Each question may contain from zero to three subsets of questions with marks ranging from 2 to 8 marks. The total weighting of the paper is 80 marks and constitutes 44% of the grade. Paper 2 (Duration: 2 hours 30 minutes): Questions are categorised into 3 sections: A, B and C. Section A contains 7 questions which must all be answered. Section B ...
All superlative indices produce similar results and are generally the favored formulas for calculating price indices. [14] A superlative index is defined technically as "an index that is exact for a flexible functional form that can provide a second-order approximation to other twice-differentiable functions around the same point."
However the exam papers of the GCSE sometimes had a choice of questions, designed for the more able and the less able candidates. When introduced the GCSEs were graded from A to G, with a C being set as roughly equivalent to an O-Level Grade C or a CSE Grade 1 and thus achievable by roughly the top 25% of each cohort.
The website was founded in 2015 by Leon Hady, a former UK headteacher. Tuitionkit started as a self-funded venture allowing students to view interactive video content to support revision in Maths, English and Science for GCSE and A Levels. As of November 2016 it has 20,000 users. [6] [7] [8] [5]
Some indices display market variations. [definition needed] For example, the Economist provides a Big Mac Index that expresses the adjusted cost of a globally ubiquitous Big Mac as a percentage over or under the cost of a Big Mac in the U.S. in USD. [4] Such indices can be used to help forecast currency values. [citation needed]
The content spans mainly across the secondary school public exams syllabus in the UK and USA such as GCSE, A Level and the SAT. [1] As of January 2015 the app has been installed over 500,000 times. Gojimo was founded by serial entrepreneur George Burgess. [ 2 ]
It is common convention to use greek indices when writing expressions involving tensors in Minkowski space, while Latin indices are reserved for Euclidean space. Well-formulated expressions are constrained by the rules of Einstein summation : any index may appear at most twice and furthermore a raised index must contract with a lowered index.
Sample of a well maintained data [clarification needed]. In statistics and research design, an index is a composite statistic – a measure of changes in a representative group of individual data points, or in other words, a compound measure that aggregates multiple indicators.
