Parametric and non-parametric tests: If you want to calculate a hypothesis test, you must first check the prerequisites of the hypothesis test. A very common requirement is that the data used must be subject to some distribution, usually the normal distribution. If your data are normally distributed, parametric tests can usually be used, if they are not normally distributed, non-parametric tests are usually used.

What do you need the Fleiss Kappa for? In general, you use the Fleiss Kappa whenever you want to assess the agreement between more than two raters. In the case of Fleiss kappa, the variable to be measured by the raters is a nominal variable. Therefore, if you have a nominal variable, you use the Fleiss Kappa.
The Fleiss Kappa is a measure of the agreement between more than two dependent categorical samples.

What is a Bland-Altman Plot? The Bland-Altman plot is a graphical method to compare two measurements. In essence, a Bland-Altman plot is a scatter plot where the differences between two measurements are plotted against their averages. This helps to visualize the degree of agreement between the two raters and identify any systematic bias.

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.
