Which of the following is not true about skewness?
|
A negative value near -3 shows that the distribution is considerably right-skewed. |
|
The skewness gives information about the shape of the distribution. |
|
If the distribution is unimodal, the mean, median and mode are the same. |
|
If the distribution is left-skewed, having a long tail in a negative direction and a single peak |
|
Pearson’s coefficient of skewness (PCS) can take values between -3 and 3. |
Pearson’s coefficient of skewness (PCS) can take values between -3 and 3. A negative value near -3 shows that the distribution is considerably left skewed and a positive value near 3 shows that the distribution is considerably left-skewed. If the PCS is near zero, this indicates that the distribution is symmetric because in this case the mean, the median, and the mode are similar.
