It is practically impossible to test it on every single member of the population. Inferential statistics employ techniques such as hypothesis testing and regression analysis (also discussed later) to determine the likelihood of observed patterns occurring by chance and to estimate population parameters.

How do we link sample spaces and events to data? This means that as the sample size increases, the distribution of the sum or average becomes more tightly clustered around the mean of the distribution, and the shape of the distribution becomes more bell-shaped. One of the most important applications is hypothesis testing. [I

In simple terms, variance captures the degree of “spread-outness” in a dataset—whether the values are clustered closely around the mean or widely dispersed. However, variance offers a clearer mathematical foundation for advanced analyses , such as regression and hypothesis testing. What Does Variance Measure?

Statistics Understand descriptive statistics (mean, median, mode) and inferential statistics (hypothesis testing, confidence intervals). Scikit-learn covers various classification , regression , clustering , and dimensionality reduction algorithms. These concepts help you analyse and interpret data effectively.

Hypothesis Testing : Statistical Models help test hypotheses by analysing relationships between variables. They identify patterns in existing data and use them to predict unknown events. These models help in hypothesis testing and determining the relationships between variables.

Different approaches help organisations make sense of raw data, from simply summarising past events to predicting future outcomes. Clustering: Grouping similar data points to identify segments within the data. Techniques Hypothesis Testing: Determining whether enough evidence supports a specific claim or hypothesis.
