Question 1

As adults age, their physical strength declines. What type of correlation exists between age and physical strength?

a strong correlation
a negative correlation
a weak correlation
a positive correlation

Question 2

As part of a study examining the role of different teaching methods on children's math abilities, Dr. Garneau tested the children using a standardized math test. In Year 1, the standard teaching method was used. In Year 2, a new teaching method was used. In Year 1, the test was administered in October, near the beginning of the school year. In Year 2, the test was administered in May, near the end of the school year. Although Dr. Garneau's results suggest that children in Year 2 demonstrated more math skills than children in Year 1, why are Dr. Garneau's results not very useful?

There was no control group.
Results due to teaching method are confounded by the time of year the children were tested.
Children in Year 2 had the benefit of a different teaching method, so you can't compare them to children in Year 1.
Different children were used in each group, and this is a confound.
