Today we are going to talk about right skewed histogram, friends it is a very important concept for data visualization.
- Right Skewed
There are two main types of skewness in histograms, right and left. The skewed right histogram is one in which the tail is on the right side. The skewed left histogram is one in which the tail is on the left side. The below histogram is a skewed right.
- Positive Skewness
A graph which has positive skewness, the mode is usually less than the median and mean.
- Uniform Histogram
You can see the Bimodal histogram in this black and white graph, it is actually having two modes. If there is one peak, it is uni-modal and if there are two peaks, it is called bimodal. Uni means only one mode and bimodal means two modes. You can see the graph having two peaks, which means it has two modes. Sometimes histogram is bimodal and skewed right. You can see it in the last image on right hand side.
