What is the difference between data science and data analysis?
Data analytics focuses on describing and interpreting data to understand what has happened in the past. Data science goes further by using predictive models and algorithms to make predictions about future events.
Data Science encompasses the entire process of working with data, from data collection to data analysis. Machine Learning is a part of Data Science that focuses on developing algorithms for machines to learn and make decisions based on data.

Data Science is an interdisciplinary field that uses statistical, mathematical and programming techniques to analyze and extract meaningful information from large data sets.

Traditional statistics focuses on the collection, analysis and presentation of data, while data science goes further by including real-time analysis and the application of machine learning algorithms. This allows you to not only describe data, but also predict future events, automate tasks and make data-driven decisions in more advanced and complex ways.

We can say then that while traditional statistics focuses on specific methods to infer conclusions from data, Data Science encompasses a broader approach that includes data manipulation and visualization, as well as the construction of predictive and machine learning models.

Key skills include programming, statistics, mathematics, machine learning knowledge, visualization aptitude and data manipulation skills. In addition, good communication skills are crucial for presenting results that are often abstract, so they need to be grounded in a way that is understandable to a general audience.

It is important to emphasize that a thorough understanding of the domain in which you are working is essential.
