What is important for a scientific sample?
self selected
What is Haphazard selection?
Haphazard Selection is procedure of selecting a sample of individuals to study by taking whoever is available or happens to be first on a list.
Can you tell me one of Descriptive research title sample and its problems?
lifestyle is one of the important cause of the obesity
What is the significance of sampling in research and what are the characteristics of a good sample?
Sampling is important as data collected is used to test the hypothesis. A good sample is a true representation of the general population. In addition, it should be flexible and focus on the research objectives.
Science what is a sample taken without bias?
The answer is Random Sample
What is gross sample in analytical procedure?
A gross sample in an analytical procedure is a large, random sample that is collected from a bulk material or substance. It is representative of the entire lot and is used for further analysis and testing to ensure accurate results. Subsamples are typically taken from the gross sample for more detailed analysis in the laboratory.
What is the purpose of drying a sample in analytical chemistry?
The purpose of drying is to lower the moisture content in order to guarantee conditions favourable for storage or for further processing or handling of the product.The purpose of extraction and drying is to obtain samples that are free of hydrocarbons, water and soluble salts that are suitable for further analysis.
What are the sample problems for graphical and analytical method?
Graphical method sample problem: Find the solution to the system of equations: 2x + 3y = 12 x - y = 3 Analytical method sample problem: Solve the system of equations using substitution method: 3x + 2y = 11 4x - 5y = -7
Why is it important to follow the procedure for collecting soil sample?
It is important to follow the procedure for collecting soil samples to ensure accuracy and consistency in the results. Proper sampling techniques help to minimize variability and ensure that the data collected is representative of the site. Following the procedure also helps to maintain the integrity of the sample and prevent contamination.
Why is tissue storage important?
Tissue storage is important because it allows for long-term preservation of samples for future analysis or research. This is especially critical for biological and medical studies where samples need to be kept intact for extended periods of time. Proper tissue storage also ensures sample integrity, preventing degradation and maintaining sample quality for accurate results.
How do you know if a sample is more contaminated than other?
You can determine if a sample is more contaminated than another by comparing the levels of contaminants present in each sample. This can be done through analytical testing methods such as chemical analysis or microbiological testing. The sample with higher concentrations of contaminants is considered more contaminated than the sample with lower concentrations.
Does someone have a sample letter for instituting storage fees?
A sample of what you can write in a letter for instituting storage fees is how much will be charged. You should also disclose when these fees will go into effect. It is important to give users time to remove their items if they choose not to stay and pay these fees.
What is the branch of chemistry which study the composition of a sample?
This branch of chemistry is called analytical chemistry.
How does a light scattering detector work in the context of analytical instrumentation?
A light scattering detector in analytical instrumentation works by measuring the amount of light scattered by particles in a sample. This scattering pattern provides information about the size, shape, and concentration of the particles in the sample, helping to analyze and identify substances present in the sample.
What is the Correct procedure for handling sample of pond water?
place the sample on the microscope slide and observe it.
Why we are choosing plasma matrices in bio analytical sample preparation?
because it is the matrix in which circulating analytes reside
What is the object of sampling operation in analytical chemistry?
The purpose is to obtain a statistical representative sample from the material to be tested.
