We are living in the age of data. Businesses these days don’t make their marketing plans based on mere assumptions but rather gather relevant data, determine common trends, and devise a strategy accordingly.

Data acquisition and analysis have become pivotal in a company’s success. Businesses hire Data Scientists that can gather accurate data and use it in their favour.

Hence, data science is quickly becoming a booming field. A survey by Statista revealed that the number of companies hiring 50 or more Data Scientists grew from 30 to 60 percent from 2020 to 2021.

If you are looking to make a career in this growing and well-paying field, this article will detail what Data Scientists are, what they do, and how to become one.

What is a Data Scientist?

Data Scientists use numbers and figures relevant to a particular interest to determine trends and make inferences and predictions.

In the most straightforward words, a Data Scientist plays with numbers to help a brand move toward its goals. They gather appropriate data, turn them into a visual representation, and study trends to acquire valuable insight into a company’s marketing.

Take Facebook, for instance. The social media platform has an algorithm that studies what posts you look at, like, or respond to the most. This data, in turn, is used to offer similar posts to keep your interest in the application alive.

It is a Data Scientist’s job to develop complex algorithms that obtain accurate data, determine patterns, and use mere numbers to derive helpful information for their organisation or business.

Tasks and duties

How do enterprises decide what data to purchase and how to use it? How do they determine common trends among their ex-users that made them leave their business? Why is studying competitors and analysing their plans and success rates crucial to a corporation’s triumph?

A Data Scientist has the training to find relevant data and utilise it to answer these burning questions.

What does a Data Scientist do? A typical Data Scientist job description can include expertise in:

• Deciding what data to purchase that could help their organisation
• Sifting through the available statistics to pinpoint useful information
• Organising data into charts, tables, spreadsheets, visuals, or any other form that could bolster accurate patterns and trends
• Making predictions regarding marketing, production, consumption, budgeting, or any other aspect of a business
• Employing machine learning techniques to forecast accurate outcomes
• Using data analysis tools such as Python, SAS, SQL, or R
• Communicating findings to relevant departments and superiors.

Skills and attributes

An expert Data Scientist will deploy several skills in their work and use the latest technologies to stay on top of their game.

Here are a few tools and techniques you should master to become a Data Scientist:

• Descriptive analysis: A Data Scientist should be able to use large sets of data to study trends, correlations, and future behaviours.
• Prescriptive analysis: Use machine learning and artificial intelligence tools to produce recommendations that could steer a company towards its goal.
• Predictive casual analytics: Use various statistical methods and techniques to derive accurate forecasts for the desired outcome.
• Machine learning: Use a computer and its ability to learn from experience to gather accurate data and use it to yield precise results.
• Programming languages: A Data Scientist must be fluent in the programming language (like Python, SQL, R, or SAS) to manage and analyse big data.
• Data visualisation: Almost 7% of the company's data consists of images, videos, and graphics. Hence, data visualisation is a vital part of the job.

Data Analyst vs. Data Scientist

While the two professions are closely related, there are fundamental differences between a Data Analyst and a Data Scientist.

Just as the name implies, Data Analysts only master data analysis. They organise and study statistics to find trends and patterns that a company could use to their benefit.

However, a Data Scientist’s job is much more significant. Their work includes data acquisition, organisation, analysis, development, and incorporation to run operations smoothly towards the end goal.

A scientist is expected to develop models, find problems, look for solutions, and give recommendations to help their team. However, it is not uncommon to start your career as a Data Analyst and later upgrade to a Data Scientist with adequate experience and expertise.

How to become a Data Scientist?

A four-year bachelor’s degree, a minimum of one year of master’s, and a year of gaining proficiency in the practical field will turn you into a data science professional.

Glassdoor ranked data science among the top three jobs in America for five consecutive years. But Data Scientists are in high demand all over the world. No wonder more and more young people are opting for a career in it.

If you are wondering how to be a Data Scientist, here is a simple three-step process for you:

• A Bachelor’s in IT, computer, business, mathematics, statistics, or related field
• A Master’s in data science
• Hone your data management skills
• Gain experience in your desired niche.

Education requirements

When you are out to get a job as a Data Scientist, a solid, relevant educational background is bound to impact your CV. A degree in information technology, statistics, mathematics, computer sciences, or business may help stretch your legs in the field.

Data Scientist Qualifications

A bachelor’s in any of the following relevant fields will help you get started:

• Mathematics
• Applied mathematics
• Computer science
• Statistics
• Economics
• Social science
• Physics

Several universities offer a master’s program in database administration or data science to top it off. These Data Scientist qualifications are not required but will build your credibility when applying for a job.

Also, since 79% of the people who pursue data sciences professionally have a bachelor’s and 38% a Ph.D., to increase your chances of beating the competition out there, a master’s or a doctorate is the best degree for data science.

Work experience requirements

While it is not a mandatory Data Scientist career path, starting as an entry-level Analyst may provide you with the necessary work experience and expertise.

You will find several roles offered by different companies that rely heavily on data. Seek a position as a Data Analyst, Data Engineer, Statistician, or Intelligence Analyst. These jobs will lay the groundwork from which you can broaden your horizons.

Data Scientist career path

Just like any other field, as a fresh Data Scientist, you will need a job to gain experience in the area. Next, you can land a better position through extensive training, hard work, and expertise.

Jobs

The shortage of expert Data Scientists renders the field pretty high-demand. A survey in 2019-20 concluded that one of the top three challenges marketers face these days is the lack of Data Scientists to analyse their numbers and trends.

Hence, you can expect to land a suitable job to boost your career. Also, the work environment is subjective to a business’s nature and your coworkers. However, the job itself is pretty fast-paced and ever-changing.

You will need to find, organise, and use numbers and master a new trick to do it every day. One of the downsides of the job is that as soon as you learn one technique, it will be old news, and the market will thrust a new one to master.

But the high demand and a handsome payout attract large numbers of professionals to the field.

Salary

According to Glassdoor, an average Data Scientist in Australia makes approximately AU$120,000 per year, a senior Data Scientist makes AU$152,500 per year, while the lead Data Scientist makes AU$153,750 annually.

Below is a chart that shows the annual salaries of a Data Scientist in Australian dollars at a few local corporations:

All stats and graphics point to one conclusion: data science is a well-paying field. Whether working at a big enterprise or a small startup, a Data Scientist is bound to have an income above the national average.

Outlook

Deloitte predicts that the Data Scientist workforce will increase from 301,000 to 339,000 in 2021-2022. This puts the Data Scientist position at an expected growth rate of 2.4%, which is significantly stronger than the 1.5% yearly growth average for the rest of the Australian labour force.
