Although exposure to graphs and the rhetoric used to describe the findings that social scientists use to describe the results of their studies are well-known the individual elements are not as familiar to the general public. The first chapter powerpoint presentation describes each of these elements and relates how each element is incorporated into the final result. The chapter does a good job of explaining the purpose behind research and how the methods used to accumulate the data are important to the final product.

Chapter Two

In the second chapter it is explained how the individual techniques described in Chapter One are incorporated in order to produce the final product. The use and design of the different types of graphs is clearly set forth and the purposes behind the use of tables and graphs are defined. The method of interpreting graphs and their related tables is also explained.

In Table 5 the two variables are education level and population size.

In our reading assignments and the accompanying powerpoint presentations the examples were demonstrated using only one variable. This allowed one to see a direction correlation between any changes in the variable and the results. When an additional variable is added, it requires that one examine the effect of the variables more closely. For example, in Table 5 education….....
