## Cameron M. Rehmani Seraji Reflection Questions

1. The main take-home message of this paper is it is necessary to provide a framework adaptable to any STEM discipline that will encourage communication between mathematicians, statisticians, and biologists. Creating a universal understanding and approach to modeling will allow professionals to close the gaps between the disciplines. The "rule of five" will allow the STEM fields to work together more efficiently and effectively.
2. Since the in-class "cell" exercise, my understanding of what a model is has changed. At first, I thought that modeling was small scale replications of situations and required mathematics to see any results. However, I now know that modeling has many more applications than I originally thought. Modeling can be categorized into five types: Experiential, Numerical, Symbolic, Verbal, and Visual. Experiential, for example, is based of direct experiences that are concrete rather than abstract ideas. The results from this type of model are based off experiments and observations to make conclusions. This is one thing that I had never considered to be modeling.
3. Yes, I was engaged in modeling this week while I was making the different plots on the Matlab program. We were provided with data, we then plotted the data on graphs, and then we analyzed the graphs to make a conclusion about the relationship between the data. The specific type of data that we analyzed this week were logistic growth curves which told us the relationship between the number of people in a population and the growth rate of that population. We transferred this real world data into Matlab and so observations and conclusions could be made. This makes up the modeling process.
4. One thing that I found confusing from the article is difference between numerical model representations and visual model representations. I think I understand it as the numerical model of representation is the data that was observed and found during the modeling process while the visual model of representation shows the data presented in tables and figures clearly so the reader can understand the results.
