What is anopther name for systematic sample?
Stratified random sampling.
What is a sentence with skewed in it?
Due to systematic error, my results are skewed.
What happen when a sample is aspirated into the flame?
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.
What are the sources of flame photometer?
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.
What is the source of error when using a test tube?
A test tube (or sample tube) has no errors.
How are systematic errors detected?
independent analysis blank determinations variation in sample size
How do you solve a systematic sample?
A systematic sample is not something that you can solve!
To cut the maximum likely error in half the sample size should be?
... 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.
What is the difference between simple random sampling and systematic random 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.
What is anopther name for systematic sample?
Stratified random sampling.
What kind of virus is detected by a stool sample?
rotavirus
When taking a systematic random sample of size and n every group of size n from the population has the same chance of being selected?
That is not true. It is true for a simple random sample but not one that is systematic.
When can statistics be used to gain information about a population from a sample?
When the sample - whether it is random or systematic - is somehow representative of the population.
How is Fragile X syndrome detected?
By a DNA blood sample
What are the errors committed in measuring accuracy of an object?
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.
What is an unwanted influence on a sample?
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.
Can use of inhalants be detected in a hair sample?
yes. for about 5 to 6 months.
