Unformatted text preview: Geog 165Lg Laboratory Experiment #2 Contour Maps, Isolines, and Areal Measures Wednesday, September 26, 2007, 10:0011:50 Class Number: 35635R Tucker/ Josh Tucker 3108818894 TA: Anthony Questions: 1. The equation for the trend line in my first graph, y= 0.5556x17.778, which is the same equation entered in the graph "C2" to convert the data from Fahrenheit to Celsius. After using the distributive property to solve the conversion equation: 0 T(C) = 5/9 (T(F) 32), = T(C)= 0.5556x17.778. 2. The relationship between maximum and minimum temperature as illustrated in the second of the two graphs is extremely scattered with a very small correlation (r2). The overall slope of this line is m= 0.2996; it is negative, so the overall linear regression trend is downward. This is expected because the overall temperature of the United States is very different, thus the mathematical relationship of minimum and maximum temperature should be very different as demonstrated by the scatter in the scatter plot. 3. The regression coefficient displayed on Graph 1, Maximum Temperature (C) v. Maximum Temperature (F), is basically a straight line. This demonstrates a perfect line and is therefore given a regression coefficient of 1. This is juxtaposed with the scatter of graph two but it is because the relationship between maximum and minimum temperatures will never be related perfectly, because there are so many outside factors and variables. ...
