In single-case experiments, increasing the number of measurement points:
A) makes it more difficult to identify precipitating conditions during assessment.
B) makes it harder to change the intervention plan at the point at which no progress is occurring.
C) increases our ability to pinpoint unlikely coincidences and therefore infer what is causing changes in the dependent variable.
D) lessens internal validity.

Increasing the number of measurement points in single-case experiments allows for a more thorough analysis of the data, potentially identifying unlikely coincidences and aiding in inferring the cause of changes in the dependent variable. It does not necessarily make it more difficult to identify precipitating conditions during assessment or make it harder to change the intervention plan at the point of no progress. However, increasing measurement points may slightly lessen internal validity by increasing reactivity and demand characteristics.
