I had already finish the survey part of my project. In order to save time, I decide to conduct a online survey rather than distributing in the street.

Here is my online survey:

https://docs.google.com/forms/d/130Y2nObPpDxuyr2eQkoYJ6QCRGYsJjY3bn3rZV2j60o/viewform#start=openform 

I had successfully obtained about 50 results.

Now, I am analyzing the above responses and also recruiting the focus group people at the same time. As google already helps me to display all the data as a simple pie chart. It makes me easier to understand the distribution of the participant's gender, age and profession. The next step is to create some tables in order to show the relationship between different variables. For example,  I compare the question "How much time did you spend on Facebook yesterday?" with "Which of the following functions of Facebook are you interested in? ". It can help me understand whether the frequency of visiting Facebook affects the reasons why people come to this site. However, I am not really sure about my analysis methods.
