A skewed graph is a type of graph where the data is not evenly distributed around the mean, resulting in an asymmetrical shape. There are two types of skewness: positive and negative. In a positively skewed graph, the tail of the graph is longer on the right side, while in a negatively skewed graph, the tail is longer on the left side. They may also cover important details or trends in the data. Presenters should take care to accurately represent the data and choose appropriate graph types that best display the information. The apt representational graph helps to clarify the data and minimize any potential confusion or misinterpretation.
