Data Science with Python Certification

What is Data Science

Data Science has become a popular career choice in Arlington, Texas. Arlington is known as the center of a web that connects hundreds of federal labs, universities, and corporations in the States. It is also home to many leading companies, such as Life Corp, DolEx Dollar Express, D R Horton, Double B Foods, The Pinnacle, etc. Not just in Arlington, data science has become a boon for many companies around the world. Data Science was also named as the Sexiest job of the 21st century by the Harvard review in 2012. Major companies collect data from users, sell them to the ad companies, and make major profits. How else do you think Amazon knows what to recommend to you when you didn’t even ask for it? The answer is simple, data. Here are some of the reasons that make Data Science the sexiest job of the century:

  1. More and more companies are shifting to data-driven decision making.
  2. We still don’t have enough qualified and experienced data science professionals. So, professionals who are skilled in this domain have the opportunity to get the highest salary in the IT industry.
  3. Today, we are producing more data by the second. When data is collected at such a high rate, it requires great effort in analyzing it. It is the job of a Data Scientist to use this raw data and help the organization make crucial marketing decisions based on it.

Living in Arlington has many advantages as it is home to many universities renowned for data science degrees, such as Southern Methodist University, Tarleton State University, Texas A & M University-College Station, Texas Tech University, etc. You can also opt for online courses and learn at your own pace. If you want to become a Data Scientist, you need to be skilled in the following:

  1. Python Coding: In the field of Data Science, Python is one of the most commonly used programming languages. The simplicity and versatility that Python offers make it the best language for processing of data. It can also take various formats of data. With the help of Python, Data Scientists can create and perform operations on a dataset.
  2. R Programming: If you want to become an expert Data Scientist, you need to have a thorough knowledge and understanding of an analytical tool. R programming makes the problem easy for the data scientists to solve.
  3. Hadoop Platform: Though it is not a requirement, the Hadoop platform is used in several data science projects. So, it is better if you get acquainted with the platform. After doing a study on 3940 jobs on LinkedIn, it was concluded that Hadoop is a leading skill requirement for a Data Scientist.
  4. SQL database and coding: Structured Query Language or SQL is a database language that can be helped in accessing, communicating, and working on the database. MySQL is another such language that uses concise commands and makes the operating process on a database easier by decreasing the technical skills requirement, and therefore saves time.
  5. Machine Learning and Artificial Intelligence: If you want to pursue a career in Data Science, proficiency in Artificial Intelligence and Machine Learning is a must. This requires being familiar with the following concepts:
    • Neural Networks
    • Decision trees
    • Reinforcement learning
    • Logistic regression
    • Adversarial learning
    • Machine learning algorithms, etc.
  6. Apache Spark: Currently, Apache Spark is one of the most popular technologies in the world for data sharing. Like Hadoop, it is used for big data computation. The only major difference between the two is that Apache Spark is faster. This is because Spark uses the system memory to make a cache of its computation while Hadoop reads and writes to the disk. Apache Spark is used to run the data science algorithms faster. It helps prevent the loss of data and can handle complex unstructured datasets. While dealing with large datasets, Spark helps disseminate data processing. The speed with which it operates adds to its advantages. It helps the data scientist carry out the project with ease.
  7. Data Visualization: A data scientist may be able to make sense of the raw data but not every other person shares that skill. It is the job of a data scientist to visualize the data in a format that could be understood by non-tech members of the organization. There are a number of visualization tools for that like Tableau, d3.js, matplotlib, and ggplot. After a number of processes are performed on a dataset, these tools help the data scientists convert the complex results obtained into a format that can be easily understood and comprehended. These tools even help the data scientist quickly grasp insights and provide the right outcome. The organization also gets the opportunity to work directly with the data.
  8. Unstructured data: When it comes to data, most of it is in complex, unstructured form. It is neither labeled nor organized into database values. A data scientist must have the skill to work with this unstructured data. Some of the examples of this unstructured data include social media posts, videos, blog posts, audio samples, customer reviews, etc.

Being a successful data scientist involves incorporating the following behavioral traits:

  • Curiosity – The field of data science involves dealing with a massive amount of data every day. A data scientist must be curious and have an undying hunger for knowledge. Otherwise, it can get too hard too soon. 
  • Clarity – If you are constantly asking questions like ‘how’, ‘why’, and ‘so what’, Data Science might be the perfect field for you. Since the amount of data is so large, getting clarity is very important. During data cleaning or writing code, you must know exactly what you are doing and why you are doing it.
  • Creativity – Creativity is a must in a Data Scientist. It is their job to develop new tools, create new modeling features, and find new ways for data visualization. You need to have the skills to know what is missing and what must be included to get the right insights and outcome.
  • Skepticism – This is what draws the line between a data scientist and a creative mind. It is important for a Data Scientist to be skeptical and keep their creativity in check. This helps them to not get carried away with creativity and stay in the real world.

Arlington is home to many leading companies, such as Life Corp, DolEx Dollar Express, D R Horton, Double B Foods, The Pinnacle, etc. Also being the sexiest job of the 21st century, data scientists enjoy certain benefits over other professions. Here are the 5 proven benefits of being a Data Scientist:

  1. High Pay: When it comes to looking for a job, high pay is expected. Data Science jobs are currently enjoying the boost as compared to other career options. With Data science, the expected remuneration is extremely high. The average salary for a Data Scientist is $68,020 in Arlington.
  2. Good bonuses: When you join a company as a Data Scientist, you will enjoy several perks like signing bonus, equity shares, and impressive bonuses.
  3. Education: Being a data scientist involves getting a Masters or a Ph.D. In this field, knowledge is in great demand. Also, with a degree, you can work as a researcher or lecturer in a government or a private institution.
  4. Mobility: A data scientist job can get you a job in one of the developed countries. This comes with a hefty salary and help improves your living standard.
  5. Network: A data scientist gets to network with other professionals in the tech world through conferences, tech talks, and other platforms. You can use this opportunity for referral purposes. You can also get a research paper published in an international journal.

Data Scientist Skills & Qualifications
