question 3
standard: fl.20.best.ela.k12.ee.3.1
passage: \video games cause violence in teenagers,\ claims dr. smith, but his study
only surveyed 20 students from one school, all of whom were already known for
behavioral problems. meanwhile, comprehensive studies involving thousands of
participants from multiple countries show no causal link between gaming and
aggression.
what makes dr. smiths argument weak?
his sample size is too small and biased
he provides too much evidence
he uses too many participants
his argument is too strong

Explanation:

Dr. Smith's study only surveyed 20 students from one school. A small sample size (20 is small) and from a single school (biasing the sample as it's not representative of a larger population like teenagers in general) weakens the argument. Comprehensive studies with thousands of participants from multiple countries show no causal link, contrasting with his small - sample approach.

Answer:

His sample size is too small and biased.
