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
Stratified random sampling.
It is a type of scientific study in which one seeks to find an answer to a question using predefined set of procedures. Qualitative data sampling involves collection of evidence and production of findings that were not considered previously in the study. It also explores beyond the immediate limits of the study involved.
Sampling error cannot be avoided: it is a result of the fact that the sample that you pick for a study will not exactly match the whole population. If there were no variations between the members of the population you would only need to take a sample of size 1 - a single observation would be sufficient.

No, sampling techniques differ for solid, liquid, and gas samples. For solids, techniques like grab sampling or core sampling are commonly used. Liquids can be sampled using methods like grab sampling, pump sampling, or composite sampling. Gases are typically sampled using techniques like grab sampling, passive sampling, or active sampling using pumps or sorbent tubes.

It can be but it is not simple random sampling.

Compare the efficiency of simple random sampling with systematic random sampling for estimating the population mean and give your comments.
There are many such methods: cluster sampling, stratified random sampling, simple random sampling.Their usefulness depends on the circumstances.

They include: Simple random sampling, Systematic sampling, Stratified sampling, Quota sampling, and Cluster sampling.

There are several types of random sampling, with the most common being simple random sampling, stratified sampling, cluster sampling, and systematic sampling. Simple random sampling gives each member of the population an equal chance of being selected. Stratified sampling involves dividing the population into subgroups and sampling from each subgroup. Cluster sampling selects entire groups or clusters, while systematic sampling involves selecting members at regular intervals from a randomly ordered list.
Sampling techniques in researching involves to types of sampling. The probability sampling and the non-probability sampling. Simple random is an example of probability 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.
