How do I create a Simple Formula question?

You can create a quiz question with a formula in it.

Note: If you need help adding a mathematical formula in the Rich Content Editor, please see the Math Editor lesson.

Add Question

With the Questions tab [1] selected inside a new quiz, click the New Question button [2].

Select Formula Question Type

Select Formula Question Type

Quiz questions are not automatically numbered for instructors. To add a custom name to your quiz question, enter the name in the question text field [1]. Custom names can help you identify quiz questions more easily. Regardless of the question name, students always see quiz questions in numerical order (i.e. Question 1, Question 2).

Click the drop-down menu and select the Formula question type [2].

Enter number of points the question is worth (quiz totals are calculated based on combined total of questions) [3].

Edit Question Details

Edit Question Details

Type the question prompt text and formula with variables in brackets in the Rich Content Editor [1]. You can include video, images, math equations, or flash activities. Click the Need help? link [2] for more advanced options.

Note: If you need help adding a mathematical formula in the Rich Content Editor, please see the Math Editor lesson. You cannot use the letter "e" as a variable. It is a reserved mathematical constant.

Set Variable Definitions

After you have finished typing the formula in the Rich Content Editor, parameters to define the formula will appear. Set the variable definitions for the formula. Specify the minimum and maximum numbers for variable X [1]. Select decimal places in the drop-down menu [2], and click the Recompute button [3] to verify that Canvas will insert a number into the formula that is within the variable definition.

Set Formula Definitions

Type the formula definition in the formula field [1]. Make sure the formula does not contain any brackets or equal signs. Select the Decimal Places drop-down menu [2] to set the number of decimal places you want used for the result. Select the Save button to save your formula [3].

Set Possible Number of Solutions

Set Possible Number of Solutions

In the Offer field, specify the number of possible solutions you want Canvas to generate [1].

In the error margin of field, enter the margin of error for the student's answer [2]. Responses are based on relative error in addition to absolute error. Margins of error can be created as a percentage or as a point value (up to three decimal places).

Click the Generate button to view final answer [3].

Provide Feedback

Provide Feedback

You can provide feedback for the question by clicking a feedback bubble and entering text. The bubbles are color-coded to correspond with the type of answer the student provides. Green is for correct answer feedback [1], red is for incorrect answer feedback [2], and blue is for general question feedback [3].
