I have my science ISA paper 2 and the first question is about quantitative relationships. It is an experiment and there are results. I know quantitative data means number data but what is quantitative relationship between variables (changes)

Quantitative relationships refer to the mathematical connections between different variables or quantities. They involve understanding how one variable changes in relation to another, often described through equations, formulas, or graphs. By analyzing these relationships, we can make predictions or draw conclusions about how changes in one variable may affect another.

∙ 11y agoBy nature science is a quantitative discipline, that is a science law has always to be configured as a relation between measures of determined quantities. A good example of science law is the Ohm law:
V= R I
this law means that is two points in an electrical circuits are considered and the current and potential drop are measured between these two points, they are proportional (at least within the validity limits of the Ohm law) and the proportionality coefficient is the resistance between the two points.
Nevertheless, sometimes during experimentation it becomes clear that there is a relationship between certain quantities, but the nature of such a relationship is not clear.
For example, experimenting with electrical circuit I could observe that increasing the potential difference V the current I always increases, without being able to obtain a precise law starting from available data: this is a qualitative law. This can be a precious intermediate result, guiding on the way of finding a quantitative relation, nevertheless it is always an intermediate result.

Which branch of chemistry deals with mass relationships among reactants and products in chemical reactions?
Stoichiometry is the branch of chemistry that deals with the quantitative relationships between reactants and products in chemical reactions. It involves calculations based on the principles of conservation of mass and the mole concept.
Is reverse-transcription polymerase chain reaction quantitative or qualitative?
Certainly rt-PCR is qualitative and can also theoretically be quantitative. Anneal the RNA to get a 1:1 RNA to DNA copy, then proceed with quantitative PCR.
What is aftificial separation?
that it not alwasys quantitative.
Is age of a person quantitative data?
Yes, age is quantitative data because it is a numerical measurement that represents a person's age in years.
Are odorless and colorless are quantitative terms?
No, odorless and colorless are qualitative terms that describe the properties of substances. Quantitative terms are used to describe measurable quantities, such as temperature or volume.
Quantitative research is often reported as what to aid understanding?
Quantitative research are methodologies and reporting of numerical values, statistics and relationships to describe and model phenomena. Quantitative and qualitative procedures serve as the aid and foundation to understanding and executing the scientific method.
Which sociological research method is most likely to produce quantitative data that will identify cause and effect relationships?
Experimental research methods are most likely to produce quantitative data that can identify cause and effect relationships in sociology. This involves manipulating variables and observing the effects on outcomes.

Which sociological research method is most likely to produce quantitative data that will identify cause-and-effect relationships?
Experimental research method is most likely to produce quantitative data that will identify cause-and-effect relationships in sociology. This method involves manipulating an independent variable to observe the effect on a dependent variable, allowing researchers to establish causal relationships between variables.
Which sociological research method is most likelyto produce quantitative data that will cause and effect relationships?
Experimental research method is most likely to produce quantitative data that shows cause-and-effect relationships within sociology. This method involves manipulating one or more variables to observe their effect on another variable in a controlled environment, allowing researchers to establish causal relationships with greater certainty.
What are the advantages of quantitative techniques?
Quantitative techniques allow for data-driven decision-making, providing objective and measurable results. They can help identify trends, patterns, and relationships in data that may not be obvious through qualitative analysis alone. Additionally, quantitative techniques can be used to make predictions and forecasts based on statistical models.
Were aristotle's predictions of heavenly motion quantitative or qualitative?
Aristotle's predictions of heavenly motion were qualitative rather than quantitative. He described the motion of celestial bodies in terms of their natural behavior and relationships rather than using mathematical equations or measurements.
What are the difference about quantitative and quantitative?
Nothing, quantitative and quantitative are the same thing....
Definition of quantitative science?
Quantitative science refers to the study of natural or social phenomena through the use of quantitative data and mathematical models. It involves the collection, analysis, and interpretation of numerical data to understand patterns, relationships, and trends. This approach allows for precise measurements and predictions based on statistical and mathematical analysis.
What are the Types of qualitative and quantitative research?
Qualitative research includes methods like interviews, focus groups, and observations that aim to explore experiences and opinions. Quantitative research involves numerical data collection and analysis, using methods such as surveys and experiments to measure relationships and patterns.
Is the students age qualitative or quantitative?
It is quantitative.
What is stoichimetry?
Stoichiometry is the branch of chemistry that deals with the quantitative relationships between reactants and products in chemical reactions. It allows us to determine the amount of each substance involved in a reaction, based on the balanced chemical equation. By using stoichiometric calculations, chemists can predict how much of a product will be formed or how much reactant is needed.
