<P> Presentation of data on a logarithmic scale can be helpful when the data: </P> <Ul> <Li> covers a large range of values, since the use of the logarithms of the values rather than the actual values reduces a wide range to a more manageable size; </Li> <Li> may contain exponential laws or power laws, since these will show up as straight lines . </Li> </Ul> <Li> covers a large range of values, since the use of the logarithms of the values rather than the actual values reduces a wide range to a more manageable size; </Li> <Li> may contain exponential laws or power laws, since these will show up as straight lines . </Li>

Why is a logarithmic scale useful in dealing with a large range or variation of some parameter
