An engineer wants to assess the effect of sintering time on the compressive strength of three different metals. The engineer measures the compressive strength of five specimens of each metal type at each sintering time: 100 minutes, 150 minutes, and 200 minutes.
You can use this data to demonstrate Multi-Vari Chart, Variability Chart, Main Effects Plot, Interaction Plot, and other analyses that use factor and response data.
| Worksheet column | Description | Variable type |
|---|---|---|
| SinterTime | The amount of time a metal is sintered: 100, 150, or 200 | Factor |
| MetalType | The type of metal used in the sample: 1, 2, or 3 | Factor |
| Strength | The compressive strength of each sample | Response |
