WebbLesson Worksheet: Histograms and Frequency Polygons. In this worksheet, we will practice drawing histograms and using histograms to analyze data, communicate information, and get insights from data. The grouped frequency table represents the amount of time, in minutes, students take to walk to school. Find the frequency density … WebbTo make a histogram by hand, we must first find the frequency distribution. The idea behind a frequency distribution is to break the data into groups (called classes or bins) so that we can better see patterns. It is sort of like the difference between asking you your age and asking you if you are between 20 and 25.
