When most of the data is on the left side of the histogram, and yet a few bigger values are on the right, the data will be skewed just on right, and the further discussion can be defined as follows:
This same <u><em>median is smaller than the median</em></u> whenever the data is skewed to the left.
When the data is symmetric, it has the same form on either side of the center.
The distribution is right-handed and right-skewed (also known as "positive-skewed" distribution), the majority of the data is on the right or positive side.
The histogram is therefore skewed to the degree that its right (or "tail") is <em><u>longer than the left</u></em>.
