Answer:
Hmm there are many things such as demographic transitional models, and epidemiological transition models, population pyramids, etc.
Explanation:
the models and population pyramids both help someone learn about an area at a given time. We can see how developed a country is by looking at birth and death rates, gender ratios, etc. For example, less children and a longer life expectancy means a more developed country, seeing as people live longer so there is no need for all those kids, and women are being given more education so it is less likely for them to want to stay home, but rather go out and get an education (:

Lighting significantly affects performance
Explanation:
In this study, Ellen took two groups and applied the same IQ test to both of them. The only variable that changed between the groups was the level of lighting in the room. The first group was placed in a room with very bright lights and the second group was placed in a room with more normal lighting.
Individuals in the first group did better in the IQ test and she found that the difference between the two scores was statistically significant.
We say that a result is <u>"statistically significant" when it is not likely to occur randomly but rather is likely to be attributable to a specific cause.</u>
<u />
So we can say that <u>the better performance in the first group tests were not likely to occur randomly but it can be attributable to a specific cause. </u>
<u></u>
<u>Since the only variable that was different between the groups was the lightning, we can conclude that lighting significantly affects performance. </u>
Political factions or parties began to form during the struggle over ratification of the federal Constitution of 1787. Friction between them increased as attention shifted from the creation of a new federal government to the question of how powerful that federal government would be.
