Scientists Graph and Analyze the Data Scientists often analyze data for patterns or trends by constructing graphs of the data. The type of graph they construct depends upon the data they collected and what they want to show. A scatter plot is a graph with points plotted to show a possible relationship between two sets of data. A scatter plot has a horizontal xr-axis and a vertical y-axis. The x-axis usually represents the independent variable in the data table. The y-axis usually represents the dependent variable. To show the general relationship between the two variables in the graph, a "line of best fit" is often used. A line of best fit is a line that is drawn to "fit," or come close to, most of the data points.
