Are you a man or a woman?
As you can see, the division man/woman is not exactly 50/50. However, within our 129 respondents, 44,1% is a woman against 55,9% men; this is pretty decent. It’s quite hard to achieve a 50/50 division between men and women. In order to achieve this, the number of respondents must be very large.

What is your age?
When taking a look at age, the first thing that stands out there is a pretty big group of 18-25-year-olds. This can be explained by the fact that the survey was for a big part spread under students. Disregarding the fact that a group of 18 to 25-year-olds is a bit overrepresented, there is a decent spread of age categories. People from fairly every age category are present in the research population. This makes the survey more valid.
When analyzing the highest level of education that our respondents have followed, we again see a fairly decent spread of answers. We have a fairly high percentage of HBO (applied sciences). However, this shouldn’t really be a problem, as other groups are represented as well.

What is the highest level of education that you attended?

Respondents provided us with the following answers: Blue is a high school student, green is a student in a university, HBO or MBO, yellow is a working person and orange is ‘something else’. The majority of our respondents is working.
What is your current profession?

We can conclude that 38,5% of respondents encounter this problem relatively frequently.
How often do you encounter the problem of a bottle not fitting under the sink?

This is another important question for our questionnaire. Respondents could respond in 5 different ways: Blue means yes, Green means probably yes, yellow means maybe, Pink means probably not and orange means no. The results show us that 54,3% of respondents consider buying a bottle that solves the sink problem.
Would you buy a drinking bottle that solves the sink-problem?

The results of this question are quite remarkable; no respondent wants to pay more than €20 for a drinking bottle. It’s probably smart to make sure that our bottle does not cost more than €20.
What is the maximum amount of money you would pay for a bottle that solves the problem mentioned earlier?

It’s pretty clear that most respondents prefer a bottle that is 500 mL in size. This is the size we’ll be aiming for.
What is the preferred volume of a drinking bottle for you personally?

How important do you consider the following in the design of a drinking bottle?
This question is a bit more complex; respondents had to rank some aspects of a drinking bottle from not important at all to very important. We offered the respondents four aspects: functionality, A striking color, a minimalistic design and a unique design.
This resulted in some pretty logical answers. Respondents valued the aforementioned aspects of the bottle in order of preference as follows:
1. Functionality
2. Minimalistic design
3. Unique design
4. Striking color
Where functionality was by far the most preferred aspect
