A. In a business cycle there are ups and downs. When there is a peak or a high business is booming and employment is high, unemployment is down and inflation is high.
B. We have to bear in mind that there are four kinds of unemployment: structural, frictional, cyclical and seasonal. Structural unemployment is caused by the type of production and rules of an economy that govern whose abilities are valued in the market so it is not so realated to the business cycle. frictional unemployment is linked with changing jobs ( workers are moving or searching for better opportunities) so this is not so related to the business cycle. Cyclical unemployment is related to the change in the GDP (Gross Domestic Product) so<u> it is related to the business cycle</u>, Seasonal employment is associated with changes in the season so it is no so related to the business cycle.
Answer:
Part A:
The cofounding variable is a factor that could cause a result on the experiment. This would be the people taking extra food.
Independent variable would be being asked to sign in or not and take free food, because independent variable is a variable that is changed or manipulated and in this case the people were split in half and the hypothesis is that the people who didn't sign in would take more food.
Operational definitions are important when conducting research because it defines all the variables in the experiment, so it can be replicated. The operational def for the dependent variable would be "Doing the right thing even though you aren't being watched"
Part B:
The data does not support the hypothesis because even the people who signed in could've taken extra food when the dean wasn't looking. The findings cannot be generalized to all students because some students could have been taught better and can differentiate between right and wrong. So the people who were not signed in could've just taken one burger and drink, and the people who were signed in might feel obligated to take more than one burger because they had signed in and didn't just come without signing in.
The study is not a naturalistic observation because the observer did not look at the people who took the food and which side took more food.
The reinforcement of Successive Approximations is used in a broad sense of Skinnerian Operant Conditioning
Answer:
1. It reduces the probability of sampling bias.
2. A random sample will be more representative of the whole population.
3. Allows the researcher to determine the efficacy of the fertilizer.
Explanation:
Selecting a simple random simple from a large population is a widely used method in science. Researchers select a random sample so every individual, in this case seedling, has an equal chance to be selected.
Therefore, it is an accurate method that, although is not free from errors, avoids or reduces the probability of sampling bias. Selecting a truly random tomato seedling will be more representative of the whole population of seedling instead of selecting carefully a seedling that already has specific or desired characteristics. Hence, this random sampling will allow the researcher to determine the efficacy of the fertilizer.
