Activity 1: Graphing The relationship between two or more parameters can be easily visualized by creating a graph. The independent variable is graphed along the x-axis (the horizontal line), and the dependent variable is graphed along the y-axis (the vertical line going up and down). o The two variables you will be graphing today are "Time" and "Mass". Properly indicate which variable goes where on the lines below: y-axis: x-axis: Next, locate your Tables A-3a b from your last lab on "Metric Units of Measurement" to complete the following tables: Colon Polyps: mass (g) Polyp A Polyp B Polyp C Ovarian Tumors: mass (g) Tumor D Tumor E Tumor F You will now use this data to graph your results. Colon Polyps: While polyps can occur is several locations throughout the body (such as the nasal cavities or the uterus), the polyps you examined during the last lab were intestinal polyps taken from a patient who had signs of blood in his feces. Not all patients go to see their doctor immediately when they notice blood in their stools. Using the grid on the next page, properly graph the relationship between polyp mass and time. The polyp mass can be found in the table above, and the time between onset of noticeable bleeding and when he had a colonoscopy to remove his polyps is listed below: Polyp A : 1 month Polyp B: 6 months Polyp C: 12 months First begin by labelling each axis with the correct parameter and proper units based on the information provided above. o Next, assign each box on the x and y-axis a unit of measurement (i.e. 0, 1, 2, etc. grams or months). Be sure to distribute your measurements equally to fill up the entire grid by planning ahead. If your largest mass was "12 grams", then you could label the lines on that axis from 0 to 12 grams. The same would work for time in months
