Aim of the
tool |
|
|
The aim of
surveylength is to provide an estimation of the median length of an
online questionnaire. |
|
|
|
|
|
Lower and
Upper estimates |
|
| |
As it is very unlikely
to get an estimate precise to the second, the lower and upper estimates
around the estimated length indicate that in all probability, the
length of your survey should range between these two estimates. |
|

Section
«YOUR RESPONDENTS» |
|
|
|
In this section you
have to describe the structure, age and language of the respondents who
will answer the survey. |
|
|
|
|
|
|
Age of the
respondents |
|
| |
|
By default, the
percentage of respondents in each age category is fixed to 12.5%. You
can modify this repartition according to the age structure of the
respondents you need for your study. |
|
|
|
|
|
Number of
respondents |
|
| |
The number of
respondents who are going to take part in your survey has an influence
not on the average estimated length of your survey, but on the lower
and upper estimates of this duration. The more respondents, the smaller
the time interval around the estimated length |

Percent of
respondents by path |
|
| |
Many surveys contain
« filter questions », which means than some respondents will
have to answer more or less questions than others to reach the end of
the survey. For example, only respondents who gave a low answer to a
satisfaction question may be asked to explain why they are unsatisfied.
In order to deal why such « filter questions », you have the
possibility to indicate up to 3 different paths that respondents may
have to follow. A path corresponds to a defined number of questions
respondents will have to answer.
For example, within the same survey, 70% of your respondents may have
to answer on average 10 single closed-ended questions and 1 open-ended
question (= path 1), and 30% may have to answer on average 20 single
closed-ended questions and 3 open-ended questions (= path 2). You can
therefore indicate that 70% of your respondents will have to go through
path 1, and 30% will have to go through path 2. |
|
|
|
|
|
Type of
questions |
|
| |
Here you have to
indicate for each question type how many questions of that type are to
be found in each path of your questionnaire. |
|
|
|
|
|
Single closed-ended
questions |
|
| |
Single closed-ended
questions are all types of questions where respondents have to choose
one or several answers in a predefined set of answers.
|
|
| |
|
|
|
Examples of single
closed-ended questions: |
|
|
|
|
|
On a scale from 1 to
9, how satisfied are you with your purchase? |
|
|
|
|
|
Matrix table questions
|
|
|
Matrix table questions
are used when respondents have to answer several questions using the
same answer scale. |
|
|
|
|
|
Examples of matrix
table questions: |
|
|
|
|
|
| |
How satisfied were you
with the following aspects of the service? (scale from 1 "not at all
satisfied" to 5 "completely satisfied") |
|
|
- Speed of resolution |
|
|
- Knowledge of
representative |
|
|
- Solution offered |
|
|
- Friendliness of
representative |
|
|
|
|
| |
For this question
type, you have to indicate the total number of items/question that
respondents have to answer within all matrix tables. In this example,
the number of items/questions respondents have to answer is 4. |
|
|
|
|
|
|
Questions with
multiple choices |
|
| |
|
A question wit
multiple choice is a simple, closed-ended question type that lets
respondents select one or multiple answers from a defined list of
choices. |
|
|
|
|
|
|
Ranking questions
(drag-n-drop/drag-ranking, click-ranking) |
|
|
|
A ranking question
asks respondents to compare items to each other by placing them in
order of preference. |
|
|
|
|
|
|
Open-ended questions |
|
|
An open-ended question
is a question that respondents have to answer by using (and writing)
their own words. |
|
|
|
|
|
Examples of open-ended
question: |

Text only |
|
| |
Sometimes respondents
have to read a text before or instead of answering a question. To
estimate how long respondents need to read a text, count the number of
words the text contains and enter the result in "text 1, number of
words". (A quick way to count the number of words of a text is to copy
and paste the text in a word document.) |
|
|
|
|
|
Personalized questions |
|
| |
Certain complex
questions may necessitate more time to answer than the standard type of
questions described above. For example, respondents may have to watch a
short movie, they may have to read a long text first, make a
complicated calculation, etc.
It is difficult to estimate the time needed to answer such questions
without knowing the question itself. If you want to take such questions
into account in your estimation, go through the following two steps:
1/ indicate in “type 1: number” how often respondents will have to
answer this or a similar question.
2/ indicate in “type 1: duration” your best estimate of the time
respondents will take to answer this question. |
