What does a negative kurtosis mean?
It means distribution is flater then [than] a normal distribution and if kurtosis is positive[,] then it means that distribution is sharper then [than] a normal distribution. Normal (bell shape) distribution has zero kurtosis.

Yes, the mean can be negative if the numbers being averaged are negative. For example, if you are averaging temperatures and all of the temperatures are below zero, your a…verage temperature will be a negative number.
I will answer your question in a couple of ways. First as a concept: Kurtosis is a measure of whether the data are peaked or flat relative to a normal distribu…tion. That is, data sets with high kurtosis tend to have a distinct peak near the mean, decline rather rapidly, and have heavy tails. Data sets with low kurtosis tend to have a flat top near the mean rather than a sharp peak. A uniform distribution would be the extreme case. Now as a mathematical formula: For univariate data Y1, Y2, ..., YN, the formula for kurtosis is: where is the mean, is the standard deviation, and N is the number of data points.

Skewness is a measure of symmetry, or more precisely, the lack of symmetry. A distribution, or data set, is symmetric if it looks the same to the left and right of the center …point. Kurtosis is a measure of whether the data are peaked or flat relative to a normal distribution. See related link. By doing a search on the internet, you can find more examples.
It's just a way of saying no. So if you ask a question and somebody tells you "Negative ghost rider.", they're just saying no. They got it from the movie Top Gun.
In probability theory and statistics, kurtosis (from the Greek word κυρτός, kyrtos or kurtos, meaning bulging) is a measure of the "peakedness" of the probability distri…bution of a real-valued random variable. Higher kurtosis means more of the variance is due to infrequent extreme deviations, as opposed to frequent modestly sized deviations. Sometimes kurtosis gets confused with skewness, so I have added links to both these terms.
Depends on the context. It could mean that you owe 16.
It means that it is less than the mean.
That their are none cancerous
It becomes less negative To explain. Lets take a negative, eg -5. If we decrease it by 1, it becomes -6 (where 1 is positive) Thus if we decrease it by -1, it becomes -4 (as t…he -1 is negative) Note that the final number could be positive, For example, if you decrease -5 by -6, you get +1
Negging is a term used by pick up artists such as in the book "The Game" and "The Mystery Method". It means to insult a girl playfully to increase her interest in you.
It means deceleration or slowing down and there is a force operating against the motion.
While skewness is the measure of symmetry, or if one would like to be more precise, the lack of symmetry, kurtosis is a measure of data that is either peaked or flat relative …to a normal distribution of a data set. * Skewness: A distribution is symmetric if both the left and right sides are the same relative to the center point. * Kurtosis: A data set that tends to have a distant peak near the mean value, have heavy tails, or decline rapidly is a measure of high kurtosis. Data sets with low Kurtosis would obviously be opposite with a flat mean at the top, and a distribution that is uniform.
IN statistics yes there is a negative mean. Mean is the average of multiple numbers. Negative is opposite of positive.
In the personal sense, it means something negative in your personality like being negative (pessimistic) or not concentrating in school. In algebra it means a minus number b…elow zero eg. -2 is 2 less than zero. An extra note - if the equation is 5--5 (five minus minus five) then just add five because two minuses or negatives equal a plus or positive. Sorry if I got the wrong meaning of what you asked!
