Skewed frequency table
WebbA distribution is said to be skewed if the curve shifts to right or left from a normal bell-shaped distribution. The symmetrical curve has zero skewness. That is the normal distribution has a skew of zero. A skewed distribution has a tail at either of the sides. A tail refers to the tapering off on one side of the graph.

If it doesn't affect your business logic, you can filter the higher-frequency values in advance. For example, if there are many 000-000-000 in column GUID, you might not want to aggregate that value. Before you aggregate, you can write “WHERE GUID != “000-000-000”” to filter the high ...

WebbSteps to draw a histogram: Step 1: On the horizontal axis, we can choose the scale to be 1 unit = 11 lb. Since the weights in the table start from 65, not from 0, we give a break/kink on the X-axis. Step 2: On the vertical axis, the frequencies are varying from 4 to 10. Thus, we choose the scale to be 1 unit = 2.
