How does sample size affect the validity of an experiment?
The sample size has no effect on the validity of an experiment: instead, it is the experimental procedure and integrity of the experimenters.The sample size can affect conclusions that may be drawn from an experiment. The larger the sample is, the more reliable these conclusions are.
What is meant by population?
The full set of data from which a subset (sample) is taken.
What the union was fighting for at the beginning of the war?
The integrity of the USA - which largely meant safeguarding the cotton revenues.
Calcium is bound by what tube additive?
Calcium is bound by the tube additive ethylenediaminetetraacetic acid (EDTA) during sample collection to prevent coagulation and preserve the integrity of the sample for testing.
Why is boric acid inside a urine sample bottle?
Boric acid is used as a preservative in urine sample bottles to prevent the growth of bacteria and preserve the integrity of the sample for testing. It helps to maintain the pH of the urine and keep it stable until it can be analyzed.
Why is it advisable to keep atmospheric moisture from getting into the sample?
Moisture in the sample can introduce contamination or alter the sample's composition, leading to inaccurate results. It can also cause degradation of the sample, resulting in the loss of important information. Keeping atmospheric moisture out helps maintain the integrity of the sample for more reliable analysis.
How can you ensure the freshness of a urine sample?
To ensure the freshness of a urine sample, it is important to collect it in a clean, sterile container as soon as possible after it is produced. It should be stored in a refrigerator or kept on ice until it can be tested. This helps prevent bacterial growth and maintain the integrity of the sample for accurate results.
What is the purpose of the rubber stopper sleeve on a multisample needle?
The rubber stopper sleeve on a multisample needle helps to prevent leakage of blood or other fluids during sample collection. It also helps to maintain sample integrity by creating a barrier between the needle and the sample, reducing the risk of contamination.
Why should you take care not to contaminate the outside of the sample container?
Contaminating the outside of the sample container can introduce external substances that may interfere with the analysis or lead to inaccurate results. It can also compromise the integrity of the sample or cause cross-contamination with other samples. Maintaining a clean exterior of the container ensures the purity and reliability of the sample being tested.
What are the benefits of using SV tube for sample collection and storage?
The benefits of using an SV tube for sample collection and storage include preserving the integrity of the sample, preventing contamination, and ensuring accurate test results. The SV tube's design helps maintain the stability of the sample and allows for easy storage and transportation. Additionally, the tube's properties help protect the sample from degradation and maintain its quality for future analysis.
What is the term for a small group that accurately reflects a large population?
The term is "representative sample." It is a subset of a population that accurately reflects the characteristics of the whole population it is meant to represent.
Why is it important to refrigerate a urine sample?
Refrigerating a urine sample helps to slow down the growth of bacteria that can cause the sample to deteriorate or become contaminated. This helps to maintain the integrity of the sample for accurate testing and analysis. Refrigeration also helps preserve the chemical composition of the urine for more reliable results.
