The Gini coefficient measures wealth distribution within a country, with a higher number indicating greater inequality. It is calculated using a graph of income and population share percentages, with the area of the gap divided by total wealth. The coefficient ranges from 0.0 to 1.0, with 0.0 representing perfect distribution and 1.0 representing ultimate inequality. […]
The shading coefficient measures a glass panel’s ability to insulate against solar heat. It is affected by factors such as color, thickness, and reflectivity. A lower rating means less solar heat is transmitted. Proper measurement is important for large buildings, but some structures may desire a lower coefficient for solar heat transmission. In general, a […]
The coefficient of static friction is a numerical value that determines the force required to initiate motion between two objects. It varies with the materials they are made of and is symbolized by the Greek letter “mu”. The lower the coefficient, the more slippery the surfaces are. When the gravitational force is greater than the […]
The drag coefficient is a numerical figure that represents an object’s drag when it moves against a fluid medium. It can be calculated using the formula 2Fdd/pv2A and varies based on the speed and shape of the object. The larger the area, the higher the drag coefficient. Automobile design uses this principle to create faster […]
The ballistic coefficient of a bullet measures its resistance to drag when fired through the air. Factors such as the mass of the projectile, its shape, and air density affect its trajectory. Understanding bullet behavior is important for gun design. The shape of a projectile is designed to minimize drag, and calculations use a shape […]
The information coefficient measures the quality of stock predictions by calculating the correlation between forecast and actual prices. Analysts with higher coefficients are more valuable to employers, who can act on their predictions to make a profit. The task of financial analysts is to obtain information before others, but this can lead to illegal behavior […]
