Abalone Data Set

Predict the age of Abalone from physical measurements


CC BY-SA 3.0, Link

This beginner level data set has 4177 rows and 9 columns and physical measurements of abalones and the number of rings (representing age). The age of abalone is determined by cutting the shell through the cone, staining it, and counting the number of rings through a microscope -- a boring and time-consuming task. Other measurements, which are easier to obtain, are used to predict the age.

This data set is recommended for learning and practicing your skills in exploratory data analysis, data visualization, and classification modelling techniques. Feel free to explore the data set with multiple supervised and unsupervised learning techniques. The Following data dictionary gives more details on this data set:
