# data science mathematics for beginners

Welcome to the training of Math for
data science professionals. This is the first lecture which is approximately of eight minutes. In this first lesson we will focus on defining what exactly is data science and how a typical data science process looks like. In Chapter one we will first start with a very very basic definition of data science then we will then take up a sample data and we will see a micro workflow of how actually data science works. Then we will redefine our definition with a more in-depth and professional definition. At the end of the lesson we have talked about two golden rules or two important rules you know which will help you to focus on learning math with data science. but the first thing is what exactly is data science? Data science is all about converting data to information. We have huge amount of data which is lying in the database you have huge amount of data which is lying in the excel sheet or wherever and we want to present that data to your management or to a decision maker in like one or two lines summary is what data science is all about. At the left-hand side I have huge amount of data of 100 days approximately and this much data if we give it to manager he won’t be able to make any kind of decision We need to take all this single
single transaction and create a summary we need to go
and create two three lines of information which can represent the summary of this data and by looking at this information the decision-maker can make better decisions which can improve the business sales or give some new dimension to the business. that’s what data science is all about. At the left hand side I have this number of days and per day what sales has been made. We can give some summary
information to the decision maker the easiest one is average,
