The applications of data science are numerous, the data-driven technologies have already taken over the world which is creating havoc! These techniques can be learned from why is data science important in the 2021 blog.

What are the stages involved in Data Science?

Defining the Problem – Before you get into why is data science important in 2021, you need to first define what your business problem is, what is that you want to achieve, and what are the different parameters on which your final results depend.

For example, before launching a product companies usually try to understand the consumer psyche, their purchasing behavior, and based on these parameters they shortlist the right product for their customers.

Obtaining the Data – Obtaining the data based on the parameters defined in step 1, pull out the data. This involves thinking through what data you will need and finding ways to get that data in place. Whether it is querying internal databases or purchasing external datasets. Collecting the appropriate data takes 19% of the total time spent in the process.

Scrubbing/Cleaning the Data – This process is for us to clear or say filter the data, where the data is converted from one format to the other and consolidated into one standardized format. A few things to jack for are – missing values, corrupted values, such as invalid entries, time zone differences, and data range errors. Data cleaning itself takes 60% of the total time spent during the process.

Exploratory Data Analytics – First of all you need to inspect the data and its properties. Different data types like numerical data, categorical data, ordinal data, and nominal data require different treatments. Moving forward to compute descriptive statistics to extract features and test significant variables. You will have to look into some of the interesting patterns that can help explain why sales are reduced for this group.

Data Modeling – It is the process of producing a descriptive diagram of relationships between various types of information that are to be stored in a database. Something as simple as an online transaction can be broken into items sold, user demographics, time of sale, etc.

Data modeling is used to create the most efficient method of storing information along with providing for complete access and reporting.

Data Visualisation – This is a graphical representation of any data or information. Visual elements such as charts, graphs, and maps are the few data visualization tools that provide the viewer with an easy and accessible way of understanding the represented information. It allows you to easily grasp information, establishes relationships between elements, and provides intuitive, personalized, and updatable data.

Why is Data Science important in 2021 for businesses? 

The value of data has now surpassed oil which itself shows the remarkable journey of data in the field of science and the data scientists will be of paramount importance for businesses across many verticals.

Data and science are interconnected.

Every data generated needs to be read and analyzed to drive out meaningful interpretations. Scientific processes must be employed so that insightful data-driven solutions can be achieved.

Data create better customer experiences.

For goods and products, data science will be leveraging the power of machine learning to enable companies to create and produce products that customers will adore. For example, for an eCommerce company, a great recommendation system can help them discover their customer personas by looking at their purchase history.

Data will be used across domains.

Data science is not limited to only consumer goods or tech or healthcare. There will be a high demand to optimize business processes using data science from banking and transport to manufacturing. So anyone who wants to be a data scientist will have a whole new world of opportunities open out there. The future is data.

What makes a data science job so desirable?

Considering the basic laws of economics- supply, and demand, the demand for data science professionals is very high and the supply is too low.

According to extensive joint research performed by IBM, Burning Glass Technologies, and Business-Higher Education Forum, this tendency will continue to be strong for the years to come. 

This by itself, determines that the salaries will be outstanding. Consequently, people are extremely willing to get into data science.

From big MNCs to small startups, every organization needs a Data Scientist for proper usage of the surplus amount of data it generates and stores. There is a broad scope of data science in the present as well as future scenarios.

Where does the demand come from?

Data-driven decision-making is increasing in popularity. While in previous years, analysts would use software like Excel to analyze data and only academics would turn to SPSS or Stata for their statistical needs.

Now, almost anyone can have access to and use a data-crunching tool. Infect, advancements in technology have brought about things like:

  • Digital marketing cloud-based data services. Eg: Google Analytics
  • Complicated ERPs for data breakdown and visualizations. Eg: SAP, Microsoft dynamics
  • Data visualization tools for business intelligence. Eg: Power BI and Tableau

With these tools, analysts can visualize the data and drive out ways to uncover insights.

Nevertheless, there are also outstanding improvements in prog languages like R and Python, which let you perform complicated analyses with just a few lines of code.

However, these tools are very user-friendly and organizations can easily afford to employ people to take advantage of these tools which would quadruple their business in a short period.

Few examples of Data Science- centric Industries

Google: Google is the embodiment of data science. Everything they do is data-driven, be it their search engine( or their video streaming service (YouTube) or maximization of ad revenue with Google Ads, and so on. Even their HR team uses the scientific method to evaluate strategies that make the employees feel better at work, thereby making them more productive.

Amazon: While purchasing anything from their website you are often flooded with recommendations, these are the results of Amazon’s sophisticated data science algorithms. They have implemented an algorithm that can predict with great certainty if you are going to make a conversion.

If the probability is high they may move the item to the storage unit closest to you. This way when you purchase the product, it is delivered the next day or in some cases the same day.

Facebook: Facebook is a bunch of websites and apps most notably Facebook Messenger, Instagram, Whatsapp for now. Facebook is generating ad revenue at large since it has all the intimate data for all its users.

Most of us engage with all their platforms which makes them learn our preferences and shows related content. This creates a marketing niche that makes companies use Facebook as an advertising medium.

Even small businesses, blogs, local businesses now use Google Analytics for meeting their needs and making huge profits off them.
