What Do Data Scientists Do?
On your first day as a data scientist, you may be tasked with joining a team of professionals responsible for developing solutions - or making predictions - for a company's future. This process begins with the identification of the problem or the specific area that companies are interested in exploring for future growth.
Assess Business Goals
As an example, your organization may be looking for trends within financial data, analytics about public interest, or even data that shows overall growth of the organization. It is then your job to identify different data sets and variables that can provide you with the most information for the questions being answered.
Extensive Data Collection
Once you have determined what type of data you need to review, you can begin the data collection process. This may include searching through several different sources in order to pull large amounts of raw data that you can then break down and further analyze.
Analyze Data Variables
Pulling large sums of raw data is not the final step before your final analysis process. Usually, large amounts of data may be filled with errors and may require proper cleaning before it can be interpreted.
Data Cleansing and Validation
Cleaning and validating the data can then be followed up by your application of data models and algorithms to mine the data that are working with.
Your next step in this process would be to conduct a thorough analysis of the data in order to identify patterns and draw useful information from it.
The information gained through this process can then be communicated to your organization through formal reports, graphs, or even PowerPoint presentations that represent what was learned through the data.
This information can help during the decision making process, when establishing areas of change, or when solving complex and hidden problems with growth.
Salary and Pay for Data Scientists
Data Scientists can work in a wide variety of settings from the very beginning of their careers. Depending on the type of position you choose to take, you might find that the roles and responsibilities can vary from place to place, as well as the pay.
In order to give you a better idea on what to expect in terms of earnings in this field, our team of educational experts has researched some common career titles for graduates of Data Science degree programs and their respective careers.
The list below shows some of the average salaries for actual professionals working in the field today. Take a look through the different options to see which area of Data Science might be the best option for you to pursue.
- Computer Research Scientists: $118,370 on average per year (BLS).
- Database Administrators: $90,070 on average per year (BLS).
- Statistician: $88,190 on average per year (BLS).
Recommended Courses for Data Scientists
As you transition into degree programs that can assist you with learning the necessary skills to become a successful Data Scientist, you can expect to take an abundance of courses that dive deep into the individual skills that combine into your overall framework of expertise.
Some of the most important courses that you might take during your experience can include Applied Statistics, which can outline topics such as descriptive statistics, data analysis, statistical inference, and probability theory. This course can lay the foundation for building upon your skills in statistics that can then be used in an organizational setting in the future.
Practical Machine Learning
Courses like Practical Machine Learning can also contribute to your repertoire as an upcoming Data Scientists. While not all professionals in this field work directly in this specialization, students in this course can gain knowledge in principal components analysis, artificial neural networks, and even re-sampling techniques.
Data Modeling and Data Visualization
Data Modeling and Data Visualization are also important classes that you should look out for when reviewing potential degree programs to enroll in. Skills drawn from these courses can help you to develop a strong understanding of models and how they are implemented during data analysis, as well gain a better understanding of how presentation of data should be handled when delivering results to clients.
Essential Software Programs for a Data Scientist
As a new Data Scientist in the field, it can be important to be in the loop about popular software used in the field.
One of the most popular software options in the field today is Apache Spark, which is a powerful analytics engine that provides scientists with many different tools designed to help make accurate predictions using large sums of data.
SAS: Statistical Analysis System
Data Scientists working for large commercial organizations may utilize SAS (Statistical Analysis System) as their primary functioning software, which offers users a wealth of statistical libraries for modeling and reviewing large amounts of data.
This type of software is generally more expensive than others and might only be found in larger organizations with a great data analysis need.
If you are seeking a career in the machine learning environment, its possible that you might run into software such as BigML during your experience. Primarily in a cloud-based GUI environment, BigML utilizes machine learning algorithms for forecasting, determining risk, and progressive innovation.
