Key Concepts

Descriptive Statistics

Descriptive statistics involves summarizing, organizing, and presenting data that has been directly observed or collected. This branch of statistics deals with methods for quantitatively describing the main features of a data set and summarizing it in terms like mean, percentage, or standard deviation without making predictions or extending conclusions beyond the data at hand.

Inferential Statistics

Inferential statistics is concerned with drawing conclusions and making predictions or generalizations about a larger population based on a sample of data. It uses methods such as estimation, hypothesis testing, and confidence intervals to infer trends, patterns, or characteristics in the whole population, even though only a subset of the data is directly observed.

Population vs. Sample

The concept of population versus sample is central to statistics, where a population represents the entire group of interest, and a sample is a smaller, manageable subset of that group. Descriptive statistics often describe the sample data directly collected, while inferential statistics use the sample to make generalizations or predictions about the entire population.
