It can be negative, zero or positive.
Correct.
if it didn't equal zero then what else would it equal
A scalene triangle has zero equal sides.
Kurtosis is a statistical measure used to describe the shape of a probability distribution's tails in relation to its overall shape. It quantifies the "tailedness" or the extent to which data points deviate from the mean, specifically focusing on the presence of outliers. Higher kurtosis indicates heavier tails and a sharper peak, suggesting a higher probability of extreme values, while lower kurtosis indicates lighter tails and a flatter peak. Understanding kurtosis helps analysts assess risk and variability in data distributions.
The Greek word "kurtosis", when translated to English, means the probability theory of any measure of the "peakedness" of a real valued random variable.
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.
No. Skewness is 0, but kurtosis is -3, not 3.No. Skewness is 0, but kurtosis is -3, not 3.No. Skewness is 0, but kurtosis is -3, not 3.No. Skewness is 0, but kurtosis is -3, not 3.
Kurtosis is a measure of the "peakedness" or thickness of the tails of a distribution compared to a normal distribution. A positive kurtosis indicates a distribution with heavier tails and a sharper peak, while a negative kurtosis indicates lighter tails and a flatter peak. Kurtosis helps to understand the shape of a distribution and the likelihood of extreme outcomes.
Zero is equal to zero
Any number to the power zero is equal to 1 - except zero to the power zero, which is undefined. So, if x is not equal to zero, the answer is 1.Any number to the power zero is equal to 1 - except zero to the power zero, which is undefined. So, if x is not equal to zero, the answer is 1.Any number to the power zero is equal to 1 - except zero to the power zero, which is undefined. So, if x is not equal to zero, the answer is 1.Any number to the power zero is equal to 1 - except zero to the power zero, which is undefined. So, if x is not equal to zero, the answer is 1.
Any number multiplied by zero is equal to zero, including zero. Therefore, zero times zero is equal to zero. 0 x 0 = 0
How can a class frequency be equal to zero?
Yes most of them do equal zero.
A polynomial is identically equal to zero if and only if all of its coefficients are equal to zero. eg. The power series on the left is identically equal to zero, consequently all of its coefficients are equal to 0:
Correct.
if it didn't equal zero then what else would it equal
No, zero divided by four is not equal to four. It's actually equal to zero. In fact zero divided by any number is equal to zero, except for zero divided by zero because you can't divide by zero.
