Each item in the population has an equal chance to be chosen. Usually a computer algorithm is used to generate a set of random numbers (most spreadsheet . Then the items are chosen using the set of random numbers, either as they come off the assembly line or if they are serialized, you can just go pick those items.

What is random distribution in biology?
A random distribution is a random sample set displayed in the form of a bell curve. See random sample set.

How can you choose a random sample of teachers?
The first step is to establish a sampling frame. This is a list of all teachers in the domain that you are interested in. Next you allocate a different number to each teacher. Then you use a random number generator to generate random numbers. You select each teacher whose number is generated. If the teacher has already been selected for inclusion in the sample, you ignore the duplicate and continue until you have a sample of the required size.
HELP How does a random number generator choose a sample of people?
If the population is of size N, then you allocate the numbers 1 to N to them: one per element of the population. Then generate random numbers in the range 1 - N. The element whose number is thrown up by the generator is in the sample. In the unlikely event that a number is repeated, you ignore the repeat and continue drawing the sample until you have the required correct number in the sample.

Difference between random sample and convenience sample?

Does use of chi-square demand a random sample?
Well, sort of. The Chi-square distribution is the sampling distribution of the variance. It is derived based on a random sample. A perfect random sample is where any value in the sample has any relationship to any other value. I would say that if the Chi-square distribution is used, then every effort should be made to make the sample as random as possible. I would also say that if the Chi-square distribution is used and the sample is clearly not a random sample, then improper conclusions may be reached.
When taking a systematic random sample of size n every group of size n from the population has the same chance of being selected.?
No, that would be a random sample.
When taking a systematic random sample of size n every group of size n from the population has the same chance of being selected?
No, that would be a random sample.
What You decide you want your sample to be representative of the population. Which sampling process would provide the most representative sample?
A simple random sample.
What is the difference between simple random sampling and systematic random sampling?
simple random sample is to select the sample in random method but systematic random sample is to select the sample in particular sequence (ie 1st 11th 21st 31st etc.)• Simple random sample requires that each individual is separately selected but systematic random sample does not selected separately.• In simple random sampling, for each k, each sample of size k has equal probability of being selected as a sample but it is not so in systematic random sampling.
What is the difference between random and stratified sample in the survey method?
The main difference is that the way of selecting a sample Random sample purely on randomly selected sample,in random sample every objective has a an equal chance to get into sample but it may follow heterogeneous,to over come this problem we can use stratified Random Sample Here the difference is that random sample may follow heterogeneity and Stratified follows homogeneity
