Top 10 Career Paths in Data Science You Need To Know

Back to blog

Data Science is an emerging technical field. It is the use of modern tools and techniques to pile up a vast amount of data to find unapparent patterns, attain significant and meaningful information out of data to help in making business decisions. So, to put it in Layman’s, Data Science is the formation of predicting models for future help using pre-existing data.

Heaps of big data are being collected, processed, analyzed, and formulated by means of Data Science via Artificial Intelligence. This field finds scope in many domains. Some major areas are:


  • Media & Communications
  • Artificial Intelligence
  • Information Technology
  • Health Care
  • Bio-Technology
  • Corporate Services
  • Sports
  • Law Enforcement
  • Marketing & Advertisements




Steps of a Data Science Job

Data Science jobs consist of five stages:

  1. Capturing: The first stage is collecting the data which might be unstructured or partially structured. It involves Data Entry, Data Acquisition, and Data extraction.
  2. Maintaining: This is the stage of Data Cleansing, Data Staging. Some data which is non-useful might be discarded.
  3. Processing: Data Scientists use the maintained data and examine patterns, motifs, and models. It requires data Mining, Data Modeling, and Data Summarization.
  4. Analyzing: This is the most important step. Processed Data is subjected to various analyses to come out with a final model. It is based on Predictive Analyses, Regression, and Qualitative & Quantitative Analyses.
  5. Communicating: This stage is shaping the Analyzed Data into easily readable forms like graphs, charts, and reports. Data Reporting and Data Visualization are key steps.
