Data science is a multifaceted field that requires a diverse set of skills spanning statistics, programming, data manipulation, machine learning, and domain knowledge. Here are some core skills that are typically expected of a data scientist:
Statistics: A strong foundation in statistics is crucial for data scientists to understand data distributions, make inferences, and draw meaningful conclusions from data.
Programming: Proficiency in programming languages such as Python or R is essential for data manipulation, analysis, and building machine learning models.
Data Manipulation: Data scientists should be skilled in cleaning, transforming, and preprocessing data to make it suitable for analysis. This often involves working with tools like pandas in Python or dplyr in R.
