How would you determine the difference between a qualitative and a quantitative measurement?
A quantitative measurement tells you a number in some dimension, such as the wavelength of light of that "yellow" solution, the numerical weight of something, temperature, length, number of units in a given area or volume (ppm), etc.

What is quantitative measurement?
A quantitative measurement is one in which a particular quantity is measured. This can be as simple as measuring how long something is with a ruler or tape measure, or how heavy something is with a set of scales. This is to be distinct from a qualitative measurement in which you are only interested in the presence of absence of a particular condition. You use instrumentation to determine a quantitative measurement. You can use your 5 senses to determine qualitative measurements.
What is the main difference between qualitive and quantive observations?
The main difference between qualitative and quantitative research/observations are the purposes of the observations. Qualitative research uses a small number of cases to determine the underlying reasons and motivations of an action. Quantitative research uses a large number of cases to create a generalized result.
How do you make a qualitative experiment?
A qualitative experiment is one where you determine WHAT happens, as opposed to a quantitative experiment where you measure how much of something happens.
What is the definition of qualitative knowledge?
There are basically two kinds of observations that scientists make, which are described as qualitative and quantitative. A qualitative observation gives you a general description. For example, a particular substance might be observed to be a liquid, blue in color, in a bottle. Quantitative observation involves measurement. For the same substance you might discover that it weighs 1.098 kg, that it has a temperature of 23o C, and by pouring it into a graduated cylinder, you could determine that it has a volume of 1.3 liters, etc. Qualitative observations don't involve numbers, and quantitative observations do.
Which of the two words means study of qualitative or quantitative?
Qualitative analysis is analysis carried out to show the presence or absence of something whereas quantitative analysis is analysis carried out to determine the actual amount or concentration of something. hope this helps.
What is the difference between test and measurement?
A test is generally qualitative. That is, you are testing for the presence or absence of some particular property. A measurement is quantitative. This is when you are trying to determine the amount or extent of some quality. A measurement can be represented by some number. A test light might tell you that there is voltage across two terminals. A volt meter could give you a measurement of how much voltage there is across the terminals. For instance, 5 volts or 12 volts or 120 volts.
Geologists would used qualitative measurement to?
- to determine the chemical nature of a rock - to determine the age of a rock by comparison
Is density a qualitative and quantitative?
Density is a quantitative property of matter that describes the mass of a substance per unit volume. It is typically expressed in units such as grams per cubic centimeter.
Is acid-base titration an qualitative or quantitative?
Acid-base titration is a quantitative analytical technique used to determine the concentration of an acid or a base in a solution. By measuring the volume of titrant required to reach the equivalence point, one can calculate the concentration of the analyte in the original solution.
What is qualitative and quantitative analysis in gas chromatography?
Qualitative analysis in gas chromatography involves identifying the components present in a sample by comparing their retention times with known standards. Quantitative analysis involves determining the amount or concentration of each component in a sample using calibration curves or peak area measurements.
Which one is for measuring qualitative or quantitative?
Quantitative data is measured using numerical values, such as height or weight, while qualitative data is measured by characteristics or attributes, like color or texture. The tools and methods used to measure quantitative data are typically statistical in nature, focusing on numbers and calculations, while those used to measure qualitative data often involve observations, descriptions, or categorizations.
Is a case control study qualitative or quantitative?
A case-control study is qualitative. This is because this kind of study is an observational study, meaning that it involves observing how groups differ in their behavior. The word qualitative measures the quality of something rather than the quantity (qualitative), meaning that a qualitative study measures their data through characteristics rather than numbers.
