# 1) Based on the graph, students with higher family incomes are more likely to do better on their SAT tests. And students with lower family incomes are more likely to have poorer scores. My first thought is that families with higher incomes might have more money to spare on resources that might better help their children prepare for the SAT. One example would be being able to afford an SAT tutor, whereas families with lower incomes might not be able to afford that extra expense. Another example of how money can affect the child's test score would be the education they are provided with. Perhaps families with more money can afford better education or private education for their children. And not that there is anything wrong with public schools, but not every school does an exceptional job of actually educating the students enrolled. Social stratification is when people in society are grouped based on different factors like income, wealth, race, and power. In this case, wealth is the main factor and we are able to see social stratification based on the student's test scores in different financial situations. Families with the highest income on the graph have drastically higher scores than those on the lowest point of the graph. And I think this shows social stratification because money shouldn't be something that affects student's scores on an exam, and yet it honestly makes a huge difference. One would think that scores would be based upon smarts and brainpower, but it all comes back to money because higher-income families can afford better aid and education for their children. # 2) According to the graph of SAT Scores and Family Income and Distribution of Income and Wealth in the United States, 2011, the students come from the poorest 20% of families whose annual income is below $20,000 are more likely to do poorly on the SATs. Without exception, as family income rises, students' test scores also improve. Even if the subjects are different, the higher the family income is, the higher the student's test score will get. The students come from the richest 5% of families whose annual income is over $200,000 are more likely to do well on the SATs. This shows that family income may affect individual test scores in two ways. One is the increase in the funds that can be invested in education and learning from family income, making students more abundant in learning resources and easier to improve their academic performance. Second, family income affects the family’s lifestyle and indirectly affects students’ learning outcomes. In families with very low incomes, parents may run around and still cannot make ends meet. Naturally, they have no time to accompany and guide their children. It is difficult for children to have a better learning environment from an early age. On the contrary, families with higher incomes have a more stable life, which can even help at least one of parents has more time to take care of the child's study and life, and these factors are more conducive to the child's study. The test scores of students have a direct relationship with their future. According to this trend, their chances of entering a good university, finding a good job, earning a high income and leading a good life also increase with the increase in family income. Therefore, this generation has more than others, and the next generation has a better chance to live better than others, and vice versa. This allows social stratification to be passed down from generation to generation.
