+ +## Concrete Compressive Strength Data Set + +### Estimate compressive strength of concrete + + +--- +![](123.jpg) +--- + +This *intermediate* level data set has 1030 rows and 9 columns. +Concrete is the most important material in civil engineering. The concrete compressive strength is a highly nonlinear function of age and ingredients +The actual concrete compressive strength (MPa) for a given mixture under a specific age (days) was determined from laboratory. Data is in raw form (not scaled). + +This data set is recommended for learning and practicing your skills in **exploratory data analysis**, **data visualization**, and **regression modelling techniques**. +It also allows you to practice with non-linear functions. Feel free to explore the data set with multiple **supervised** and **unsupervised** learning techniques.
