A hospital observes a rise in hand infections. What steps of the scientific method would you use to address this issue?
Observe the problem, hypothesize about potential solutions (e.g., a new sanitizer), conduct experiments to test the sanitizer, analyze the results, and conclude whether it reduces infections.
You find a claim stating, ‘Eating carrots prevents cancer.’ What steps should you take to evaluate this claim?
Check the source, look for peer-reviewed evidence, evaluate the study design, and investigate potential biases.
Classify the following as logical fallacies or biases: ‘Essential oils cure anxiety,’ ‘Only young, healthy participants were studied.’
Logical fallacy, Bias
Place the steps of the scientific method in the correct order: Analysis, Experiment, Conclusion, Observation, Hypothesis.
Observation, Hypothesis, Experiment, Analysis, Conclusion
What is the difference between randomized controlled trials and anecdotal evidence?
Randomized controlled trials are systematic and scientifically rigorous, while anecdotal evidence is based on personal stories and lacks reliability.
A study claims, ‘New vaccine reduces hospitalizations by 50%,’ but doesn’t mention side effects. What is the flaw?
Framing bias, as it ignores potential negatives.
