Only 300 teenage respondents? That's not enough to ensure such a conclusion, especially when considering percentages of the whole.

According to the raw data download, there are 365 data points, but 104 answered "I don't use any of these" which are stated to be excluded, so the actual amount of teenage respondents is 261?

You defininately need more than 300. Also you need to make sure you have people from different areas.

One school may be very facebook heavy while another may mainly use twitter.

Hi Max, Survata co-founder here. The 365 respondents were used as the denominator for calculating the % of teens that use a service (like Snapchat) regularly. So that's the sample size for the first chart shown in the link. (The margin of error on 365 respondents is about 5%). Naturally, we had to exclude the respondents who used no social services from the questions that asked about their favorite social service, like the second chart shown in the link.

Hope that helps.

Nevermind teens. I'm 42. I use it with my adult siblings, cousins and friends. It's a delightful way to stay in touch. Sometimes it's a picture of my breakfast, or the weather outside, or our pets, or whatever other amusing moment is going on in our day that we'd laugh about if we were together. The ephemeral nature of the pictures and the ability to scribble on them is just delightful fun.

How does 365 data points give your conclusions any sort of statistical significance? Snapchat's numbers are allegedly over 30M, Facebook's are over 1.2B and Instagram's are 150M.

I suggest reading "How to Lie with Statistics"[1]

Edit: I guess that sounded a little harsh. No doubt, Snapchat's growth has been explosive and if this was just another blog-spam post about that fact, I'd let it be. But you're selling a statistical software! I'd expect better from people who know what they're doing. Also, "How to Lie with Statistics" is a really good book, should be required reading for anyone dealing with numbers. Did not mean that as an attack on your product.

Gallup's daily tracking polls, which offer a +-4% margin of error, are based of 1000 data points (insert complaint about appeal to authority here). While 365 is significantly lower than that, there is nothing wrong with using the data to produce a value and a margin of error/confidence.
