Inquiry 4.1
Suggestions for
Making a Graph
- Give each graph a title that describes the data being displayed.
- Cover as much space in the graph as possible with plotted data. Leave enough space along the axes for labels, even-scale divisions, and units of measure.
- Label horizontal and vertical axes with a description of the data being plotted and the units of measure.
- Plot the independent variable (the data being controlled) on the horizontal, or x axis, and the dependent variable on the vertical, or y axis.
- Set the scale for each axis with even divisions, letting the highest measured value in the data fit on the axis.
- Make sure all spaces on the x and y axis scales are equal, even if they are not marked in the same intervals.
- Make scaling of the axes start from zero at the intersection of the axes (called the origin) and increase in value, moving right on the x axis and upward on the y axis.
- Plot the location of each data point on the graph with a small dot.
- To account for some natural variability in data values, place small circles around the data to make it easier to join points with smooth curves.
Construct a graph
using the class average data you recorded in Table 4.1 and Table 4.2.
