How to Use the Random Number Table
To use the random number table, enter the table at a random point. The easiest way to do this is by closing your
eyes and placing your finger on the table. The column and row nearest your finger is the starting point. Determine
how many digits in the row you are using: if you need numbers between 1 and 250, use three digits in the row. If you
need numbers between 1 and 25, use two digits in the row, and so on. Decide in which direction you will move
through the table. Then proceed in any direction through the table (even diagonally), recording appropriate numbers
and skipping numbers too high or repeated, until you have enough random numbers. You should decide on a
direction and enter the table at a different random starting point every time you use it.
For example, if you need to choose 3 numbers between 1 and 25, you could enter the table by placing your finger on
the table to choose a column and row. Your criterion is two digit numbers between 01 and 25 (inclusive). For this
example, you decided to work up the column from your starting point. As you move up the column, the first
number you encounter is 14. This is a two-digit number between 01 and 25; it fits the criterion, so you write it down.
The next number is 09; it also fits the criterion, so you write it down. The next number is 58 and does not fit the
criterion so you skip this number. Keep moving up the column, skipping the numbers that do not fit the criterion,
until you choose the all the numbers you need.
