Add a calculation question

For a calculation question, after the survey is completed Profit calculates a value based on a number of other questions. Profit can determine the average, the average deviation of the the average, the sum, the highest value and the lowest value.

You can only calculate a value for choice and multiple choice questions. These are questions with a selection group linked to them. For each choice in a selection group, you can specify a score. Profit uses the score to determine the result of the calculated question. For multiple-choice questions, Profit uses all answers and the associated scores in the calculation. A multiple-choice question is a question to which the respondent can give multiple answers.

Example:

You conduct a survey to measure the use of certain products. For each question you use the following selection group (although you can also use different selection groups):

• I do not use this product (score: 0)
• This year, I have used this product 1 - 10 times (score 5)
• This year, I have used this product 11 - 30 times (score 10)
• This year, I have used this product over 30 times (score 20)

  You use a calculation question to determine the average of all questions related to product use. After the survey has been completed, Profit determines the average of the above scores per respondent. The higher the average score, the more a product is used on average.

You add both the calculation question and the questions to be answered to the survey model. The calculation question is not shown in the survey as it is displayed for the respondent.

If a calculated question forms part of a survey model, Profit always calculates this, even if not all the underlying questions are part of the survey model. Profit uses the results of the questions linked to the survey model.

To add a calculation question:

1. Go to: General / Survey / Configuration / Question.
2. Click on: New. 
3. Go through the steps of the wizard for adding a question.
4. Select the question type Calculated question.
5. Select the Calculation you want to perform.
   • Average deviation from the average (standard deviation)

     Profit determines the average and then determines how much each score deviates from the average. Then the average of the deviations is calculated.

   • Average
   • Highest

     Profit determines the highest value of the scores.

   • Lowest

     Profit determines the lowest value of the scores.

   • Total

     Profit determines the total value of the scores.

6. Specify whether questions that have not been answered should be included when determining the result of the calculation question.
7. Select the rounding of the calculated value. Most of the choices are fairly straightforward and are not explained here.

   Example: 

   The calculated value is 7.15.

   For Round to half numbers upwards, this value will be rounded to 7.5.

   For Round to half numbers downwards, this value will be rounded to 7.0.

8. Click on: Finish. 
9. Open the properties of the question you just added.
10. Go to the tab: Calculate from questions.
11. Click on: New. 
12. Select the desired questions.

    Profit performs the calculation using these questions.

13. Click on: Finish.
