Some theories that focus on qualitative change rather than quantitative change include Piaget's theory of cognitive development, Vygotsky's sociocultural theory, and Erikson's psychosocial development theory. These theories emphasize how individuals go through specific stages or phases where they exhibit distinct qualitative changes in their thinking, behavior, and understanding of the world.
The pathognomonic-intervention continuum proposed by Jordan and Stanovich is a theoretical framework rather than a specific study. It outlines the spectrum of diagnostic decisions clinicians make, ranging from clear-cut (pathognomonic) to more uncertain (intervention) cases. This framework is qualitative in nature, focusing on the nature of diagnostic reasoning rather than quantitative data collection or analysis.
Question: What is the difference between qualitative and quantitative observations and methods and what are some examples of each? Answer: From Wikipedia for QUALITATIVE Qualitative research is one of the two major approaches to research methodology in social sciences. Qualitative research involves an indepth understanding of human behaviour and the reasons that govern human behaviour. Unlike quantitative research, qualitative research relies on reasons behind various aspects of behaviour. Simply put, it investigates the why and how of decision making, as compared to what, where, and when of quantitative research. Hence, the need is for smaller but focused samples rather than large random samples, which qualitative research categorizes data into patterns as the primary basis for organizing and reporting results. From Wikipedia for QUANTITATIVE Quantitative research is the systematic scientific investigation of quantitative properties and phenomena and their relationships. Quantitative research is widely used in both the natural and social sciences, from physics and biology to sociology and journalism. It is also used as a way to research different aspects of education. The objective of quantitative research is to develop and employ mathematical models, theories and hypotheses pertaining to natural phenomena. The process of measurement is central to quantitative research because it provides the fundamental connection between empirical observation and mathematical expression of quantitative relationships. The term quantitative research is most often used in the social sciences in contrast to qualitative research. Examples of qualitative statements/observations: The freezing point of water is colder than the boiling point. The sun is very bright. A liter of water is heavier than a liter of ethanol. Examples of quantitative statements/observations: The freezing point of water is 0 °C and the boiling point is 100 °C. The sun's intensity on earth is 100 W m-2. A liter of water weighs 1000 grams and a liter of ethanol weighs 789 grams. Above retrieved from Answers.com
Qualitative observations are those that provide a sense of observed parameters or changes without reference to numerical or statistical values. Example : "A heated filament glows." "The chemical turns red." "One rod is longer." This is opposed to quantitative observations, such as "the object is moving at 4 meters per sec", "all volumes doubled in size", or "the pressure was increased to 3 atmospheres".
Qualitative education refers to an educational approach that focuses on developing students' critical thinking, problem-solving skills, creativity, and general understanding of concepts rather than just memorizing facts. It emphasizes the quality of learning experience and outcomes over quantitative measures like test scores. This approach aims to cultivate well-rounded individuals who can think independently and apply their knowledge in various contexts.
The word that means concerned with theories rather than their practical application is "theoretical."
This procedure is qualitative because it focuses on gathering descriptive data and understanding the quality or characteristics of a phenomenon rather than measuring it numerically. Quantitative procedures involve collecting numerical data for statistical analysis.
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.
Social Security numbers are quantitative and not qualitative. This is due to the fact that they are numerical in nature.
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.
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.
A qualitative property is one that defines something based on characteristics such as color or density. It refers to the description of a substance rather than a measurement of that substance. A quantitative property deals measurements of a given substance and can be expressed as a number or quantity.
Favorite color is qualitative data because it represents a characteristic or quality, rather than a numerical value. It cannot be measured or quantified in a numerical sense.
Hair color is qualitative because it is a descriptive attribute that can be categorized into different groups such as blonde, brown, or black, rather than being measured on a numerical scale.
A hot flame is a qualitative measurement, as it describes the subjective perception of the flame's temperature based on sensory experience rather than a precise numerical value.

Qualitative data refers to the qualities rather than quantities. Qualitative data may be information relative to size, shape, age, color - descriptive information. Quantitative data refers the the quantity - number of, percentage, average, amount, frequency.
