The Online Business Dictionary define statistics as a branch of mathematics concerned with collection, classification, analysis, and interpretation of numerical facts, for drawing inferences on the basis of their quantifiable likelihood.

Statistics can be necessary when - there is need to understand and describe an occurring phenomenon, when there is need to present complicated data in a suitable tabular, diagrammatic and graphic form for easy and clear understanding of the data. Statistics are also important when we need to understand the nature and pattern of variability of a phenomenon through quantitative observations is necessary, and when we need to draw valid inferences, along with a measure of their reliability about the population parameters from the sample data is needed.

Statistics can be applied to any discipline but it is commonly used in the fields of – mathematics, business, economics, administration, banking, accounting and finance, natural and social sciences.

There are two types of statistics

  • Differential – forms the first stage of data analysis and is concern with the presentation and collection of data.
  • Inferential –this is the second stage of data analysis and is about  drawing credible  conclusions from the statistical analysis that has been collected through descriptive statistics.

The key to getting a true picture of a situation or phenomenon through statistics is ensuring that one is not biased when conducting research. This year’s theme for World Statistics Day is “Better Data, Better Lives”. All our lives rely on better statistics. For the government to provide good services to its citizen, she must understand the demography of the country. This can happen if she is equipped with necessary statistics concerning the people. Good statistics can only be achieved when data is collected in an appropriate manner. Let’s celebrate this day and encourage  people to provide statistics when required.
