Descriptive statistics: Descriptive statistics are used to describe the data in a dataset. They can be used to calculate the mean, median, mode, and standard deviation of a dataset.
Inferential statistics: Inferential statistics are used to make inferences about the population from which a sample was drawn. They can be used to test hypotheses and estimate confidence intervals.
Machine learning: Machine learning is a type of artificial intelligence that allows computers to learn from data. It can be used to classify data, predict future events, and make recommendations.

Data Visualization Tools

Data visualization tools are used to create visual representations of data. This can make it easier to understand the data and identify trends and patterns. Some of the most common data visualization tools include:
Charts and graphs: Charts and graphs are used to display data in a visual way. They can be used to show trends, patterns, and relationships in the data.
Maps: Maps are used to display data that is geographically distributed. They can be used to show the distribution of customers, sales, or other data.
Dashboards: Dashboards are used to display a variety of data in one place. They can be used to track key metrics, monitor progress, and identify trends.

Conclusion

Data analytics is a powerful tool that can be used to extract valuable insights from data. By understanding the different types of data, the different techniques used to analyze data, and the different tools that are used to visualize data, you can use data analytics to improve your business, your healthcare, or your government.
