PROJECT INTRODUCTION
Inheriting (Im)Possibility is Ezekiel Dixon-Roman’s study on quantitative and qualitative data and how they affect an individual’s knowledge of an engagement with the world. His study involves multiple models that focus on specific relationships between different variables. The first model presented to us focused on education, wealth, and ethnicity and how they directly and indirectly affect each other. The first group of data consists of quantitative elements, such as wealth and education. Quantitative data represents variables that can be measured numerically. Alternatively, the qualitative data consists of parent/child relationship and ethnic background. Qualitative data is described as information that can be observed but not measured. In the case of both qualitative and quantitative variables, each can affect other variables that are within or outside of their own group.

FIRST TABLES
The first set of data we received was intensive quantitative charts displaying all of the variables being studied. The next set of five figures within the first model was processed into vertical bar graphs by Microsoft Excel. Our challenge was to fully interpret these graphs that were missing key relationships and pieces of data that refer back to the original charts.

Figure 3 is used to express the differences in median wealth holdings between ethnicities. These holdings display net worth, total illiquid assests, total liquid assets, and total debt that are measured in monetary values.

Figure 4 represents the ethnic differences in SAT performances through unconditioned and full structural models. Unconditioned focuses exclusively on the child’s education while the full structural model includes all other factors such as assets.

FIGURE 5
Figure 5 displays how the SAT score differences affect the median wealth holdings of racial groups. The graph shows that when there is a decrease in wealth within the groups, the SAT scores decrease as well.

FIgure 6: Paternal grandparent education SAT ffects
FIGURE 5
Figure 6 is the focal point of the model. Since figure 6 shows the direct and indirect effects of paternal grandparent education on SAT performance, it embodies the overall concept of the model while the other graphs support it. The direct effect is the effect using only the grandparent’s level of education while the total effect accounts for the grandparent’s education along with all other assets (wealth and race).
PROJECT INTRODUCTION
When beginning the redesign process of the graphs, as a group we decided to edit the information so that it would be easily relatable throughout the model. Changing graph titles and variable wording created relationships between variables within the model. Adding definitions for variables also helps the reader thoroughly understand the concept of each graph individually and the model as a whole. Towards the end of the process, after understanding and working with the model, we rearranged and renumberd the order of the graphs so that the connections would build on each other. Another design choice we made was to add negative values to graphs that dealt with integers below zero and condensing or separating graphs so that each figure would be displayed with its contextual content. Each change we made to the model was to make the concept more easily interpretable.

FIGURE 2 REVISED
Through the design process, we found that Figure 2 would be most successful if the wealth holdings could be represented with positive and negative values. Our solution was to create a vertical graph that contained bars rising above and below the baseline of zero. Total liquid assets, plus total illiquid assets, minus debt results in net worth. In organizing the variables this way the reader can understand the connections between wealth assets. Grouping ethnicities with their own wealth numbers, makes the differences in wealth more obvious.

FIGURE 3 REVISED
Figure 3 portrays the effect of wealth on SAT scores amongst the different racial groups. When we reexamined the data, we found that the numbers were too close together to emphasize the resulting difference in a bar graph. We decided that the best way to proceed would be to translate the data into percentages. By using percentages and reorganizing the data, we could present the differences in numbers with greater effect.

FIGURE 4 REVISED
The SAT scores for Figure 4 proved to be difficult to design. Being so close together, many graphs and charts did not emphasize the difference in scores between Black and Hispanic ethnicities within the unconditioned and full structural models. After working with a point and line graph for a period of time, we came to the conclusion that separating the unconditioned and full structural models would be the best option. The bars, from left to right, measure a quantity. Using true SAT scores that start at 400 (the lowest SAT score possible), each bar extends to the achieved SAT score on a scale that caps at 1600.

FIGURE 5 REVISED
In Figure 5, direct and total effect needed to be displayed in a way that showed the positive correlation between paternal grandparent education and grandchildren’s SAT scores. Instead of using a bar graph that is static and evenly spaced, we chose to design a line graph that showed the rise in education and SAT scores as a steady incline. We also chose to represent the scores in true SAT score form. Doing so helps the reader to fully understand the context of the numbers. Data for Figure 5 is still being tested, and therefore may redetermine the state of the final graph.

CONCLUSION In order to complete designing model one, we will need to rework and fine tune some aspects of each figure. We would also like to consider creating color versions, to give the publisher variety. As we finish up with the current model, we will begin to discuss continuing onto other models after the course ends. We will be able to take the skills and techniques we have learned from designing the first model and apply them to the upcoming models in a concise, relative way.
