How many simple random samples of size 3 can be selected from a population of size 7?
7*6*5/(3*2*1) = 35
When individuals all have an equal chance of being selected and all samples have an equal chance of being selected its called a stratified random example convenience cluster or simple random sample?
Simple random sampling.
What sample selected in such a way that each member of the population has an equal probability of being included?
It is a simple random sample.
Randomization in an experiment means that the experimental units or subjects are selected as a simple random sample from the whole population under study?
False
Example of stratified random sampling?
In stratified sampling, the population to be sampled is divided into groups (strata), and then a simple random sample from each strata is selected. For example, a state could be separated into counties, a school could be separated into grades. These would be the 'strata'.
How many simple random samples of size 5 can be selected from a population of size 35?
There are 324,632 possible samples.
How many simple random samples of size 3 can be selected from a population of size 7?
7*6*5/(3*2*1) = 35

Simple random sampling.
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.
When you draw a sample from a normal distribution what can you conclude about the sample distribution?
The answer depends on how the sample is selected. If it is a simple random sample, of size n, then it is distributed approximately normally with the same mean as the population mean.The answer depends on how the sample is selected. If it is a simple random sample, of size n, then it is distributed approximately normally with the same mean as the population mean.The answer depends on how the sample is selected.

How many simple random samples are possible of size 40 from a population of size 500?
Approximately 1.364*1060
What sample selected in such a way that each member of the population has an equal probability of being included?
It is a simple random sample.
When every Member of a population has the chance of being selected based on probability what type of sampling is this?
Simple random sampling.
What is the formula for simple random sampling?
The formula for simple random sampling is: n = N * (X / M) Where: n = number of samples N = population size X = sample size chosen M = total number of units in the population
What is stratified random sampling in statistics?
Stratified Random Sampling: obtained by separating the population into mutually exclusive (only belong to one set) sets, or stratas, and then drawing simple random samples (a sample selected in a way that every possible sample with the same number of observation is equally likely to be chosen) from each stratum.
How can data be collected if independent samples are to be obtained?
Data can be collected for independent samples by randomly selecting individual units or cases from the population of interest. This can be done using random sampling techniques such as simple random sampling, stratified sampling, or cluster sampling. By ensuring that each sample is selected independently of the others, we can maintain the assumption of independence among the samples in the data analysis.
At a large University a simple random sample of 5 female professors is selected and a simple random sample of 10 male professors is selected The two samples are combined to give an overall sample of?
Oh, what a happy little accident! When you combine those two samples of female and male professors, you create a beautiful overall sample that represents the diversity of the university. Each professor's unique perspective and expertise will contribute to a richer understanding of the academic community. Just like mixing different colors on your palette, blending these samples together can create something truly special.
