(1.5 points) Why would these data be described as bivariate? The data are bivariate because they comprise sets for two different variables. What is the explanatory variable (independent variable, x)? Length is the explanantory variable What is the response variable (dependent variable, y)? Weigth is the response variables Part B. Use your responses in Part A to write the puppy data as 10 ordered pairs (x, y). (2.5 points) (40,7.2),(7,1.3),(33,9),(24,5.8),(14,2.5),(48,9.7),(9,2.3),(18,1.6),(13,1.8),(21,2.9) Part C. Use your ordered pairs from Part B to display the puppy data on the scatterplot below. (5 points)Student receives 0.5 point correctly plotting each ordered pair,for a maximum of 5 points. Part D. Use the scatterplot from Part C to answer these questions. (2 points) What kind of correlation exists between the length and weight of the puppies? Explain. There is a positive correlation exists between the variables, because as the explanatory variable (Length) increases, the response variable (Weigth) increases. Does this correlation imply causation? Explain. It seems to imply causation, since it is logical that the...

...Diagnostic Algebra Assessment Definitions Categories Equality Symbol Misconception Graphing Misconception Definition Concept of a Variable Misconception Equality Symbol Misconception As algebra teachers, we all know how frustrating it can be to teach a particular concept and to have a percentage of our students not get it. We try different approaches and activities but to no avail. These students just do not seem to grasp the concept. Often, we blame the students for not trying hard enough. Worse yet, others blame us for not teaching students well enough. Students often learn the equality symbol misconception when they begin learning mathematics. Rather than understanding that the equal sign indicates equivalence between the expressions on the left side and the right side of an equation, students interpret the equal sign as meaning “do something” or the sign before the answer. This problem is exacerbated by many adults solving problems in the following way: 5 × 4 + 3 = ? 5 × 4 = 20 + 3 = 23 Students may also have difficulty understanding statements like 7 = 3 + 4 or 5 = 5, since these do not involve a problem on the left and an answer on the right. Falkner presented the following problem to 6th grade classes: 8 + 4 = [] + 5 All 145 students gave the answer of 12 or 17. It can be assumed that students got 12 since 8 + 4 = 12. The 17 may be from those who continued the problem: 12 + 5 = 17. Students with this misconception may also have difficulty with the idea that adding...

...Example 2.1 with Pie Chart - Graphing and Summarizing Qualitative Data A group of cardiac physicians in southwest Florida have been studying a new drug designed to reduce blood loss in coronary artery bypass operations. Blood loss data for 114 coronary artery bypass patients (some who received a dosage of the drug and others who did not) are saved in the BLOODLOSS file. Although the drug shows promise in reducing blood loss, the physicians are concerned about possible side effects and complications. So their data set includes not only the qualitative variable, DRUG, which indicates whether or not the patient received the drug, but also the qualitative variable, COMP, which specifies the type (if any) of complication experienced by the patient. The four values of COMP recorded by the physicians are (1) redo surgery, (2) post- op infection, (3) both, or (4) none. Figure 2.5, generated using SPSS, shows summary tables for the two qualitative variables, DRUG and COMP. Interpret the results. Interpret the Minitab output shown in Figure 2.6 and the SPSS output shown in Figure 2.7. This tutorial will demonstrate how to use Minitab to reproduce Figures 2.5, 2.6 and 2.7 on page 36 of the textbook.

...Linear Functions Unit Plan Part 2 – EDCI 556 – Week 2 Darrell Dunnas Concordia University, Portland Linear Functions Unit Plan Part 2 Mr. Dunnas decides to change the graphing linear equations lesson into a problem-based lesson. This lesson is comprised of three components. Component number one is to write the equation in slope-intercept form (solve for y). Component number two is to find solutions (points) to graph via t-tables and slope-intercept form. Component number three is to graph the equation (connect the points that form a straight line). In mastering this lesson, all components must be addressed. In teaching, all learners how to graph linear equations, one must create a meaningful context for learning. First, the lesson must be aligned to the curriculum framework (Van de Walle, Karp, & Bay-Williams, 2013). Graphing linear equations is a concept found in the curriculum framework. Second, the lesson must address the needs of all students (Van de Walle, Karp, & Bay-Williams, 2013). The think-aloud strategy and graphing calculators will be used to graph linear equations and address the learning styles of all learners. Third, activities or tasks must be designed, selected, or adapted for instructional purposes (Van de Walle, Karp, & Bay-Williams, 2013). Lectures, handouts, videos, and cooperative learning activities will be used in teaching the lesson. Fourth, assessments must be designed to evaluate the lesson...

..." Using Spreadsheets and Graphing • in Excel In this case the independent quantity is Concentration and the dependent variable is Signal (we know the concentration, but we have to measure the signal that it causes). This means that Concentration should be on the X-axis and Signal should be on the Y-axis. In Excel, the X-axis values need to be to the left of the Y-axis values. Procedure 1: Basic Spreadsheet Entry 1. Open MS Excel on your computer. It will help to maximize the window so it fills up the screen. Your instructor will lead you through the steps in the following exercise. Follow along on the instructions as well as listening closely to your instructor and following directions.

...Describe how you conducted the experiment. What variables did you investigate in this experiment? We had one person hold the meter stick up perpendicular to the floor and drop the bouncy ball provided ball with no force, straight down from the height of our choosing. We chose the heights 100cm, 90cm, 80cm, 70cm, 60cm, 40cm, and 20cm. The remaining members of our group watched to see how much it would bounce up, we did 3 recordings of the bounce height for each drop height and averaged them by using the obvious equation where you add them all up and divide by how many there are. We rounded to whole numbers because it is too hard to have a fraction of a centimeter because they’re already too small. We recorded the data on the assigned. I used drop height as my x and the average bounce height as my y. Make a scatter plot of the data you collected on graph paper.

Take 1 hanging weight off the cart and attach it to the end of the string on the cart with the other hanging weights still on top. 3. Place the cart on the ramp in front of the motion detector. 4. Set the GLX using the correct units for the y and x axis for graphing. Then measure 20cm away from the motion detector, place the cart there and start the GLX and release the cart from 20cm at the same time. Stop the GLX and the cart few centimeters before the cart reaches to the end of the ramp for precise data. 5. Repeat steps 2, 3 and 4 by adding 1 hanging weight to the string of the cart with the previous hanging weight already on the string until all hanging weights are used and not left on top of the cart. Then record data. Experiment 2: 1. Weigh the hanging weight and record the mass (this will be left constant for all trials). 2. Add a metal cube on to the top of the cart and weigh and record the mass of the cart with metal cube. Then place the cart on the ramp in front of the motion detector. 3.
