Driving Data Worksheet Use the graphs and charts to answer the questions about the data presented. GRAPH ONE 1. In the first part of the study, you gave four volunteers tracking devices to see how far and how fast they drove on their daily commute. Use Graph One to answer each of the following questions and give a brief explanation for each answer. a. What are the dependent and independent variables? The dependent variables on the graphs are on the Y-axis listed as \"Distance from home (miles) and the independent variables on the graphs are on the X- axis listed as \"time (minutes.) The time influences the distance from home. b. Two of your participants told you that they had problems come up during the studyone got a flat tire, and the other had to turn around and go home to pick up something she forgot. Which participants had these issues? Participant A had traveled 4 miles from her home within 20 minutes but then returned home at 40 minutes where the distance from home became (0) Participant D traveled 15 miles from her home within 25 minutes but remained 15 miles away from her home for about 50 minutes (this is the time she was not moving due to her flat tire) c. Describe the driving behavior of the other two participants based on the shape of the graph. When were they speeding up, slowing down or driving at a steady speed? Participant B had a steady speed from 0 minutes to 25 minutes at which her speed increased gradually, until around 65 minutes at which point her speed increased again and remained steady until the end of the study. Participant C had a slow increase in speed from 0 minutes to about 50 minutes at which point the participants speed increased again and continued at a stead speed until around minute mark 75 where the speed increased again until the end of the study. d. On what kind of road was Participant C likely driving between minute 50 and minute 80? How can you tell? Participant C was likely driving on a highway between minute 50 and 80 because the participants speed and distance from home had a large incline. CHART ONE 2. In the second part of the study, you surveyed 580 drivers and asked about their daily commutes. Use the information in Chart One to answer the following questions about the average distance people drive each day. a. About how many people commute between 11 and 40 miles each day? 189 people commute between 11 and 40 miles. 51 (11-20 commuters) +60 (21-30 commuters) +78 (31-40 commuters) b. About how many more people commute 41-50 miles than drive 61-70 miles? About 14 more commuters travel 41-50 miles than 61-70 miles. 90 (41-50 commuters)-76 (61-70 commuters) = 14 c. About how many people commute more than 70 miles per day? About 102 people commute more than 70 miles per day 46 (71-80 commuters) +32 (81-90 commuters) +14 (91-100 commuters)+10 (more than 100 commuters)= 102 CHART TWO Note: All data are hypothetical. 3. In the final part of the study, you compared the types of cars people own. Examine Chart 2 to answer the following questions. a. What percentage of drivers own compact cars? 12% of drivers own Compact Cars 1%+4%+10%+9%+8%+19%+3%+2%+32%=88% 88%-100%=12% b. What is the second least popular type of car owned? Coupe, only 2 percent of people own coupes. c. Which two kinds of cars, together, make up over 50% of all cars owned? The sedan at 32% and the Station Wagon at 19%= 52% d. Together, the four least popular kinds of cars make up what percentage of all cars owned? Other 1%+ (Pick-up truck) 4% + (Coupe) 2%+ (Convertible) 3% =10%
