What Is Data Science And Why You Should Work On It?

What Does A Data Science Do?


What Is The Main Purpose Of Data Science?

Data science is an interdisciplinary field that uses scientific methods, processes, algorithms, and systems to extract knowledge and insights from noise. In Addition, Data science is part of several industries, and the demand for data scientists has increased dramatically in the last few years. Most companies are attracted to data science technologies that enable them to build a strong customer base and grow their businesses. This article covers data science, data scientists, and more.

What Is Data Science?

Data science is a topic of study that deals with big data. These data are tested and thoroughly tested with the latest software and techniques, leading to important business information and patterns. These auxiliary companies monitor statistics to formulate a successful business plan based on intelligent decisions.

Software used in data science contains the complex code algorithm used to create a model. These models are predicted. The software generates data and can be analyzed through various sources and multiple formats.


What Is the Data Science Life Cycle?

The data science life cycle consists of the following five phases:

  • Data Capture

This step is the accumulation of data that needs to be analyzed. The data collected is either structured or unstructured raw information. The tasks performed during this phase are:

  • Signal Reception
  • Data Extraction
  • Data Acquisition
  • Data Entry
  • Data Maintenance

    Raw data is collected in a single location. It also converts from the raw format to another, more user-friendly format. Tasks that are part of this phase:

    Data Staging

  • Data Processing
  • Data Architecture
  • Data Warehousing
  • Data Cleansing
  • Data Mining

Structured and processed data is slightly analyzed in this phase. Data scientists look for patterns or ranges and compare them to guess if the information is useful. The tasks are:

  • Data Mining
  • Data Summarization
  • Clustering or Classification
  • Data Modeling
  • Data Analysis

This is a thorough and essential analysis phase. Many techniques and methods are used to analyze and extract data. The process includes:

  • Exploratory or Confirmatory
  • Regression
  • Text Mining
  • Qualitative Analysis
  • Predictive Analysis
  • Data Communication

This is the last and last step in the data life cycle. The analyzed and extracted data is converted into readable information using graphs, charts, and reports. This is done in the following way:


What Is the Job of a Data Scientist?

Data scientists analyze different types of data to extract meaningful and valuable information. Data scientists are tasked with providing solutions to business problems. Follow the steps below to do this.

  • Data scientists ask the right questions to find and understand the problem.
  • Appropriate sets of variables and datasets are identified.
  • Raw data is collected in a structured or unstructured way from business records, public records, and other sources.
  • Raw data is more relevant and human Is converted to a readable format. Data is filtered to ensure accuracy, consistency, and integrity.
  • Organized, handled data is fed into an ML (Machine Learning) algorithm or a statistics model.
  • Analyze data to derive patterns, trends, and other information.
  • The data is further interpreted to find solutions to original problems.
  • Results, solutions, and insights are categorized into charts, graphs, lists, and reports.
  • Last information is imparted to the business staff.

What Are the Fields in Data Science?

Data Scientist

Data scientists look for problems and identify the right source for data extraction. These are useful for cleaning up, decrypting, mining, and presenting important data.

Skills

  • Programming knowledge of SAS, R, and Python
  • Storytelling ability
  • Data visualization
  • Statistical or mathematical knowledge.
  • Knowledge of Hadoop
  • Knowledge of SQL
  • Machine learning

Data Analyst

Data analysts are combined with business analysts and data scientists. They help to format and analyze different data formats. This allows you to provide an answer to the problem by creating an action item.

Skills

  • Statistical and mathematical knowledge
  • Programming knowledge of SAS, R, and Python
  • Expertise in data wrangling
  • Knowledge of data visualization

Data Engineer

Data engineers create, apply, manage, and improvise organizational data. These help build a healthy data infrastructure. The data engineer is also responsible for helping the data scientist transform the data into queries.

Skills

  • NoSQL databases (MongoDB and Cassandra DB)
  • Information on programming dialects like Java, Scala, and frameworks

Endnote

Glassdoor and Forbes predict that data scientists will continue to be in demand until 2026. Demand will increase by 28%. In another survey, the Data Scientist profession was ranked second in the best jobs in the United States in 2021. The average salary was reported to be $ 127,500. 

If you are interested in becoming a Data Scientist, you will need to obtain a degree such as the RMIT Online Master of Data Science. With RMIT Online, you get one from the comfort of your home. Strive for this exciting career opportunity today!
