There's a difference between statistic that's gathered from recording height and weight amongst 10 year olds, and an experiment where people are trialling a drug. The first is observational, the second is manipulation by the person gathering the information.
And if you know anything about statistics, you should know that a census type sample size is always going to be impossible and that a smaller sample size can be representative of a larger population as long as certain criteria stay consistent (such as all people who take the test are at university and then the results are only representative for uni students). For example The stats department asks all their student to take a test during tutorial time, one person goes out of the class at a time, fills the form in, then another person does it. I believe some other departments do the same test. There's more stuff they do to ensure it's a representative sample but to be honest it was 2 years ago now and I forget.
Your first statement is indeed correct, but that's the only one.
Statistics are experiments, they are testing a hypothesis (I think 50% of people surveyed are virgins) and you make observations and come up with a conclusion. An experiment where people trial a drug, well I have a hypothesis (50% of men who take viagra don't have an increase in erection length), I then make observations and come up with a conclusion. Wow, the same isn't it, this is where I say "Derka derka."
And if you knew anything about science, you'd know that no smaller sample size can be representative or a replacement for anything. I say 5/10 people are virgins, but we tested 100, and saw that 36 are... tested 1000 and 340 were, 10000 and 5000 were. Stats vary with every experiment, which is why you can't say "I dun readed an experiment by my professors and dey dun said dat 50% of college kids are virgins" unless you give the parameters of the experiment to understand the flaws and the fluctuation the outcome will have.
You also said that it was a completely anonymous sample, yet they TARGETED only students of stats department.
To be honest, I find it sad that people don't understand that there is more to life that having sex.
Maybe I'm taking you a bit too literally but still. I don't regret anything. I wouldn't change anything.
To be honest, I find it sad you're so stubborn. It's not a matter of understanding, because it's not fact, it's opinion. If life is sex to people, than let them hold that belief.
Kitsune has no penis, so I'm sure that wouldn't be a problem.
