Is it possible to compute a negative variance

My question is thus, what could have happened that would cause the variance to be a negative number? I know I cannot be much help by displaying the actual data here because of problems with formatting, but here are the column names and what I named them as:.

Some of these differences can be and — unless all the numbers are exactly the same — will be negative. Then you square each of the differences multiply it by itself. This is precisely the moment which eliminates the possibility of variance and therefore also standard deviation being negative.

Something negative or positive number squared is always a positive number, except zero squared which is still zero. Because the squared deviations are all positive numbers or zeroes, their smallest possible mean is zero. This average of the squared deviations is in fact variance. Can the standard deviation ever be negative? What is the sample standard deviation formula? What is the symbol for the sample standard deviation? What are the symbols for the sample variance and for the population variance?

Which data set has a larger standard deviation? Besides the above, what does a negative standard deviation mean? The question then is: how do you find the variance of a negative number? What does it mean if a month or season shows negative variance? What are the main causes of variance?

Can variance be negative? What does a positive deviation indicate? How are deviations determined? What is the percentage of the deviation? Is the deviation always positive? Is the variance budget really negative? Why is variance always positive? Can a standard deviation be negative? Can a cure be bad? The normal distribution has no inherent bias for a positive or negative mean. How do you find the growth rate of a negative number? How do you find the percentage deviation?
