A numeric-response question is a question for which students must provide the correct numeric answer.

To create/edit a numeric-response question:

1. Edit an existing numeric-response question or click the New Question button and choose Numeric Response.

2. Enter a question Title.
   Note: When creating a new question, if you do not enter a question Title, it will auto-populate with the stem of the question when you click OK. If you do not want the Title to auto-populate for new questions, deselect the Automatically populate question titles option in your profile.

3. Enter the question content in the word processor window.

4. Click the Answer tab and enter the correct answer in the word processor window.

   • To require students to indicate units in their answer when taking the test electronically, select the Include units requirement option.

   • You can enter a range of correct answers (see below). If you are using a range of correct answers, Restrict to numeric only must be selected.

   • You can enter multiple correct answer on separate lines.

   • You can enter **Any answer accepted** and students will receive credit for the question regardless of what they enter.

5. Set the appropriate options in the Response / Entry Mode section to choose how answers will be entered in electronic tests.

   • Restrict to numeric only -- Students can only type the following: 0 1 2 3 4 5 6 7 8 9 - + e0 , .
     
     Note: The e and + are only acceptable in scientific notation (for example, 2e+2 to express 200). A - is only acceptable as a negative sign before a number or in scientific notation (for example, -2 or 2e-2 to express .02).
     
     If you are using a range of correct answers, this option must be selected.

   • Fractions -- Students will receive numerator and denominator fields.

   • Include whole number field -- Students will receive a whole number, numerator, and denominator fields.

6. (Optional) Click the Grading tab to select how to perform automatic grading for electronic tests.

   • Select Arithmetic equivalence to mark answers correct if the student enters an answer that has an arithmetic value that is equivalent to the correct answer but is not an exact match.
     
     Note: If you are using a range of correct answers, this option must be selected.

   • Select Require exact decimal places to require students to include the specified number of decimal places in order for their answer to be correct.

   • Select Require exact significant figures to require students to include the specified number of significant figures specified in order for their answer to be correct.

   • Select Strict/exact to require the student’s answer to exactly match the answer, including commas and decimal points.

   • Select None (subjective) to allow the student enter text and/or numbers, and the question will be graded manually.

7. (Optional) Enter a Points value.

8. (Optional) Click the Rationale tab to enter the reasoning behind the question or detailed information on the solution.

Answer Ranges

On the Answer tab you can enter a range of acceptable values. You can enter answer ranges as a simple inclusive range or a complex range.

Simple Inclusive Range

For a simple range, you can enter the beginning and end of the range separated by ellipsis (...). For example: 1...10. When separating the values with an ellipsis both numbers are included in the range. If you enter 1...10, then an answer between 1 and 10, including 1 and 10, will be accepted as correct.

Complex Range

You can also enter a range within brackets [ ] or parentheses ( ) with the two limits separated by a common. Use brackets to indicate that a number is included in the range or parentheses to indicate that a number should not be included. For example: (1, 10) or [-5.2, 6.3] or [20, 30) or (15, 80].

• • [1, 10] - Answers between 1 and 10, including 1 and 10, are correct. This is the same as the simple inclusive range of 1...10.

  • (1, 10) - Answers between 1 and 10, not including 1 or 10, are correct.

    • 1 or 10 would be wrong.

    • 1.0001 or 9.9999 would be correct.

  • (1, 10] - Answers between 1 and 10, not including 1, are correct.

    • 1 would be wrong.

    • 10 would be correct.

    • 1.0001 would be correct.

  • [1, 10) - Answers between 1 and 10, not including 10, are correct.

    • 1 would be right.

    • 10 would be wrong.

    • 9.9 would be right.

Caution:

• • To use a range of answers, Restrict to numeric only must be selected on the Answer tab.

  • Arithmetic equivalency must be selected on the Grading tab.

  • Questions with a range of values will not work if exported for an LMS.
