Measures of Shape

Skewness provides a measure of the shape of data. Adrian describes this statistic in this video.

We introduce the idea of ‘skewness’ in this video.

Skewness tells us about the symmetry of the distribution of data. Skewness of 0 means that the data is perfectly symmetric, so you can draw a vertical line and both sides of that line would look identical. Positive and negative skew indicate that the distribution is not symmetric, with tails either to the right or left.

In the next step, we demonstrate how to calculate the measures introduced so far using Excel.
