An Introduction to Data Science and Real-World Applications
Data science combines mathematics, statistics, and computer science, in a way that helps identify patterns within data and draw insights from it. From this, data can be modelled to solve real-world problems.
What is Data Science and why is it important?
The advancements in technology and the ability to collate large amounts of data has made data analysis an easier task. Both individuals and organisations can now access real-world data with ease and this can be used to gain critical insights e.g. Organisations can gather data on consumer spending habits and use this to plan product releases.
The use of data includes not only data analysis by creating dashboards and reports, but also data extraction from multiple sources and the cleaning of that data to drive important knowledge for clarity and interpretation.
In the current job market, data science skills such as hands-on programming tools, statistical knowledge, visualisation of data and networks, machine learning and deep learning are in high demand. Jobs utilising them form the largest employable job sector with an annual hiring growth of 74% and three times as many job postings than job searches.
Data science has a versatile nature and every industry would benefit from a data scientist to interpret the data that is applicable to their field. Industries are now understanding the importance of data scientists and are hiring them not just to examine the patterns in their data, but also to enrich the usage of data which previously left unanalysed.
