Aluminum properties data

An engineer at an aluminum castings plant assesses the relationship between the hydrogen content and the porosity of aluminum alloy castings. The engineer collects a random sample of 14 castings and measures the following properties of each casting: hydrogen content, porosity, and strength.

You can use this data to demonstrate Correlation, Covariance, and other analyses that explore the relationship between three measurement variables.

Worksheet column Description
hydrogen The hydrogen content measurement of the sample
Porosity The porosity measurement of the sample
Strength The strength measurement of the sample
