Data science is one of the most spectacular career options these days. It has become really popular in the past decade and is expected to account for about 6% of all jobs by 2023.

Also, data science career that is likely to grow by 171% in 5 years as per the Global Industry Analysts.Other significant employers include insurance agencies, government agencies, and financial firms, apart from tech companies.

But you're here because you are amongst the smarter bunch, right?

So you don't want to jump into something that might be unsuitable or unfruitful for you.

Don't worry we've got you covered. This blog post will talk about all the pros, cons, and suitability of a data science career.

Why Is Data Science Career Such a Growing Field?

A Data Scientist is defined as someone who can "think like a computer scientist, but act like a statistician." In other words, they've mastered the art of extracting meaning from data and can solve real-world problems in an industry or business setting.

The key to success as a Data Scientist is converting unstructured data into structured & meaningful data that can then be analyzed and used to solve practical problems.

Today's world is highly data-oriented.

We are living in the Information Age, and with the massive amounts of data available today, there is a huge demand for professionals who have the skills to analyze this data and extract meaningful information.

That's where a data science career comes into play. But ironic to this, data science career is a relatively new discipline at the intersection of many different fields. The term "data science" was first used in a report issued by the White House in September 2011, and it has been gaining popularity ever since.

The term data scientist was coined around the same time as "data science," but it wasn't until recently that the idea of data scientist as a job title became common in the mainstream press.

So if you add up everything, I think it becomes pretty clear why data science is prospering so rapidly.

And I can assure you that this growth is going to continue for a long time because data will only increase with time, and so will the competition between the companies who analyze that data faster and more accurately than the other.

And don't worry if you're not sure where to get started, many universities offer programs in Data Science and Big Data Analysis, making it easier than ever before to become part of this growing field!

Skills Required to Be a Data Scientist

According to a global poll, data science's expanding popularity would result in 11.6 million employment openings by 2026.

  • But how does one go about becoming a data scientist?
  • What abilities do you require?
  • And how do you get those abilities?

Here are the core skills required to be a successful data scientist:

    • Data analysis:

      You've got data, now what do you do with it? Analyzing large sets of information can be difficult, especially when many different variables are at play.
    • Modeling:

      Once you've analyzed your data, you'll probably want to create models based on those findings. This involves making mathematical representations of real-world phenomena to be used for forecasting or predictive analysis.
    • Machine learning:

      Data scientists use machine learning algorithms to predict outcomes based on previous data sets. They also use these algorithms when building models and classifications to analyze unstructured data such as text or images.

      A background in computer science or engineering will help your understanding of these concepts but isn't necessary if you have some programming experience under your belt already.
    • Statistics:

      Data scientists need to be able to conduct statistical analysis on large datasets to identify trends and patterns.

      This involves setting up experiments and analyzing results. Some basic knowledge of statistics or calculus would be required.
    • Data mining:

      Data mining is used to discover patterns in large datasets using analytical tools such as clustering or classification models like decision trees or neural networks. It's applied in many fields, including science, medicine, and business analytics.
    • SQL and database design:

      You need to know how to query databases effectively, organize and structure your data, and design efficient database architecture. SQL (Structured Query Language) is one of the most important skills for any aspiring data scientist.

      It's a declarative language for managing data stored in relational database management systems (RDBMS). It's also one of the easiest programming languages to learn — many online tutorials provide step-by-step instructions on how to write basic queries using SQL Server or Oracle as examples.
    • Data Wrangling and Munging:

      These are two skills that allow you to manipulate your data into the desired format.

      This is important because data is rarely in the correct format for analysis, so you have to clean it up before you can analyze it.

      For example, if you wanted to find out what size shoes each person at an event wears, you would have to enter all of their shoe sizes into a spreadsheet one by one.

      This would be very time-consuming if there were many people at this event!

      So instead, data scientists use data wrangling tools like Pandas(Python Library) which allows them to use functions like 'filling()' and 'drop' 'duplicates()' in their dataset so that all of the inputs are automatically done for them by these computer programs.
    • Business knowledge:

      A good data analyst should understand business concepts and be able to apply them on the job. This will help him/her understand how data can be used to improve various aspects of the business, including marketing, sales, finance, etc.
    • Communication Skills:

      A good data analyst must have excellent communication skills to explain his findings clearly to his clients or colleagues without losing interest or confusing them with technical jargon.

      He should also be able to communicate with people from other departments within the organization who may need his help in better understanding certain aspects of their jobs or improving their performance at work.
    • A Master's Degree:

      A master's degree in data science can give you a significant edge over your competitors in the field. A degree from any reputed educational institute has a high value in the data science market.

      Apart from this, a master's degree in the domain is also going to provide you with extensive knowledge in the field and make you better versed in understanding big data.
