Question

If the Pearson coefficient of skewness for a data set is -1.229 , what can be concluded about the data set?

a. The data is skewed to the left since −1.229<−1.
b. The data is skewed to the right since −1.229<1
c. The data is approximately normal since −2<−1.229<2.
d. The data is skewed to the right since −1.229<0.
e. The data is approximately normal since −2<−1.229<0.
f. The data is skewed to the left since −1.229<0.

Answer 1

The given data set is skewed to the left.

Step-by-step explanation:

The given Pearson coefficient of skewness for the data set is -1.229. Since the coefficient is negative, we can conclude that the data set is skewed to the left. Therefore, option a: The data is skewed to the left since -1.229 < -1, is the correct answer.
