Difference between Data Science and Data Analytics

The main difference between Data Science and Data Analytics is in their area of work and domain expertise as we know that data analytics is a subset of data science. Data analytics is a work on filtering out data for representation that is meaningful to key stakeholders, while data science is a process to dive deep into data to make some statistical conclusions to make important business decisions.

This Venn diagram explains the interrelationship between data science and data analyst

What is Data Science?

Data science Is a multidisciplinary field which requires to work on the data available on different sources, structured or unstructured and then structuring the data correctly, mining it, making applicable assumptions, building association models, proving causality, and penetrating the data for symbols of anything that can carry business collision throughout.

How does Data Science Work?

Data science has different domains you have to master pertaining to computer science, data architecture, mathematics, and statistics. Data science involves research, finding data sources and asking correct questions which are later answered in data analytics.

Example

In a business scenario: where an organisation wants to finalise the vender and they have not much of data pertaining to vender performance based on quality, productivity, delivery etc. data science will solve this problem by using algorithms to establish required data architecture and data mining to pull out data doing research and then use hypothesis test for validation of assumption to conclude about vender performance or come out with data requirements and structure necessary for making the decision.

Skills required in Data Science.

  1. To become an expert in Data science, you need to master necessary skills for positions in different companies and organisations.
  2. Data Integration
  3. Deep Learning
  4. Big data
  5. Soft skills
  6. Functionality
  7. Programming
  8. Data Sourcing
  9. Machine Learning

What is Data Analytics?

Data analytics is a field where the main goal is to take out meaningful information out of existing data (generally not organised and are present in an ad-hoc manner) by organising and managing data and getting required inference and findings to present them to key stakeholders and business owners using visualisation tools

How does Data Analytics Work?

Data analytics answers all questions required to answer from a business point of view for the concerned organisation. Distinctive data analytics comes from the field of science, technology, engineering, or maths degree. Though, data analytics require well-built skills in programming, maths, science, databases, modelling, and analytics.

Example

Let us assume that a business wants to see; how the advertisement is affecting customer interest in the product. They have existing data like social media activity, OTT platforms, field data, surveys (not well organised to work on) from lots of data sources. Data analytics will help in organising data and do the data mining, deduce an ideal result, and present the findings to process owners that will be channelled into marketing strategy moving forward.

Skills required in Data Analytics.

  1. Some of these top skills for data analytics comprise:
  2. Microsoft Excel
  3. Data Visualisation
  4. Presentation Skills
  5. Critical Thinking
  6. Machine Learning
  7. R or Python-Statistical Programming
  8. Structured Query Language
Data Science Data Analytics
1.They are familiar with database systems like MySQL and Hive etc.   Familiarity with data warehousing and business intelligence concepts  
2.Knowledge of R(optional), Python and java   In depth knowledge of SQL and analytics  
3.In depth knowledge of Statistics, mathematics, and data interpretation   Strong knowledge of Hadoop based analytics (HBase, Hive, MapReduce, Impada Etc.)  
4. Speciality in Hypothesis testing and correlation and data mining and predictive analysis   Data storing and retrieving tools and strong grip on data architecture.  
5. Prediction of business decisions. Deep analysis of data to take important decision.   Familiar with various ETL tools- for transforming different source of data into analytics data stores.  
6. Deep statistical insight and machine learning – Mahout, Bayesian, Clustering etc.   Should also be able to make some critical business feature real time.  

Difference between Data Scientist and Data Analyst?

The main difference between Data scientist and data analyst is their roles. Data analysts work with existing data sets for representation that is meaningful to key stakeholders, while data scientists work with raw data to make some statistical conclusions to make important business decisions. Data scientists use statistics, big data, Statistics, Python, SQL, data mining while Data analysts use python, data visualisation like BI or Tableau, MS office, Structured query language etc.

Comparison between roles of data analyst and data scientist.

Data Scientist

Data scientists predict the requirements necessary for business decisions which need to be taken for organisational profit, independent of whether the existing data is present or not. They are experts in computer science, statistics, and data mining. Data scientists have a good experience in business driven by data which helps them to arrive at a solution to complex business problems.

Characteristics of a Data Scientist

Data scientist comes from a research background with sound knowledge of Programming, statistics and data mining and business. The key skills of a data scientist are Data Integration, Deep Learning, Big data, soft skills, Functionality, Programming skills, Data Sourcing, and Machine Learning. They have a lot of experience in doing work in ad hoc situations and they do proper communication to the management as and when required.

Roles and Responsibilities of a Data Scientist

  • Identify valuable data sources and automate collection processes
  • Undertake pre-processing of structured and unstructured data
  • Analyse large amounts of information to discover trends and patterns
  • Predictive modelling and extracting data through data mining.
  • Build predictive models and machine-learning algorithms
  • Combine models through ensemble data modelling
  • Present information using data visualisation techniques
  • Propose solutions and strategies to business challenges
