Skewed graph
Skewness measures symmetry of the distribution. When the median is closer to the top of the box and the whisker is shorter on the upper end of the box the distribution is left-skewed or negatively skewed.
It looks like a slope that moves up fastly and then gradually.
. Skewed data is data that creates an asymmetrical skewed curve on a graph. A right-skewed histogram looks like a graph that reaches the maximum point of its slope before the center point of the graph. In statistics the graph of a data set with normal distribution is symmetrical and shaped like a bell.
It is the extent to which the distribution varies from a normal distribution. Skewness is the measure of asymmetry or distortion to the symmetric bell-shaped graph in a set of data. If we move to the right along the x-axis we go from 0 to 20 to 40 points and so on.

In scientific applications skewed data is common and the usual solution is to plot the logarithm of the values. Bar chart plotting skewed with logarithmic axis. Therefore right skewness is positive.
So towards the right of the graph the scores become more positive. If skewness is positive value than we talk about right. Normal distribution has skewness of zero.
In graph theory a branch of mathematics a skew-symmetric graph is a directed graph that is isomorphic to its own transpose graph the graph formed by reversing all of its edges under an. Left-skewed distribution also called negatively skewed distribution refers to a situation when the chart has a longer tail in the negative direction of its number line.
