What is Statistics?
Statistics is a branch of Mathematics dealing with the collection, organisation ,representation and interpretation of data.
This course deals with the graphical representation of data, measures of Central tendency: Mean ,Median and Mode and Measures of Dispersion : Mean Deviation and Standard Deviation.
Statistical data can be easily understood if we represent it in the form of diagrams and graphs. Here, we study the following types of graphs: Pie Charts, Bar graphs, Histograms, Frequency Polygons.You will learn how to draw these graphs and interpret them. These form an integral part of quantitative aptitude tests.
Statistical data has the tendency to cluster around a central value. This is called Central tendency. The different ways of measuring Central tendency are Mean, Median and Mode. You will learn how to calculate these for grouped and ungrouped data,
You are introduced to Quartiles and how to calculate them using the formula.
In order to interpret the data, you should know how data is spread around a central value.This leads to measures of dispersion, namely mean deviation and standard deviation.
You will learn about Mean Deviation about the mean and mean deviation about the median for discrete and continuous frequency distributions.You move on to learning variance and standard deviation. Three methods of calculating the standard deviation are discussed.
