What are numerical skills?
Eployee is called to resolve problems which require practical calculations, to find the analogies between numerical data.
This skill reflects the person's general intelligence and its development ensures at a great extent the attainment of organizational goals.
The evaluation of a person's numerical skills should become an essential part of both the recruitment and assessment procedures of all modern companies.
What are numerical skills?
Numerical skills refer to the way a person perceives, processes and calculates numbers and numerical symbols. According to the dominant scientific explanatory models, numerical skills are considered to comprise of a series of dimensions. These dimensions constitute this test's theoretical background. More specifically, with the use of this test a company can evaluate the following:
a) the contestant's numerical perception, that is, the extent to which a contestant can understand the meaning of numbers and of what they represent within several different contexts, such as when they are on a table, a bank account, a bill, a credit card, etc.
b) the contestant's numerical control, that is, the contestant's ability to make out more obvious and less obvious mistakes within tables of numbers and replace them with the correct prices, accordingly to the rest of the numerical data on the table.
c) the contestant's ability of rapid calculations and numerical processing, that is, the extent to which a person can make addition and subtraction, multiplications and divisions either intellectually or on a piece of paper. The use of calculators is not allowed while taking this test.
d) the contestant's ability to estimate a sum or a quantity. It refers to the extent to which the contestant is able to calculate prices approximately, according to the available data, when a precise mathematical calculation is difficult and requires a lot of time.
e) the ability of anagoge to the unit, which refers to the extent to which the contestant may define the exact numerical size/price of the smallest possible unit of a great total amount.
f) the contestant's ability to apply the simple mathematical "method of three", which refers to the ability to calculate the exact size of a fourth price, when having four numbers, three of which are known.
g) the ability to calculate percentages and dividends, that is, the extent to which the contestant may perceive the fact that a sum can be divided into pieces using percentages.
h) the speed of numerical perception, which refers to the degree to which the contestant can approach mathematical problems and meanings rapidly when certain time limitations exist.
i) the contestant's practical mathematical logic, that is, the extent to which the person has the ability to solve practical mathematical problems, without the help of equations and mathematical types or of a methodical and organized solution, but through his/her own intrinsic questioning and instinctive inspiration.
