Specify the number of clusters to be created (this is done by the data scientist). Taking the flowers example from the previous unit, this means deciding how many clusters you want to use to group the flowers. The algorithm randomly selectsKobservations from the dataset to serve...
Each centroid is moved to the center of the data points assigned to it based on the mean distance between the points. After the centroid is moved, the data points may now be closer to a different centroid, so the data points are reassigned to clusters based on the new closest cent...

The scatter plot is the renegade artist of the data world, throwing dots across a grid to show us the relationship between two variables. Where the dots fall, a story is told, revealing correlations or intriguing clusters. What to use it for: Spotting correlations between variables Identifying...
Atrial fibrillation (AF) is the most common sustained arrhythmia in clinical practice. Inflammation plays an important role in the initiation and perpetuation of AF. The present study was conducted to characterize immune clusters in nonparoxysmal AF and

scatter plots can be useful for viewing relationships between data across multiple variables. Scatter plots can highlight trends, clusters, patterns, and relationships between numeric data. For example, you could create a scatter plot to report on whether or not providing a larger discount leads to...
