We will share in a discussion of experiments and the role of statistics in analyzing data and drawing conclusions. We will identify guidelines for successful experiments. I will share an example from my work for Dekalb in doing corn research and how statistics had a role in that process.

We will discuss populations and samples today. We will identify different methods for choosing a sample. We will also discuss the size of the sample and randomness.

We will look at terminology related to statistics. We will identify the steps in the statistical process. We will look at ways to produce data. We will compare and contrast experiments and observational studies.

12.2 Surface Areas of Prisms and Cylinders – We learned to apply geometric methods to solve problems. These methods can be used to design an object or structure to satisfy physical constraints or minimize cost. We understand how to work with typographic grid systems based on ratios.
12-3 Surface Areas of Pyramids and Cones – We practiced finding lateral areas and surface areas of pyramids and cones. We learned to use geometric shapes, their measures, and their properties to describe objects.

We studied the measures of center of a set of data, We identified appropriate uses of the mean, median, mode, and midrange. We determined the value of the measures of center for a set of data. We did an example comparing the mean and median for related sets of data.

11.5 Areas of Similar Figures – We practiced finding areas of similar figures by using scale factors. Then we found the scale factors or missing measures given the areas of similar figures. We learned that architecture firms often hire model makers to make scale models and projects that are used to sell their designs. Since the base of a model is geometrically similar to the base of the actual building it represents, their areas are related.
12-2 Surface Areas of Prisms and Cylinders – We practiced finding the lateral areas and surface areas of prisms.

We will study the mean of a set of data. We will review the geometric mean of a set of data. We will also define harmonic mean and do examples of finding all three means.

We will study equations of lines in y= mx + b form and also point-slope form. We will graph parallel lines (same slope) and perpendicular lines (negative reciprocal slopes). Examples will be done and graphs will be drawn using Desmos.

We will review the rule of four for solving problems. We will do an example problem using all four approaches: numerically, verbally, symbolically, and graphically. The basic concept is to know all four methods so that the best one can be chosen in a given situation.

We will write square roots using the exponent 1/2. We will solve linear equations using the rule of four. Examples will be done in class.
