The use of Pearson Coefficient of Skewness?
the use of the pearson's of skewness
If coefficient of skewness equals 0 then what would you say about the skewness of the distribution?
if coefficient of skewness is zero then distribution is symmetric or zero skewed.
What is the difference between Dispersion and Skewness?
distinguish between dispersion and skewness
How do you calculate skewness?
Skewness is measured as the third standardised moment of the random variable. Skewness is the expected value of {[X - E(X)]/sd(X)}3 where sd(X) = sqrt(Variance of X)
How skewness help in determining relation between different measures of central tendency?
Negative skewness means the average (mean) will be less than the median. Positive skewness means the opposite. I'm not sure if any rule holds for the mode.

What is the values of the skewdness and kurtosis coefficient for the normal distribution 0 and 3 respectively?
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.
What is Pearson's first rule of the measure of coefficient of skewness?
skewness=(mean-mode)/standard deviation
Notes about Bowel's coefficient of skewness and Kelly's coefficient of skewness?
describe the properties of the standard deviation.
When the data are skewed to the right the measure of Skewness will be?
When the data are skewed to the right the measure of skewness will be positive.
Can you compare and contrast the skewness and normal curve?
Answer this question...similarities and differences between normal curve and skewness
How do you calculate skewness?
Skewness is measured as the third standardised moment of the random variable. Skewness is the expected value of {[X - E(X)]/sd(X)}3 where sd(X) = sqrt(Variance of X)
What is the definition for skew in math terms?
The skewness of a random variable X is the third standardised moment of the distribution. If the mean of the distribution is m and the standard deviation is s, then the skewness, g1 = E[{(X - m)/s}3] where E is the expected value. Skewness is a measure of the degree to which data tend to be on one side of the mean or the other. A skewness of zero indicates symmetry. Positive skewness indicates there are more values that are below the mean but the the ones that are above the mean, although fewer, are substantially bigger. Negative skewness is defined analogously.

Negative skewness means the average (mean) will be less than the median. Positive skewness means the opposite. I'm not sure if any rule holds for the mode.
Is not a characteristics of a normal distribution.?
Skewness is not a characteristic.
