What is Data Analysis

Data analysis is the proccess of converting raw data into a useful information and visualize it.

Data analytics is important for removing noise/errors from the data that we are going to use.Now a days data analytics is one of the most important thing to be done before storing or accessing any data.

As we know every device stores some data. Devices we use in our daily life are much important in this century. Therefore we need to analyse data stored by devices to aquire lesser memory by having only required data. 

A simple example of Data analysis is whenever we take any decision in our day-to-day life is by thinking about what happened last time or what will happen by choosing that particular decision. 

Data analysis is about making decisions in future by predicting previous outputs of analytics.

example: you predict average of your vehicle whenever you go to some tours. You do prediction on previous calculations like to travel 50km how litrs of fuel your vehicle comsumed? 

If your vehicle goes 50km in 1 litre fuel then you will predict how much litrs will be required for 200km travelling.

This is example how data analytics works/means.
