Thank you for quick response.
But the tools mentioned by you are suitable for data containing numbers. But Data doesn't mean only numbers. It may include text, audio, video, etc., Are there any tools which analyses forms of data other than numbers?
Very Informative Article. I am pretty much convinced that a manager should use data to make better decisions. Data has to be analysed well to get better insights. Can you please mention some of the analytical tools available to manager to help him/her in decision making.
