STEP-BY-STEP TECHNOLOGY GUIDE: Runs Test for Randomness

14-61

TI-83/84

The TI-83/84 calculators and Excel do not have a built-in function for the runs test for randomness.

MINITAB

Minitab can perform the runs test for randomness for numerical data only.

  • Step 1 Enter the numerical data in column C1.
  • Step 2 Click Stat > Nonparametrics > Runs Test….
  • Step 3 For the variable, type C1. Select Above and Below, and enter the value that is used to classify the data into two distinct categories. For example, in Example 26, we would enter 0 here, because values above 0 are positive and values below 0 are negative. Click OK.

SPSS

SPSS can perform the runs test for randomness for numerical data only.

  • Step 1 Enter the numerical data in the first column.
  • Step 2 Click Analyze > Nonparametric Tests > Legacy Dialogs > Runs….
  • Step 3 Move the first column to Test Variable List. For Cut Point select Custom, and enter the value that is used to classify the data into two distinct categories. Click OK.
