Data analysis is the process of transforming your data into insights that can help you evaluate the impact of your news stories. Depending on the type of questions you want to answer, data analysis can be descriptive, inferential, or predictive. Descriptive analysis summarizes and visualizes data using charts, graphs, tables, or dashboards. Inferential analysis tests and compares data using hypotheses, models, or experiments. Predictive analysis forecasts and estimates data using algorithms, machine learning, or artificial intelligence. To analyze data, you can use various tools such as spreadsheets and databases to organize and store data in a structured format, statistical software and packages to perform calculations and operations on data, data visualization and reporting tools to present and communicate data in a clear manner, as well as data science and analytics platforms to apply advanced techniques and methods to your data.
