A generalized logistic curve can model the "S-shaped" behaviour (abbreviated S-curve) of growth of some population P

bell curve is literally‚ the symmetrical curve created on a graph when using a frequency distribution method for a set of data‚ splitting the mean symmetrically. There is a big difference between standard deviation and the bell curve! Standard deviation shows the difference in variation from the average; the bell curve‚ also normal distribution or Gaussian distribution‚ shows the standard deviation and is created by the normal or equal distribution of the mean among either half. The bell curve is an

The Fry Graph Readability Formula Edward Fry developed one of the more popular Reading Formulas – the Fry Graph Readability Formula. Fry‚ who worked as a Fulbright Scholar in Uganda‚ also helped teachers to teach English as a Second Language (ESL) for a few years‚ from 1963 and onwards. During his early days‚ Fry developed readability tests based on graph [A Readability Formula That Saves Time‚ Journal of Reading (1968)]. This graph-based test determined readability through high school; it was validated

The first major change to radio was when television was introduced because before television‚ radio was one of the major forms of entertainment besides reading. So when television took over the large entertainment market‚ radio stuck to

Spectrophotometer; the finding of protein concentration of an unknown sample of BSA‚ and by using the standard curve. Abstract A spectrophotometer’s purpose is to use colors of the light spectrum to determine the concentration of light absorbing molecules in a solution. (p.59) In this particular lab‚ our mission was to determine the protein concentration and the standard curve of the unknown sample of BSA. This‚ by preparing five dilutions of the unknown solution of BSA together with other

Demand and supply The term demand refers to the quantity of a given product that consumers will be willing and able to buy at a given price. As a general common sense rule - ’the higher the price of a particular product the lower will be the demand for it ’. The term supply refers to the quantity of a particular product that suppliers (producers and/or sellers) will make available to the market at a particular price. The higher the price‚ the greater the quantity that suppliers will be willing
