Increased precision in the analysis can be achieved by?
A)Assuming measurements taken from the same participant correlate,so to test for a difference in treatments involves smaller error variance.
B)Increasing the risk of human error at data entry stage.
C)Testing every data set numerous times until the desired result is achieved.
D)Ignoring errors.

Question

Quizplus · Accepted Answer

Assuming measurements taken from the same participant correlate allows for a more precise analysis because it acknowledges the inherent relationship between repeated measures on the same individual, leading to a reduction in error variance. This approach leverages within-subject variability to enhance statistical power and precision.
