What type of sampling is it when you are taking the first 100 numbers..please help.?
Answers:
It sounds like random sampling. why?
I am not sure what you mean, if it were simply, say, the first 100 names in the Manchester telephone system's number data base, then it would not be random because only a relatively few people whose last name began with an A would be included.
Now, if all those numbers were mixed up in a hat, and the first 100 drawn were to be used, then the sample is random because anyone in the number data base could theoretically been chosen.
Let's have a little fun with this.
It is impossible to sample, say all 110,000 chocolate bars made by a company in one month. However, quaity control wants to make sure each has a certain number of nuts in them
So as the bars are completed at end of the assembly line, once a week, a quality control person randomly grabs 100 bars and counts the nuts in it. Again, any of the 110,000 could have been chosen, but the person merely grabs 100 of them.
Through inferential statistics the company can estimate with high accuracy if all the candy bars produced have the right amount of nuts by merely counting nuts in 100 bars. The key: ALL bars had an equal chance of being selected; this is what made the sampling random.
need just a little more info..it does sound like random samplin though..if it's anythin 2 do with population.ask in the biology/ecology section...they do alot of samplin.good luck.x
From the info that you have given, it would be opportunity sampling, as you are choosing the first 100 objects that you can find.
The size of the sample has nothing to do with the type of sampling in use. You misunderstood the question.
