Analytical skills involve logical and critical thinking to derive meaning from information or construct/deconstruct an argument. They are important in many professions and begin developing early in life. Lack of analytical skill education can lead to difficulties later in life, especially for children with cognitive or learning disabilities. An analytical skill is the ability to […]
Online analytical processing (OLAP) is a data analysis technique used in business intelligence (BI) that involves using multidimensional databases for rapid reporting and trend analysis. OLAP cubes relate measures and dimensions, and OLAP databases are often smaller and faster than data warehouses. OLAP specialties include multidimensional, relational, and hybrid. BI also includes data mining, reporting, […]
The Analytical Engine, created by Charles Babbage in the mid-1830s, was a mechanical computer that used punch cards for programming and had a processing unit and short-term memory. Babbage first invented the specialized difference engine before broadening his focus to create the multipurpose analytical engine. The engine could solve equations and store up to 1,000 […]
Analytical chemistry careers range from private pharmaceutical jobs to government environmental quality oversight. Chemists test materials for composition and contamination, with jobs in public sectors, private companies, educational institutions, and non-profit organizations. A bachelor’s degree in analytical chemistry is required, with higher degrees for specialized work. Careers in analytical chemistry span a wide spectrum, from […]
Quantitative analytical chemistry measures known substances in a sample for quality control, while qualitative analytical chemistry identifies unknown substances. Organic analysis is complex and uses instrumental methods like gas-liquid chromatography and electrophoresis. Inorganic analysis applies to carbonless chemistry and uses modern instrumental methods like atomic absorption or atomic emission spectroscopy. TLC is a vital technique […]
Analytic dynamics is a branch of physics that describes the effects of forces on physical objects, using Sir Isaac Newton’s theories and calculus. Later scientists, such as Lagrange and Hamilton, generalized the behavior of physical systems with more advanced mathematics, leading to the study of field theories and quantum mechanics. Analytic dynamics uses scalar properties […]
Analytical balances use comparisons to measure weight, with modern single-pan balances commonly used for small, accurate weights. Chemistry requires high accuracy, achieved through a clear shield and enclosed parts. Calibration knobs and tare containers aid accuracy, but caution is needed to avoid errors. Electronic balances have safety alerts, and the triple beam and equal-arm balances […]
ANP is a multi-criteria decision analysis tool that uses benefits, opportunities, costs, and risks to model sub-elements of a decision. It uses ratio scale measurements and subjective data to rank alternatives in a super matrix, which is subjected to sensitivity analysis. ANP has been used in real-world scenarios, such as a Turkish construction company considering […]
Analytical phonics teaches reading by first memorizing sight words, then analyzing their phonetic structure. It differs from linguistic and synthetic phonics by starting with stories and working down to individual letters. Students analyze phonetics to recognize letter combinations and pronounce new words. Linguistic phonics focuses on sound patterns, while synthetic phonics teaches individual letter sounds […]
Analytical reasoning involves recognizing patterns in information, whether quantitative or qualitative, to draw logical conclusions. This can be applied to numerical data using formulas or statistical models, and to prose by analyzing the author’s rhetorical structure and evidence. By isolating important evidence, readers can refute or elaborate on the author’s argument. The term “analytical reasoning” […]
An analytical exposition is a persuasive text that can be written or spoken, using expert sources or personal experience as evidence. It often follows a five-paragraph structure, with an introduction, supporting evidence, and conclusion. The writer analyzes an argument to persuade the reader that the thesis is true. The conclusion reaffirms the thesis, and new […]
Auditors use analytical procedures to test financial information and ensure it meets accounting standards. These procedures include comparing information with previous periods, calculating ratios, and soliciting information from external sources. Auditors use these procedures to identify irregularities and inappropriate accounting procedures. Analytical procedures are part of the financial audit process. The auditors use these procedures […]
