Frequency Distribution
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
10 12 9 10 11
8 10 11 10 9
9 8 11 10 10
12 10 9 10 11
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
Class Limits Tally Frequency
8 II 2
9 IIII 4
10 IIII IIII 8
11 IIII 4
12 II 2 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
