Grouped Frequency Distributions. When there is a large number of potential scores, it is useful to group them into a manageable number of intervals (around 10 to 20) by creating intervals of equal widths and computing the frequency of scores that fall into each interval. Such a distribution is called a grouped frequency distribution. So what we’re going to make is a grouped frequency distribution table. But how do we group them? What we do is pick two numbers, one called the lower limit of the first class, and one called the class width, such that if we all use these numbers, and use them correctly, we’ll get identical tables. How to construct a frequency distribution table of quantitative data, in particular choosing your class width and figuring out your lower and upper class limits.
