logarithmic scale
a scale in which the values of a variable are expressed as logarithms. Such transformations of data are often employed to simplify the drawing of lines on a graph, where the variable values are spread over a wide range. See Fig. 213 . A good example of the use of log scales is seen in Fig. 182 where the LOG PHASE of a microbial GROWTH CURVE is illustrated. Compare LINEAR SCALE.Logarithmic scale
Logarithmic Scale
Logarithmic scale.
On a logarithmic scale or graph, comparable percentage changes in the value of an investment, index, or average appear to be similar. However, the actual underlying change in value may be significantly different.
For example, a stock whose price increases during the year from $25 to $50 a share has the same percentage change as a stock whose price increases from $100 to $200 a share.
On a logarithmic scale, it's irrelevant that the dollar value of the second stock is four times the value of the first.
Similarly, the percentage change in the Dow Jones Industrial Average (DJIA) as it rose from 1,000 to 2,000 is comparable to the percentage change when it moved from 4,000 to 8,000.
