What is the difference between a qualitative and a quantitative assay?
In assays, or medical tests, both qualitative and quantitative tests occur. The qualitative test identifies the presence or absence of the pathogen or toxin (or other molecule) being tested for, while the quantitative test hopes to measure how much of that particular substance is in the body.
Why Benedict's qualitative test is called semi quantitative?
The Benedict's qualitative test is called semi-qualitative since it is not totally conclusive.
How qualitative and quantitative are similar?
It depends in which context your talking about, in the psychological context Quantitative data is number data such as results from a test, percentages Qualitative data is data where you take notes of what someone is saying or how they have been acting etc not involving numbers.
Is PCR assays a qualitative or quantitative test?
PCR assays can be both qualitative and quantitative, depending on the method used. Qualitative PCR, often referred to as conventional PCR, detects the presence or absence of a specific DNA sequence. In contrast, quantitative PCR (qPCR or real-time PCR) measures the amount of DNA, providing information on the quantity of the target sequence in a sample. Thus, PCR can serve both purposes based on the specific assay design.
What are the different ways of researching?
Research can be conducted through various methods, including qualitative and quantitative approaches. Qualitative research involves collecting non-numerical data, such as interviews and observations, to explore concepts and experiences. Quantitative research, on the other hand, relies on numerical data and statistical analysis to test hypotheses and identify patterns. Additionally, mixed-methods research combines both qualitative and quantitative techniques for a more comprehensive understanding of a research question.

Is a flame test a qualitative or quantitative test?
The flame test in analytical chemistry is only qualitative.
What is the difference between quantitative and qualitative observations?
Qualitative refers to what a sample is, while quantitative refers to how much of that material is present. For example, the "squeaky pop test," which involves taking a burning splint and immersing it in a test tube, is a qualitative test. If the gas in the test tube pops, you know you have hydrogen production. In this case, no numbers are being taken - it is only to identify the gas in the test tube. Say you capture the gas released by whatever reaction takes place in the test tube. Measuring the volume of the gas would be the quantitative observation.
Why Benedict's qualitative test is called semi quantitative?
The Benedict's qualitative test is called semi-qualitative since it is not totally conclusive.
Is Heller's test qualitative or quantitative?
Heller's test is a qualitative test. It is used to detect the presence of blood in the stool, typically caused by gastrointestinal bleeding. The test involves observing a color change in the stool sample when it comes into contact with certain reagents.
What laboratory test has numeric result?
I think you're looking for the phrase "quantitative test." It gives a number. A qualitative test gives a yes/no answer. For instance, you can get a qualitative pregnancy test (yes pregnant, no not pregnant). You can also get a quantitative pregnancy test that gives you hormone levels (e.g. HCG level 985).
Is a flame test qualitative or a quantitative analysis?
A flame test is a qualitative analysis technique used to identify the presence of specific elements based on the color of the flame produced. It is not typically used for quantifying the amount of the element present in a sample.
How much does a quantitative blood test cost?
You have to be more specific. Every lab test is either qualitative or quantitative. What is the test specifically for?
How qualitative and quantitative are similar?

Is the flame test a qualitative or quantitative test for the identity of an unknown?
just looking at the color of the flame --- qualitative
Why is Benedicts test considered to be a semi-quantitative test rather than quantitative test?
Benedict's test is considered semi-quantitative because it gives a general idea of the amount of reducing sugar present based on color changes, but it is not precise enough to give an exact concentration of sugar present. The test relies on color changes to estimate the relative amount of reducing sugar, making it qualitative and semi-quantitative rather than fully quantitative.
What is the difference between quantitive and qualitive?
quantitative refers to "quantity" and can be quantified or measured. while qualitative referes to "quality" and cannot be quanitifed. When u say X product "passes" a test that is qualitative data, while when u say the amount of X present is "10mg/ml" that is quantitative data.
