Select the type of statistical experiment you want to do. If you want to take a sample of all the different sports played in the U.S., then you will use a nominal scale.
Separate the different sports categories by name on your sheet of paper. As an example, the first will be baseball, then football, basketball, soccer, and so on.
Use this list as the starting point and scale for whatever studies you wish to further conduct. The scale could have been anything, including types of teas or varieties of apples.
Select the type of statistical experiment you want to do. If you want to measure the order of your experiment by rank, with one being the most used or in demand and 10 being the least used or in demand, then you will use an ordinal scale.
Write the numbers 1 through 10, starting from the top and going down, leaving some space between each on your sheet of paper.
Use this list as the starting point and scale for whatever studies you wish to further conduct. The experiment can also be broken down into ranks by ordinal name, such as "excellent," "satisfactory" and "poor."
Select the type of statistical experiment you want to do. If you want to measure the order of your experiment according to intervals, for example the average temperature of countries around the world using a Fahrenheit measure from 0 degrees to 100 degrees, then you can use an interval scale.
Write the numbers 0-10 degrees, 11-20 degrees, 21-30 degrees and so forth until 100 degrees, starting from the top and going down, leaving some space between each on your sheet of paper.
Use this list as the starting point and scale for whatever studies you wish to further conduct. You may place each country name next to the correspondent temperature interval.
Select the type of statistical experiment you want to do. If you want to measure a result against a changing factor, for example prospective company income per number of workers, then you can use a ratio scale.
Write the numbers: 10 workers, 20 workers, and 30 workers, starting from the top and going down, leaving some space between each on your sheet of paper.
Use this list as the starting point and scale for whatever studies you wish to further conduct. You may place each calculation of company revenue next to the 10, 20, and 30 scales, signifying how much income is derived with every 10, 20, and 30 workers.
