Key Concepts

Data Filtering

Data filtering is the process of selecting a specific subset of data from a larger dataset based on particular criteria. This enables focused analysis on relevant portions of the data, ensuring that the statistical computations or visualizations are performed on appropriate and meaningful groups.

Scatter Plot

A scatter plot is a graphical representation that uses points plotted on a two-dimensional plane to display the relationship between two quantitative variables. It helps in identifying patterns, trends, correlations, and potential outliers by visualizing how one variable may change as the other does.

Correlation

Correlation is a statistical measure that indicates the extent to which two variables fluctuate together. The Pearson correlation coefficient, a common method used for this purpose, quantifies the strength and direction of a linear relationship between variables, with values ranging from -1 to 1.
