Market basket analysis (also called association analysis) is one of the most important methods used to uncover relationships between items. It looks for combinations of items that frequently occur together in transactions. In other words, it enables retailers to identify relationships between the items that customers buy.
Market Basket Analysis is part of data mining and explained how to find Frequent Item set using Association Rule Mining. We will discuss SUPPORT, CONFIDENCE and LIFT

A Raincloud Plot is a data visualization tool that provides a comprehensive view of a dataset by combining several plots into one figure. It essentially brings together the power of a box plot, violin plot, and a strip or swarm plot, making it easier to understand both the overall distribution and the raw data of a given variable or group.
But what are the components of a Raincloud Plot?
Cloud (Violin Plot):
The cloud in the Raincloud Plot is a rotated and horizontally aligned kernel density estimation (similar to a violin plot) that shows the distribution density of the data. It provides insights into the shape of the data distribution, highlighting areas of higher density.
Rain (Strip or Swarm Plot):
The rain consists of individual data points or raw data, represented as dots. This part of the plot shows each data point, giving a clear view of the raw data.
Boxplot:
Often theres a traditional box plot, showing the median and interquartile range.

What is a Pearson correlation? The Pearson correlation analyses the linear relationship between two variables. With the help of the Pearson correlation coefficient r which is between -1 and 1 we can determine:
How strong the correlation is
and in which direction the correlation goes.
