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
What are the measure of skewness?
Skewness is a statistical measure that quantifies the asymmetry of a probability distribution about its mean. It can be classified as positive, negative, or zero. Positive skewness indicates that the tail on the right side is longer or fatter, while negative skewness signifies a longer or fatter tail on the left side. A skewness of zero suggests a symmetrical distribution.
What type of information is involve with skewness?
Skewness measures the asymmetry of a probability distribution around its mean. It indicates whether the data is skewed to the left (negative skewness) or to the right (positive skewness), providing insights into the shape of the distribution. A skewness value close to zero suggests a symmetrical distribution, while values further from zero indicate greater asymmetry. Understanding skewness helps in assessing the data's characteristics and can influence statistical analyses and interpretations.
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.
How do you calculate Pearson's skewness coefficient?
Pearson's skewness coefficient can be calculated using the formula ( \text{Skewness} = \frac{3(\text{Mean} - \text{Median})}{\text{Standard Deviation}} ). First, find the mean and median of the dataset, then compute the standard deviation. Finally, substitute these values into the formula to obtain the skewness coefficient, which indicates the asymmetry of the distribution. A positive value indicates right skewness, while a negative value indicates left 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 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.

Notes about Bowel's coefficient of skewness and Kelly's coefficient of skewness?
describe the properties of the standard deviation.
What is Pearson's first rule of the measure of coefficient of skewness?
skewness=(mean-mode)/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
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.
