Analytics: Exploring Ways to Infer Relevancy in Data

Leveraging fast-growing data sources that can be used for capture and analysis is one of the biggest business challenges that market leaders face today. The amount of data getting generated every day is almost 2.5 quintillion bytes and the possibility of relevant data is also huge. Thus, regardless of whether the data is from a machine or from other sources, relevant analytics allows you to discover important information that would otherwise be hidden.

Analytics Exploring Ways to Infer Relevancy in Data

According to Indeed, the five most important skills for a Data Scientist listed in their job portal are:

  • Machine learning
  • Python
  • R
  • SQL
  • Hadoop

Nine out of ten jobs require at least Python, R, and/or SQL as important skills of a Data Scientist. According to the same report, these skills are closely related to the roles and responsibilities that aspiring Data Scientist should learn. Thus, these Data Scientist skills will make you eligible for almost 70% of all online positions in the Data Scientist’s role. Extending your Data Scientist roles and responsibilities beyond these ​​will allow you to earn higher salaries.

In a data-driven organization, your stakeholders rely on you to help them make decisions. To do this, you need to know what, when, and how to use which machine algorithms. Your choice will make or break the answer to a business problem. Statistics provide the means/tools necessary to drill down into the data and gain valuable insights. The more statistics you know, the better will be your analysis and quantification of uncertainty in a dataset. Therefore, “analyzing data with statistical knowledge is one of the most critical Data Scientist roles and responsibilities to transforming yourself into a successful Data Scientist.

Collaboration with Stakeholders

A Data Scientist works with various database types to capture and process real-time distributed data. As a result, existing companies design and develop custom systems for capturing, managing, and retrieving data to support the analysis and dissection of complex and large datasets. As a Data Scientist:

  1. You will be responsible for supporting the development of computing resources and custom enterprise-level tools to be used by analysts, developers, and other professionals.
  2. Not only do you need to focus on developing computer systems, but you also need to work closely with stakeholders, CIOs, and other teams to develop various sorts of requirements.
  3. You must learn to design, develop, and implement the most appropriate solutions for your business and share them with your stakeholders. This requires preparing Big Data, creating databases, and implementing relevant data models.

Data Scientists work closely with marketers, decision-makers, and other stakeholders in their projects and products to channelize/communicate all possible outcomes. This type of collaboration has proven to be a huge achievement and is often considered one of the most important Data Scientist roles and responsibilities.

Business Understanding: Dealing with Business Problems and Finding the Best Solution

Data Scientists know more about statistics than any software developer and know more about software development than any statistician.’ Josh Wills, Director, Slack.

Data Scientists combine data, computing, and technology to gain valuable insights by leveraging the business levers available to them. They play leading roles in managing a range of business support projects that require them to leverage and synthesize large amounts of data to enhance a company’s trends and outcomes and decision points. Also, Data Scientists are responsible for:

  1. Advising companies on data potential
  2. Gaining new insights and transforming them into business goals
  3. Developing solutions that improve business performance through advanced statistical analysis, data mining, and data visualization technologies.
Certification in Bigdata Analytics

Strategy/Design: Interacting with In-house Teams and Customers

One of the Data Scientist’s roles and responsibilities preclude dealing with business problems and finding potential solutions.

  1. There are two strategies to help you work more quickly: asking questions and building relationships. When you ask a question, you can get to know the details of your work faster. When you establish a relationship, you can understand the context of the roles in your organization.
  2. A good way to learn is to interact with people. Not only can you ask questions and get answers, but you can also see how they find the answers. If it’s a technical issue, you can also look at the coding environment and learn about new ways to intuitively solve it. Even if you want to know how to retrieve data, you will know which table you can get it from, which table to refer to, and coding techniques. Thus, you can answer as many questions as possible just by finding out where to look.
  3. Again, you should try to meet all the stakeholders you will be working with. If the Data Science team is new, try to meet them. In case, you have a Data Engineer or a Data Analyst working with you, collaborate with them.
