Top 5 data analysis skills to learn in 2024
The world of data analysis is constantly evolving, so it's important to stay up-to-date on the latest skills and technologies. Here are the top 5 data analysis skills to learn in 2024:
Python
Python is a general-purpose programming language that is widely used in data analysis.
It is relatively easy to learn, even for those with no prior programming experience.
Python has a large library of data science tools and libraries, such as NumPy, Pandas, and Scikit-learn.
These tools and libraries make it easy to perform common data analysis tasks, such as data cleaning, data manipulation, and statistical analysis.
SQL
SQL is a database query language that allows you to retrieve and manipulate data from databases.
SQL is an essential skill for any data analyst, as it allows you to access and analyze large datasets.
There are many different SQL dialects, but the most common is ANSI SQL.
Most major database vendors, such as MySQL, PostgreSQL, and Oracle, support ANSI SQL.
Machine Learning
Machine learning is a field of artificial intelligence that allows computers to learn without being explicitly programmed.
Machine learning is used in a variety of data analysis applications, such as fraud detection, product recommendation, and customer segmentation.
There are many different machine learning algorithms, but the most common include linear regression, logistic regression, and decision trees.
Cloud Computing
Cloud computing platforms like AWS and Azure provide a variety of data storage, processing, and analytics services.
Cloud computing is essential for handling large datasets, which can be too expensive and time-consuming to store and process on-premises.
Cloud computing platforms also offer a variety of tools and services that can be used for data analysis, such as Amazon Athena and Azure Data Studio.
Data Visualization
Data visualization is the process of presenting data in a way that is easy to understand and interpret.
Data visualization tools like Tableau and Power BI allow you to create interactive charts, graphs, and maps.
Data visualization is an important skill for data analysts, as it allows them to communicate their findings to others in a clear and concise way.
Here are some specific examples of how these skills can be used in data analysis:
Python: Python can be used to clean and prepare data for analysis, build machine learning models, and create data visualizations.
SQL: SQL can be used to query and analyze data from databases, such as customer databases, financial databases, and sensor databases.
Machine learning: Machine learning can be used to identify patterns in data, make predictions, and develop recommendations.
Cloud computing: Cloud computing can be used to store and process large datasets, run machine learning models, and create data visualizations.
Data visualization: Data visualization can be used to communicate data analysis findings to stakeholders in a clear and concise way.
How to build a strong data portfolio
