Two polls of an upcoming election are conducted. One questions 100 people, the other
questions 500 people. Which is more likely to have accurate results? Why? - Correct
Answers -The 500-person poll. Because it has a higher sample size, there is less likely
to be results influenced by random sampling errors.
Give an example of qualitative and quantitative data that could be collected from an
experiment. - Correct Answers -Quantitative data includes numerical measurements like
mass, volume, temperature, etc. Qualitative data is based on descriptive observations
like color, smell, behaviors, etc.
Explain how a double-blind experiment would help to minimize bias in a drug study. -
Correct Answers -A double-blind experiment prevents both the experimenter and
subjects from knowing who is the control and who is the experimental result. This
prevents bias on the part of the subjects (placebo effect) and bias from the researchers
as they perform their measurements.
