Question

consider the graph below. cost of electricity, kwh how are the data skewed in the graph above? negatively there is not enough data to find a skew positively symmetrically

Explanation:

Step1: Recall skewness concept

Skewness refers to the asymmetry in a distribution. Positive - skew means the tail on the right side of the distribution is longer, negative - skew means the left - hand tail is longer, and symmetric means both tails are of equal length.

Step2: Analyze the bar - graph

In the given bar - graph of the cost of electricity over the years, we observe that the values increase over time and the higher values (on the right side of the graph in terms of the year variable) are more spread out. The tail on the right side of the distribution of cost values is longer.

Answer:

Positively
