The software uses the standard width to make an adjustment to the heights of the histogram bars, incorporating the fact that not all the classes have equal width. In the case when not all the classes have equal width, set the standard width to be equal to any one of the class widths, for example the smallest class width or the largest class width or the most common class width. In the case when all the classes have equal width, set the standard width to be equal to this unique width of the classes. For example, the width of the first class is 5-1=4 the width of the second class is 10-5=5, and so on. Step 2: Set the standard width.įirst of all, the class width is the difference between the upper boundary and the lower boundary. In case you have less than 15 classes, just leave the remaining rows blank. The input table accepts up to 15 classes (i.e. In the default example provided, the upper boundary of the first class is 5 which is equal to the lower boundary of the second class (which is also 5). This ensures that the histogram has all its bars touching. Note that the upper boundary of a class must be equal to the lower boundary of the next class.

Each row corresponds to a class and thus will be represented by a bar in the histogram. Insert the frequency table in the table input provided.
