As designers, we love flat design and grayscale aesthetics. But back in Photoshop, when we were working on bolder design, we would often use a technique called stem and leaf to create a dramatic presentation that respects both design rules and the canvas. Stem and leaf lets you create a design that has depth, texture, and color in one stroke of a brush.


We have already learned about the median, the mode and the mean but sometimes these don't fully describe a set of data. We then need to use the measure of variation e.g. if we have the two number series A (10, 23, 50, 72, 90) and B (48, 49, 50, 51, 52) we can see that they both have the same median, but that there is a huge difference in variation.

Stem and Leaf Plot Graphing: It is a specific table used to showcase the data in the interesting way. Here each digit in the data is split into a stem (1st digit(s)) and leaf (last digit(s)). It plots data similar to the horizontal bar graph but uses the original data instead of bars. The stem and leaf plot is similar to histogram in displaying the statistical data.

There are five important values to remember if you want to divide your data into quartiles. The lowest and the highest values are our lower and upper extreme values. The median divides the data into two equally sized parts with 50% of the data points on each side. The other two values to remember are the lower quartile (LQ), which divides the lower 50% of the data points into two equally sized parts, and the upper quartile (UQ), that separates the higher 50% of the data points into two equally sized groups.
