Yaxn Log Graph. If y ab x then log y log a xlogb. The transformation of the data set from y vs.
In each case a straight line is obtained of slope n log 10 y 2 log 10 y 1 log 10 x 2 log 10 x 1. X to Y logy vs. If y Ax n then the log-log plot is the graph of the straight line log y n log x log A So if the slope is the same the power n is the same in each case.
If we plot a graph of logy vs log x.
We take the logarithm of the data values in both columns of the data set to discover the power trend. X logx is called a log-log transformation. In each case a straight line is obtained of slope n log 10 y 2 log 10 y 1 log 10 x 2 log 10 x 1. In a log-log graph both the x-axis and the y-axis are logarithmic.
