The two types of data involved in quality control are variables and attributes.

- Variables refer to a measurable quantity that can take on different values, such as weight, length, or temperature. These are typically quantitative data and are often used in statistical process control (SPC) to monitor and improve processes. 
- Attributes, on the other hand, refer to a quality or characteristic that a product or service either has or does not have. Examples of attributes include color, shape, texture, or presence of defects. These are typically qualitative data and are often used in acceptance sampling to determine whether a batch or lot of products is acceptable or not.

While assignable and random factors are important concepts in quality control, they are not the two types of data. Random measurements and 100 percent measurements are not common terms in quality control. Accuracy and precision, while related to quality control, are not types of data but rather measures of quality.
