Best–worst scaling (BWS) [1] techniques involve choice modelling (or discrete choice experiment – "DCE") and were invented by Jordan Louviere in 1987 while on the faculty at the University of Alberta. In general with BWS, survey respondents are shown a subset of items from a master list and are asked to indicate the best and worst items (or ...
The top grade, A, is given here for performance that exceeds the mean by more than 1.5 standard deviations, a B for performance between 0.5 and 1.5 standard deviations above the mean, and so on. [18] Regardless of the absolute performance of the students, the best score in the group receives a top grade and the worst score receives a failing grade.

The choice of grading system at Nigerian schools depends on the institution and sometimes on the faculty of the institution. In addition, grading scales at university-level institutions have changed frequently. Grading scales can be 1 to 8, 1 to 4, or A through G, where A is on a 4.0 scale or on a 5.0 scale.
Grades can be assigned as letters (usually A to F), as a range (for example, 1 to 6), as a percentage, or as a number out of a possible total (often out of 100). [1] In some countries, grades are averaged to create a grade point average (GPA). GPA is calculated by using the number of grade points a student earns in a given period of time. [2]
