How do descriptive statistics differ from inferential statistics?

Descriptive statistics serve the purpose of summarizing and organizing data, providing a straightforward overview of the dataset's main characteristics through measures such as mean, median, mode, and standard deviation. They are focused on the data at hand and do not extend beyond it.

In contrast, inferential statistics take this a step further by using sample data to make inferences or generalizations about a larger population. This is achieved through various techniques, such as hypothesis testing, confidence intervals, and regression analysis, allowing researchers to draw conclusions that can be applied beyond the collected sample.

The distinction between these two branches of statistics is crucial for data analysis. Descriptive statistics provide insights into the specific dataset being studied, while inferential statistics enable predictions and decisions based on broader population trends, making the understanding of this difference fundamental to statistical analysis.
