Symmetry And Skewness In Statistics. A set of observations is symmetrically distributed if its graphical representation histogram bar chart is symmetric with respect to a vertical axis passing through the mean. The shape of a distribution refers to the shape of a frequency or relative frequency.
Learn about symmetry and skewness with respect to histograms boxplots and stemplots if you found this video helpful and like what we do you can directly s. Always add the direction when describing a skewed distribution. If the skewness of s is zero then the distribution represented by s is perfectly symmetric.

However not all symmetric data has a bell shape like histogram c does. Always add the direction when describing a skewed distribution. A shape may be described by its symmetry skewness and or modality. Half of all measurements are greater than the mean while half are less than the mean.
