Quantitative computed tomography (QCT) uses X-ray images to create a 2D or 3D model of a body part, with QCT software analyzing the images to generate numerical values for bone volume, mass, and density. QCT is commonly used in bone densitometry and can distinguish between cortical and trabecular bone. Quantitative computed tomography is a form […]
Choosing the right quantitative analytics model depends on the field and questions being asked. Financial professionals might use technical analysis, market researchers assign numerical values, and computing professionals monitor automated systems. Knowing the desired outcomes is important. Outcome logic design helps make strategic decisions, while needs-based assessments interview stakeholders to determine demand. Consult with all […]
Quantitative fluorescence is a technique used in biology to study single cells and whole organisms. Samples are stained with fluorescent labels and observed through a camera to collect specific and measurable information. Precision equipment is required, and the technique is used in pathology laboratories and research. Quantitative fluorescence is the display of radiation emitted in […]
Quantitative genetics studies natural variation in observable genetic traits, such as height, influenced by both genotype and environment. Researchers analyze distribution curves of traits to understand genetic inheritance and natural variation within populations, which can aid medical diagnosis and treatment. Understanding the full natural variation of genetic traits and environmental factors can help identify unique […]
Qualitative and quantitative research are debated in the social sciences. Quantitative research collects numerical data and is less biased, while qualitative research is more subjective and produces stories and descriptions. The debate continues on which approach is better for fields such as sociology and psychology. Qualitative and quantitative research are the two main schools of […]
A quantitative hypothesis involves a null and alternative proposition, tested through statistical analysis to determine if an independent variable affects a dependent variable. It has specific limitations and is expressed in numerical terms. Results are translated into mathematical values and analyzed through statistical analysis. A quantitative hypothesis contains a null proposition and an alternative that […]
Quantitative physics involves repeated measurements and mathematical analysis of experimental results to draw conclusions from statistical analysis of large amounts of data. It uses mathematics to understand the forces at work in the universe and is important in physics because physical laws cannot be defined quantitatively by human observation alone. Computational physics complements quantitative physics […]
Quantitative mass spectrometry determines molecular mass and composition by ionizing and analyzing charged molecular fragments. It can analyze organic compounds, isotopes, and biological molecules such as proteins. Quantitative mass spectrometry is a method of determining both the molecular mass of a compound and what it is made from. Mass spectrometry works by exposing a sample […]
Quantitative data collection is important in many fields, and principles such as eliminating errors, collecting all data, and testing multiple times should be applied. Tolerable error ranges should be determined, and outliers should not be ignored. Running multiple trials and using separate groups can minimize errors. There are many different areas of scientific and practical […]
Quantitative research uses numbers for data analysis in various disciplines, including epidemiology, science, and medicine. Manual and automated data collection methods are used, with automated methods being more accurate. Quantitative research is used in clinical research studies, and the ultimate goal is to obtain results that can be analyzed statistically. Qualitative research produces values based […]
Quantitative analysis tools include graphs, linear regressions, and hypothesis testing, useful for organizing and examining data, predicting events, and determining relationships. Charts, histograms, and multiple regression analysis are also commonly used. Hypothesis testing is used to determine the likelihood of an event occurring under specific conditions. Different types of quantitative analysis tools include graphs, linear […]
Quantitative titration is a chemical analysis technique used to gather information about an unknown sample through a controlled reaction with a known sample. It is commonly taught in chemistry classes and can be used for tasks ranging from pathology to analyzing pollutants in water. The goal is to reach the equivalence point, and automation is […]
Quantitative management uses mathematical models to find solutions to workplace challenges. It involves objective and structured problem-solving, but may not be suitable for all situations. Intelligence gathering patterns can be used to develop detailed background information for analysis. A quantitative management approach involves the use of mathematical models to find the best solutions to problems. […]
Quantitative forecasting techniques analyze raw data and statistics to evaluate numerical data and trends. Simple move, weight move, exponential smoothing, and time series analysis are commonly used. The Simple Rolling Forecast Method evaluates trends over an adjustable set period, while the weight movement method dissects data over one testing period with different weights given each […]
A good quantitative methods course for graduate students should use multiple teaching methods, be relevant to their field of study, require real-life projects, and have accessible instructors. Students should choose a course with quality teaching materials and in their field of study, and ideally, one where they can carry out a research project and have […]
Quantitative image analysis uses computer technology to analyze digital images for data and information. It is used in medical fields, security, and other applications. The data is analyzed using statistical and modeling techniques, and individuals in this field have advanced degrees. Quantitative image analysis involves the use of digital images to provide data and information. […]
Quantitative feedback is measurable and provides insights into employee and company performance. It can be developed through surveys, comment cards, and supervisor and employee response sheets. A consultant can assist in building a functional feedback system. Quantitative feedback is an assessment performed based on measurable results and metrics. It provides actionable insights into employee and […]
When choosing quantitative analysis books, it is important to have a plan, find books with applicable tools, and review their validity. Textbooks and consultant-written books are common sources. Companies should select books with techniques that match their specific situation and review the formulas and authors. However, books cannot replace human analysis in business decision-making. Quantitative […]
Quantitative business analysis uses financial information and statistical models to judge a business’s strength. It can be used by investors or managers and involves assigning numerical values to criteria such as profitability and customer relationships. Financial ratios are a common tool, but inputting correct and relevant information is crucial. Context is also important, and the […]
Quantitative finance uses economics, math, and IT to predict market behaviors. Choose books based on your level of interest or expertise, and consider consulting professors or reading books aimed at the general public. Choose current books for practical application. Quantitative finance is a form of financial engineering that incorporates principles from economics, mathematics and information […]
