NettetA good compromise in science might be to refer to ‘straight lines’ and ‘curves’, though it may be hard to avoid using the term ‘curved line of best fit’. Even though most of the graphs in Figure 7.1 show curves rather than straight lines, they are still all referred to as line graphs. Some relationships in science can be described ... NettetHere's a process you might try. Find the point that is the closest to one corner. Then, find the point that is closest to the opposite corner. Connect those two points. Then, look at the line you draw and compare the rest of the points to it. If there are more points above the line than below it, then you might need to move the line up some.
NettetTo draw the line of best fit, consider the following: Outliers must be ignored. The line must reflect the trend in the data, i.e. it must line up best with the majority of the data, and less with data points that differ from the majority. The line must be balanced, i.e. it should have points above and below the line at both ends of the line.
