Biostatistics — Flashcards

Measurements that are widely scattered (poor reproducibility) but have a mean value close to the true value represent _____ precision and high accuracy.

Exclusion criteria can result in _____ being compromised if too strict, maximizing Internal Validity

_____ is decreased by random error in a test

The chi-square test can be used to evaluate whether the _____ frequency of an occurrence is consistent with the observed frequency of that occurrence

Converting Probability (P) to Odds (O), O = (_____)/(1-P)

When measurements are both tightly clustered together (consistent) and close to the true value, this represents _____ precision and high accuracy.

Meta-analyses are limited by: - _____ of individual studies - Bias in study selection

When raising the cutoff point for a disease, the _____ and NPV will decrease

_____ is also called as post-test probability of a disease/ precision rate

Bimodality usually indicates that the study material _____ homogenous, and two causative factors might be in effect
