Yeah, as far as i know, the sample size of their survey is good enough. I'm interested as to where I could get a copy of their survey. I'm looking in on the internet behavior here. Where do you think could I get a copy for the Nielsen Survey? Many thanks! Hi Yuga!

I have a curious question I thought you might know the answer to. If you were asked to figure out how many people in a city are using the internet, what would be your minimum sample size for say 1 million population like CDO? Would a sample size of 100 do? Can you do it with less or you'd need more (keep margin of error at +/-5%)? Thanks for the clarification, Reg.

Re: CDO, we really have to look at the sampling algorithm used by Nielsen for this research. There are different ways on how they got the sample (I'm assuming they had a variation of a randomized sampling method.) If 20++ was the number they got, then that's the algorithm's call. As sample sizes go, I guess the number was adopted because it works in theory (i.e. Central Limit Theorem, and all that statistical stuff). How it actually mirrors the real situation in the Philippines is a different story. :) Hi Abe!

Given that this research was only done in urban areas, the numbers holds true to only 48% of the country. The other 52% were not included. My guesstimate is that for the 52% (rural) of the population, the numbers are very much skewed towards the lower end of the bracket. That means the 28% internet user of the 48% of the population added to the 1% (my number) internet users of the 52% of the population gives us a theoretical ~15% of the total population. When I saw the numbers reported in the news, the percentage was mistaken as representative of the whole country, not the just urban areas. That basically made the numbers looked promising.

In fact, the 28% figure tells us that a lot of us do use the Internet, although not all the time. You left out some interesting tidbits, such as the 71% who access the Internet in cafes and very low e-commerce activity. Come to think of it the 5% who use the internet everyday isn’t that bad.

I have a poor grasp with numbers so I cannot make a derivation on how they arrived at that number. but if it (survey) only has +/- 3% margin of error, indeed that is a good number already. my only concern is how these respondents were chosen. I am going to assume that they did this randomly, it should be OK. my problem is, I don’t thin Yahoo! is really the top search engine that we are using. in your experience guys, do you really think it’s Yahoo! in my company, I know of no one at all who still uses Yahoo! for search. as an instant messenger, yes. at first glance, 20++ for a city like CDO is not impressive.

While more is still better when it comes to statistical significance, 1,200 is already a good number from a market research point of view-- for a population like the urban areas in the Philippines, you'd need around somewhere around 1,100 to have a 95% confidence level for the data results.
