Quick answer<\/span>

What is Data Science?<\/h2><\/div>\n

Data Science is the use of data, Mathematics, Statistics, computing and subject knowledge to answer questions, identify useful patterns and support decisions.<\/strong> NIST defines the field around the combination of domain expertise, programming skills, Mathematics and Statistics used to extract meaningful insights from data.

Your starting point<\/span>A useful question<\/strong>Begin with something you genuinely need to understand\u2014not with an algorithm.<\/small><\/div>\n
Your advantage<\/span>Know the subject<\/strong>Engineering, health, agriculture, business or another field gives the data context.<\/small><\/div>\n
Your added skill<\/span>Analyse the evidence<\/strong>Use Statistics, SQL, Python and visualisation as the problem grows.<\/small><\/div>\n<\/div>\n\n
