Show answer & explanation
Correct answer: A
To understand what a skewness of 0 indicates in a dataset, we need to look at the symmetry of the data distribution.
Analysis of Skewness
Skewness is a measure of the asymmetry of a probability distribution about its mean.
Skewness = 0: This indicates that the distribution is symmetric. In a symmetric distribution, the data is evenly distributed on both sides of the mean, meaning the left and right sides of the distribution are mirror images of each other.
Positive Skewness (> 0): This indicates a longer or fatter tail on the right side of the distribution.
Negative Skewness (< 0): This indicates a longer or fatter tail on the left side of the distribution.
Correct Option
Option A: The dataset is symmetric
