C) shape.
D) specification.

Range is a measure of how much the observations in a process distribution vary or spread out from each other. The greater the range, the higher the dispersion or variability in the process. Therefore, range is a good indicator of the consistency and quality of a process, and can help identify potential problems or sources of variation that need to be addressed. Average (A) is a central tendency measure that reflects the typical value of a data set, but it doesn't say anything about how spread out or diverse the data points are. Shape (C) is a descriptive characteristic of a distribution that refers to its form, such as symmetric, skewed, or bimodal, but it doesn't quantify the amount of variability in the values. Specification (D) refers to the target or acceptable range of values that a process must meet to achieve its objectives, but it doesn't imply anything about the variability of the actual performance.
