il, always be great or equal to 0.
Standard deviation could be roughly defined as the distance between a value in the set and the median of the set. Thus it can be either negative or positive, depend on whether the value selected is greater or less than the median.
