Jagsstat-Blog Statistics -An Introduction to Statistics

  1.1. Data and Statistics Data are information collected in various form. Singular form of data is called datum. It is like natural raw resources but unlike many natural resources, data shouldn’t be preserved only but also utilized at the same time. If they are not analyzed within a stipulated time than their validity may expire and they might not be as useful. This analysis is done with proper usage of various statistical tools. Without statistics, data are just information lying around and without data, statistical tools are of no use. In other words, it can be stated that both data and statistics are interdependent, together they can be used to see future like a fortune teller and throw lights on the missing past. It helps us to detect problems and find their solution like a doctor. If statistics is the fortune teller than data is the magical spell. If data is the fuel, then statistics is the engine. ‘Data are basically information in form of text, numbers, audio, video, p...

  As fascinating as numbers are to some people, they appear as nightmares to many . Before a mathematics or statistics exam or before presenting something with statistical analysis we often become anxious which makes it all messed up for us, messing all our hard work and preparations. But are numbers really that scary? Is statistics that scary? Or is statistics just scary numbers? Let me tell you what, statistics is not just numbers but ‘story telling numbers.’ This is the magical power that statistics possess.

As over overexaggerated those stories are they are something we remem...

Have you ever questioned this when you see all this craze about data scientist, data analyst, statistical analyst etc.?

It is like that mom's touches of perfection in all your initial creation or like the sun ray silently making the moon bright. Hidden and very important. Anyways, we shall discuss that another time.  But today we shall discuss why each one of us needs to know the basic statistics.

Every one of us is born with some innate talent, knowledge and instinct. And some are acquired. Statistics can be called an instinct of our subconscious mind which guides us and helps us to make decisions in our conscious state. An instinct is an innate or acquired, pattern of behaviour in animals . We humans have instincts as well such as fear of wild animals, fear of falling and many others. Statistics seems to be one of our innate instinct.  The basic of statistics is probability which is related to uncertainty.We can't foresee our future, thus our future is always led by uncertainty. And we have to make decisions in the face of those uncertainty by making proper analysis through our past observations and probability of occurrence in future.  Like the saying 'a burnt child dreads the fire'.
