Samples are chosen in such a way that each member of the population has a known,though not necessarily equal, chance of being included in the sample?
Random samples

Measurements from a population are called?
Samples
What is the definition of simple random sample?
There are two equivalent ways of defining a simple random sample from a larger population. One definition is that every member of the population has the same probability of being included in the sample. The second is that, if you generate all possible samples of the given size from the population, then each such sample has the same probability of being selected for use.
What is the definition for probability sample?
A probability sample is one in which each member of the population has the same probability of being included. An alternative and equivalent definition is that it is a sample such that the probability of selecting that particular sample is the same for all samples of that size which could be drawn from the population.
What is success independent samples design?
different samples of respondents from the population complete the survey over a time period
How many simple random samples of size 5 can be selected from a population of size 35?
There are 324,632 possible samples.
What is the difference between convenience judgment and random sampling?
Non-probability or Judgement Samples has to do with a basic researcher assumptions about the nature of the population, the researcher assumes that any sample would be representative to the population,the results of this type of samples can not be generalized to the population(cause it may not be representative as the research assumed) and the results may be biased. Probability or Random samples is a sample that to be drawn from the population such that each element in the population has a chance to be in the selected sample the results of the random samples can be used in Statistical inference purposes
How are biased and unbiased sample similar?
They are samples from a population, but otherwise they are not similar.
Do samples have the same characteristics of population?
If they are randomly drawn and large enough.
What is the sample size definition?
Sample size is the number of samples arawn from a population. If you drew 20 samples, your sample size would be 20.
Why are random samples more representative of the population than other kinds of samples?
A 'random' sample - covers all age groups, genders, and other criteria. A 'targeted' sample might only cover a small part of the population.
How do samplers work to capture and analyze data in a systematic manner?
Samplers work by collecting small, representative samples of data from a larger population in a systematic way. These samples are then analyzed to draw conclusions about the entire population.
What conditions are necessary in order to use a test to test the differences between two population means?
The samples must be randomly selected, independent, and normally distributed. The following are necessary to use a t-test for small independent samples. 1. The samples must be randomly selected. 2. The samples must be independent. 3. Each population must have a normal distribution.
