The conclusion that you will be able to reach if method I is used that cannot be concluded if method II is used is that the results can be generalized to the population as a whole.
In method I, the researchers decided to recruit volunteers. This sample includes people who do not exercise, people who exercise alone and people who exercise with a partner. On the other hand, method II will recruit participants at a community fitness center. Therefore, this sample will not include people who do not exercise. This means that method I will have a sample that is more representative of the general population.
Answer: The heat source for Earth’s atmosphere and oceans is the sun, which heats from above instead of below.
Explanation:
In the experiment, the source of heat is the burner below the pot. On Earth this is completely different as the source of the heat on Earth is the Sun which heats us from above instead of below.
The Convection currents still flow in the same direction however because as the sun heats air particles on Earth's surface, they rise but then cool as they keep going up. This makes them go back down where they are then heated up again.
A cognitive psychologist conducts a study to examine differences in cognitive functioning across stages of adulthood. He opts to study one group of young adults ages 21-28. one group of middle-aged adults aged 41-48, and one group of older adults ages 61-
68- The psychologist finding that that the middle age group outperforms the older group is a valid criticism to the study's conclusion
Explanation:
A cognitive psychologist concludes that age relates to cognitive performance on these tasks.This statement means that as a person age's its ability to perform the cognitive task declines .In the study conducted between the various age group the cognitive psychologist where able to find that the people in their middle age (i.e. between 41-48) were able to perform the cognitive task is a better way than the people in the older group. and the younger group was able to perform the cognitive task much better than the middle and the old age group.
Now their is no need for the comparison of the middle age and the old age people for performing the task because as er the conclusion the cognitive skills decline with the age.
So,the psychologist finding that that the middle age group outperforms the older group is a valid criticism to the study's conclusion
