Figure 4
The distribution grid is shaped like a symmetrical stepped pyramid sitting on a horizontal axis. The horizontal axis ranges from “negative 5” on the far left to “5” on the far right in increments of 1. Below the numerical labels, text labels read “Disagree” under “negative 5”, “Neutral” under “0”, and “Agree” under “5”. The grid is composed of stacked rectangular blocks. At the scale values of “negative 5” and “5”, there is one block. At “negative 4” and “4”, there are two stacked blocks. At “negative 3” and “3”, there are two stacked blocks. At “negative 2” and “2”, there are three stacked blocks. At “negative 1” and “1”, there are four stacked blocks. At the center value of “0”, there are five stacked blocks.Example of fixed quasi-normal distribution
