∙ 14y agoVarying the sample size can detect systematic errors related to sampling bias or outliers. With larger sample sizes, trends and patterns in the data become more apparent, making it easier to identify any biases in the sampling process or extreme values that may skew results. This can help researchers understand and correct for these systematic errors to improve the reliability and validity of their findings.
Stratified random sampling.
The results of the study were skewed because of the small sample size used in the research.
When a sample is aspirated into the flame in atomic absorption spectroscopy, the solvent evaporates, leaving the atoms in the sample in a gaseous state. These atoms are then heated in the flame, causing them to reach an excited state. As they return to their ground state, they emit light at characteristic wavelengths that are detected by the instrument to determine the concentration of the element in the sample.
The sources of flame photometer errors include variations in flame temperature, sample aspiration rate, and flame stability. Other sources can include interferences from other elements in the sample, improper instrument calibration, or sample contamination. Regular maintenance and calibration can help minimize these errors.
A test tube (or sample tube) has no errors.

A systematic sample is not something that you can solve!
... should be increased by a factor of 4. Note that this implies that the only errors are statistical (random) in nature; increasing the sample size won't improve systematic errors.
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.
Stratified random sampling.
That is not true. It is true for a simple random sample but not one that is systematic.

When the sample - whether it is random or systematic - is somehow representative of the population.
Common errors in measuring accuracy of an object include human error, instrumental error, environmental factors, and systematic errors from calibration issues. Additionally, inconsistent measurement techniques and insufficient sample size can also lead to inaccuracies in measuring accuracy.

An unwanted influence on a sample refers to any factor that can introduce bias or error into the sample, potentially affecting the accuracy and reliability of the results. This could include environmental factors, human error, contamination, or systematic errors in measurement techniques. Minimizing unwanted influences is critical in ensuring the validity of study findings.
