**Name**: Water
Purification Systems

**Abstract**: In
addition to the measuring of pH values of water samples, the study of water
purification systems can be measured with other variables to determine the
water’s purity.

**Variables (column)**:

- Type of filtration system (0=Deionizing, 1=Ultra-Pure)
- pH value
- Conductivity (siemans/cm)
- TAMP (total aerobic microbial population in terms of the number of colony-forming units per 100ml)
- TOC (total organic carbon in parts per billion)

**Possible Uses**: Correlation,
General Linear Model, Independent Sample T Test
