Correct Answer � B Explanation

Ans: B. 1-Normal distribution, 2-Negative skewed, 3-Positive skewed

Positive or negative skewed data:

• Defined by the direction of the tail, i.e. direction of the least frequency values.
• Similarly in this box plot, we can see that the data is equally distributed on either side of the mean box in Plot (1).
• In Plot (2), the median is towards the higher side and most values are distributed towards the higher side hence it is negatively skewed.
• Hence, vice versa for Plot (3).
