Pie charts can be drawn easily, if we remember the crucial fact that there are 360 degrees about the centre of the circle. We split this up to show the different quantities.

In many critical areas of national statistical system performance, at present there is no available data to construct measures. Of the framework’s 22 dimensions, 14 have established methods and ...

To draw a pie chart, we need to represent each part of the data as a proportion of 360, because there are \(360^{\circ}\) in a circle. For example, if 55 out of 270 vehicles are vans, we will ...

This involves the analysis of large masses of data by statistical methods, in the process of which, solutions to many complex problems have to be sought. Stimulus is thus given to purely ...

What is the goal of the new Statistical Performance Indicators (SPI)? The Statistical Performance Indicators measure the capacity and maturity of national statistical systems by assessing the use of ...

Statistical physics is a branch of physics that uses probability theory and statistics to solve physical problems that usually involve systems composed of a large number of units. Its main purpose ...
