From sample to population – Hypothesis Testing
The relationship between sample and population is key in statistics. Samples allow researchers to estimate population characteristics without studying everyone. Variations between samples, called sampling variability, are natural but can be managed using concepts like the Central Limit Theorem, enabling accurate inferences about populations.

Statistical inference helps us make sense of data and draw conclusions about larger groups by analyzing smaller samples. It uses descriptive and inferential methods to find patterns, test ideas, and predict outcomes. Probability plays a key role by helping us handle uncertainty and make better decisions based on data.
