SOPHIA STATISTICS UNIT 2 MILESTONE FINAL
PAPER 2026 COMPLETE QUESTIONS AND
SOLUTIONS
◉ An experimental design where the assignment of subjects to
treatments is done entirely at random.. Answer:
◉ Confidence Interval. Answer: A range of potential values that the
true value could be. It is obtained by adding and subtracting the
margin of error from sample mean.
◉ Confounding. Answer: Occurs when the effects of the treatments,
if any, are indistinguishable from the potential effects of some other
variable which was unaccounted for.
◉ Confounding Variable. Answer: A variable which was not
accounted for in a study, which limits the conclusions that the study
can draw.
◉ Consumer Price Index. Answer: An index published by the US
Bureau of Labor Statistics that shows the change in the price of
many different goods or services in the United States. It provides a
measure of purchasing power.
, ◉ Continuous Data. Answer: Data that can take any value within an
interval.
◉ Control. Answer: The principle of experimental design that
requires that other variables which may confound the experiment be
held constant between the treatment groups, so that any differences
in the groups can be attributed to the different treatments.
◉ Convenience Sample. Answer: A sample that is easily obtained. It
is often not representative of the population.
◉ Data. Answer: Information used in a study to answer a statistical
question
◉ Deliberate Bias. Answer: The purposeful misrepresentation of
data for the purpose of advancing an agenda.
◉ Double-Blind Experiment. Answer: An experiment where neither
the subjects, nor anyone in contact with them, has any knowledge of
which subjects are receiving which treatment.
◉ Estimate. Answer: The mean value obtained from the sample. If
the sample was well-collected, the estimate should be reasonably
close to the true value.
