Bar graph for starting salary data. Another type of graph used to represent a frequency table is the frequency polygon, which plots the frequencies of the different data values on the vertical axis, and then connects the plotted points with straight lines. Figure 2.3 presents a frequency polygon...
A frequency distribution table in which we group the data is known as a grouped frequency distribution table. The table is based on the frequencies of class intervals. All the categories of data are divided into different class intervals of the same width, for example, 0–5, 5–10, 10–15...
