Ideally, you have a column containing the different groups (\"0 to 9 customers,\" \"10 to 19 customers,\" \"20 to 29 customers\" and so on in the number of customers example) and the frequencies of observations in the next column. 2. 5. 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. MEMORY METER. To draw frequency polygons, first we need to draw histogram and then follow the below steps: Step 1-Choose the class interval and mark the values on the horizontal axes; Step 2-Mark the mid value of each interval on the horizontal axes. Seeing the data in this format helps us visualize and understand it better. Minutes late. Don't know arc functions to perform it though.
