There are two main reasons to play with logarithmic bills in charts and you can graphs. The first is to resolve skewness towards the higher viewpoints; we.age., circumstances in which you to definitely otherwise a few affairs are much large compared to majority of the details. The second reason is to exhibit % alter otherwise multiplicative circumstances. Basic I could comment whatever you suggest by logarithms. Then i will provide more detail about all these causes and provide examples.
To refresh the recollections of university mathematics, logs are merely another way out of writing great equations, the one that allows you to separate the latest exponent on one side of your own picture.
