How to reduce sampling error?
The only way to get rid of sampling error is to use the entire population under study. This is usually impossible, so the next best thing is to use large samples and good sampling methods.
Different types of random and non random sampling?
stratified sampling, in which the population is divided into classes, and random samples are taken from each class;cluster sampling, in which a unit of the sample is a group such as a household; andsystematic sampling, which refers to samples chosen by any system other than random selection.
Is sampling distribution more compact when is is based on smaller samples?
No: the opposite.
What is a sampling variability?
A sampling variability is the tendency of the same statistic computed from a number of random samples drawn from the same population to differ.
Is questionnaire probability sampling technique?
A questionnaire has little to do with sampling technique. Sampling technique is to do with who gets the questionnaire and that can be any sampling technique: the questionnaire can be sent to everyone (census), to a random sample, stratified random samples, to random samples in clusters, by quota or convenience. Or a pile of questionnaires can be left for respondents to pick up - self-selection.
What type of sampling produces representative samples?
random sampling

What is non-probability sampling?
Non probability sampling is where the samples are not selected randomly.
How do you spell samples?
That is the correct spelling of "sampling" (taking a sample).
What is techno sampling?
Testing samples of techno.
Example of multistage sampling?
the combinitoin of any random samples is called multistage samplinag. it is the expensive form of cluster samling. when each elements in cluster are expensive then we use multistage sampling.
What is sampling and holding time?
sampling time is the number of samples per second taken from a continuous signal to make it discrete and holding time is the time between two samples..
Different types of random and non random sampling?
stratified sampling, in which the population is divided into classes, and random samples are taken from each class;cluster sampling, in which a unit of the sample is a group such as a household; andsystematic sampling, which refers to samples chosen by any system other than random selection.
Example of panel sampling?
A good example to panel sampling will be sampling the performance of a group of companies in a specified region. This way they the samples can be revisited at a later stage thus panel sampling.
Is sampling distribution more compact when is is based on smaller samples?
No: the opposite.
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.
What is a sampling distribution?
The sampling distribution for a statistic is the distribution of the statistic across all possible samples of that specific size which can be drawn from the population.
