## Which is a reason for using a log scale for time series data?

A log scale helps if we are comparing changes in two time series of dissimilar magnitude..

## Is logarithmic better than linear?

Logarithmic Price Scale Instead, the measure is plotted in such a way that two equal percent changes are plotted as the same vertical distance on the scale. … Logarithmic price scales are better than linear price scales at showing less severe price increases or decreases.

## What is the difference between linear and logarithmic potentiometer?

With linear potentiometers, the resistance between one end of the track and the wiper varies at a constant rate as the slider is moved along the track. In logarithmic types, the change in resistance is much less at one end of the track to the other.

## What is the difference between logarithmic and linear scale?

Linear graphs are scaled so that equal vertical distances represent the same absolute-dollar-value change. The logarithmic scale reveals percentage changes. … A change from 100 to 200, for example, is presented in the same way as a change from 1,000 to 2,000.

## Why do we use logarithms?

Logarithms count multiplication as steps times more. When dealing with a series of multiplications, logarithms help “count” them, just like addition counts for us when effects are added.

## What does logarithmic increase mean?

A function whose value increases more slowly to infinity than any nonconstant polynomial is said to be a logarithmically increasing function.
