1. Graph these data points by hand in your lab notebook. This is graph 1. a. Graphing by hand: i. Use Graph Paper. (Graph paper has gridlines. Your student lab notebook will work.) ii. Draw the x axis. iii. Use the x-axis for the independent variable (the variable that the experimenter controlled; also known as the manipulated variable). iv. Decide on the limits of the axis (maximum and minimum values). The axis does not have to start at zero unless you have data in this region. You may round down from your minimum, but must round up for your maximum. Round to a Chice number. v. Select divisions on the axes which are easy to read. Hence one square may equal 1, 2,
La Mal vi For greatest accuracy, select scales so that the graph nearly fills the page. (At least 5, 10, or 10, 20, 50, 100, but never 3.75 or some other odd number. 2/3 of the page.) vi Label the axis with numbers at appropriate intervals, vi Label the axis with the variable name and the units. For example: Pressure (tom) h Deaw the y-axis. i Use the y-axis for the dependent variable (the variable that the experimenter observed, whose values depended on the independent variable, also known as the responding variable). ii. Decide on the limits of the axis (maximum and minimum values). The axis does no have to start at zero unless you have data in this region. You may round down from your minimum, but must round up for your maximum. Round to a hice Chamber. ii. Select divisions on the axes which are easy to read. Hence one square may equal 1, 2, 5, 10, or 10, 20, 50,100, but never 3.75 or some other loddumber. iv. For greatest accuracy, select scales so that the graph nearly fills the page. (At least 2/3 of the page.). v. Label the axis with numbers at appropriate intervals. vi. Label the axis with the variable name and the units. c. Mark the data points with a small dot. (Pencil may be used before being inked for permanency.) Draw a small circle around the point or darken to make more visible. d. Title the graph in a descriptive manner. For example: (Steve's Pressure vs. Volume e. Using a ruler, draw a straight line that is as close to the data points as possible. The line does not have to start at the origin. A straight line follows the equation y-ms-b 1. Find two points on the line (not specific data points) that exactly cross an intersection point on the graph paper grid. Write down their x, y coordinates. Ideally, these are very far apar on the line. & The slope is (y2-1)/(x2-x) and is m in our equation. The intercept, h, is value ofy where it crosses they axis. h. Write down the equation on the graph, substituting variable names for symbols) for the symbols, x and y. For example, in a graph of mass versus volume, the equation might read Mass-2.5 Volume 002 44
