Key Concepts

Sampling Bias

This concept refers to a bias that occurs when the method used to select participants (in this case, jurors) systematically excludes certain segments of the population. When juror lists are compiled solely from voter registration and DMV records, groups that are less likely or unable to register to vote or obtain a driver's license may be underrepresented, leading to an unrepresentative sample of the community.

Undercoverage

Undercoverage happens when certain parts of the population are not adequately represented in the sampling frame. For juror selection, sectors such as non-registered citizens, economically disadvantaged individuals, younger populations, immigrants, and those who do not own or drive vehicles might be omitted, thereby distorting the cross-section of the community that is supposed to be reflected in the jury pool.

Demographic Representativeness

This concept involves ensuring that the demographic characteristics of a selected group, like a jury pool, accurately reflect those of the overall community. Using only voter rolls and DMV records can lead to a jury that does not mirror the community's diversity, potentially affecting the fairness and impartiality of trials.
