The process of identifying the skew of a data set is essentially an exploration of its asymmetry. When we see a positive skew, it indicates that the data leans towards the right, characterized by a lengthier tail on its right side. Conversely, a negative skew points to a leftward tilt. A lack of skewness, on the other hand, denotes a balanced or symmetrical distribution. Understanding the skewness of a data set is key in comprehending data distribution overall.
