Respuesta :

The pearson's coefficient of skewness is found as the 1.065.

What is termed as the coefficient of skewness?

  • The coefficient of skewness is a measurement used to evaluate the strength and direction of skewness in a sample distribution using descriptive statistics such as mean, median, or mode.
  • The skewness coefficient is used to compare a distribution of the sample to a normal distribution.

Pearson skewness:

The skewness of the a data set is calculated by subtracting the mean from the median and dividing by the standard deviation.

In this case:

The mean is 95, the median is 77, as well as the standard deviation is 16.9. So,

Pearson skewness = (95 - 77)/16.9

Pearson skewness = 1.065.

Thus, the pearson's coefficient of skewness is found as the 1.065.
