Career Paths for Data Science and Recommended Courses

Each time you post an article, message, or video to Facebook, click a link, or buy anything online, you’re generating data. With more than 3.5 billion internet users and 2 billion mobile phone users, that’s a lot of data.

As data has increased, so has its ability to be collected, organized, and analyzed. Digital data storage is cheap compared to before. Processing power is more powerful than ever before. 

And tools and software are available to analyze the large amount of information that is available for business intelligence. In the last few years, data analysis has carried out everything from predicting stock prices. 

The very first step on your path to a professional in the field of data? Assessing your primary career options: Data Analyst, Data Scientist, and Data Engineer.

Data Analyst

Data analysts should have a background in at least five core competencies: programming, statistics, machine learning, data munging, and data visualization. Beyond their own technical expertise, data analysts must have a strong understanding of these core skills in addition to presentation abilities.

Required Skills

Data analysts should have a general knowledge of five fundamental skills: programming, statistics, machine learning, data munging, and data visualization. In addition to technical knowledge, attentiveness and interactive skill are important to be successful as a data analyst.

Recommended Courses

Step 1. Become a Data Analyst

Data Scientist

Some companies treat the titles “Data Scientist” and “Data Analyst” as interchangeable terms, but there’s an essential distinction between them. The data science expert is good at solving complex data-related problems. 

The data analyst knows how to analyze different kinds of information and communicate with it effectively. Data Scientists are in high demand, but there is currently a shortage of them in the workforce. 

Acquire programming skills, data wrangling, machine learning, experiment design, and data visualization skills, and launch a career in data science.

Required Skills

Compared to a data analyst, a data scientist looks at data from multiple resources. Data Scientists use tools such as Hadoop (a commonly used framework for data processing), they use programming languages such as Python and R, and they apply the practices of advanced mathematics, statistics, and information theory.

The Starting Point

Data analysis is a swiftly developing field with many voices sharing what you will need to know and in what order. The available information may be challenging, overpowering, and discouraging. 

Keep in mind that the information we just shared is a guide to what you need to know to land your first data analyst job. You can use this information as a starting point, depending on your specific background.

No matter how much experience you have, the initial cost to enter the data analysis field is high. You need to be focused and determined if you want to make it in this field. Nevertheless, your reward for your efforts is bigger.

Tomorrow of Data

According to SAS, The definition of Predictive Analytics is “the use of data, statistical algorithms and machine learning techniques to identify the likelihood of future outcomes based on historical data. The goal is to go beyond knowing what has happened to provide the best assessment of what will happen in the future.”

In a recent TDWI study, the top five factors driving companies toward Predictive Analytics: predict trends, understand customers, improve business performance, drive strategic decision-making, and predict behavior. 

More companies are using predictive analytics in their data processing strategies. Markets and Markets reported that “the global predictive analytics market size to grow from UDD 10.5 billion in 2021 to 28.1 billion by 2026.”       

As Predictive Analytics has gained popularity, its benefits are becoming ever more important. The ability to build such forward-looking analysis is quickly becoming an important part of any business’ competitive edge. However, effectively conducting data analysis now requires two things: data management tools, and people who can use them.    

Conclusion

As we have mentioned in the introduction to this guide, a career in data is both secure and safe. We’ve also provided an overview of why pursuing a career in an employment area is an excellent choice for so many people. 

No matter what you choose to do, there are some basic skills and abilities you will need. However, data provides a range of opportunities with different entry points.
