The answer will depend on the underlying distribution for the variable. You may not simply assume that the distribution is normal.
The mean of the sampling distribution is the population mean.
It is the sampling distribution of that variable.
In statistics, a quartile is each of four equal groups into which a population can be divided according to the distribution of values of a particular variable.
The sum of proportions computed from a frequency distribution must equal

You calculate the standard error using the data.
Sampling has multiple meanings depending on the domain of work:Statistics - Sampling is selecting a subset of population from within the population to estimate the characteristics of the whole population.There are two different types of Sampling Procedure;1. Probability2. Non ProbabilityProbability sampling methods ensures that there is an equal possibility for each individual in a population to get selected.Non Probability method targets specific individuals.
The most commonly used sampling method is simple random sampling, where every individual in the population has an equal chance of being selected for the sample. It is preferred for its simplicity and unbiased nature in representing the population.
Sampling involves selecting a subset of individuals or items from a larger population for study. Random sampling is a specific type of sampling method where each individual or item in the population has an equal chance of being selected. In random sampling, the selection of individuals is done purely by chance, reducing bias in the sample.
Stratified sampling is a type of sampling that uses a fair representation of the population by dividing the population into different subgroups or strata and then selecting samples from each stratum in proportion to their size in the population. This method helps ensure that all groups in the population are adequately represented in the final sample.
The best way to reduce sampling error is to use random sampling in the study. This means selecting the population to study through a random process. This will ensure that each member of the population under study has an equal chance of being selected.
Researchers are using a procedure known as simple random sampling. This involves selecting individuals at random, where every individual has an equal chance of being selected, to ensure the sample is representative of the population.
A random sampling technique, such as simple random sampling or stratified random sampling, would be appropriate for surveying 120,000 people to ensure each person in the population has an equal chance of being selected. These techniques help reduce bias and ensure the sample is representative of the population as a whole.
Nothing, really. You may be able to say more if you knew what the underlying distribution was.
