Introduction to data science

Data science helps the user by providing an ability to analyze huge data sets and by doing necessary operations, data science will save precious time and makes some big profit out of it.

Description

Data science is very much popular in today’s world scenario as there is a huge amount of data generated each day in different fields like mart, hospitals, colleges, etc.

Users need to perform some operations by analyzing the dataset and then find something useful from that data.

For example- Suppose there is a dataset of a mart, which contains data for 4 users.

Users Last visited Last bought products Average amount spent each time Number of times visited in last month Most bought products
Abhishek 13th Jan Milk, eggs, bread, juice 200 10 Eggs, juice
Aditya 20 Jan Cabbage, wheat, rice, soft drinks 500 5 Soft drinks, rice
Rahul 23rd Jan Rice, pulses, wheat, ice cream, snacks, eggs 1000 4 Eggs, wheat
Sneha 15th Jan Chocolates, Corn flakes, pen, tea bags 300 3 Chocolates, tea bags

From above data, mart will predict products needed for each user and it will also predict when this user will be going to visit their mart.

For Sneha, mart knows that she will visit the shop for minimum 3 times in a month.

So, next date will be in the last week of January and recommended product will be chocolates and tea bags. Along with that mart will suggest some products so that she will be spending amount approx 300.

Solution to the problem should be logically solved by using mathematical skills and specific tools like R studio. Data science is a medium to analyze real-time data that enhance clarity and give the right solution to an enterprise.

Data Science vs. Data Analysis

It’s very important to know that data science and Data analysis are little similar but, there so many differences between them. Let’s check out the differences

Data Science Data Analysis
Providing strategic actionable insights into the world Providing operational observations into issues
Mathematical, technical and strategic knowledge are mandatory Data analysis and visualization skills required
Deal with big data Not necessarily deal with big data

In brief, with the help of data science, we will be able to analyze datasets, understand it and by performing necessary operations, we will get the resultant which will be beneficial for users.
