I found the concept on frequency distribution using Google and the search words “frequency distribution” at http://www.mathsisfun.com/data/frequency-distribution.html This website is geared towards younger people and therefore breaks down frequency distribution into very basic terms: values and their frequency (how often each value occurs). The website uses the example of a child’s soccer team and how many goals they scored in recent games. For the assignment this week, I have chosen to use the raw data of shoe sizes of my co-workers and how often these shoe sizes occur and show how to put them into a frequency distribution table. Because there are only 4 females in my division, I have stuck with only the male shoe sizes of 20 co-workers. Raw Data

81011109
98111010
121091011

Each raw data value is now placed into a class. Since my range of data is small, I’m going to use single data values. Distribution Table

9IIII4

11IIII4
12II2
Total: 20

This can also be done in excel by following the instructions for a categorical frequency table for qualitative or discrete data on page 2-15 (49) of our textbook. Taking it a step forward, the information can then be used in a pie chart to visually see the frequency of each shoe size.
