How To Read Log Scale

By knowing how to read a logarithmic scale you can more effectively read and represent data in graphic form. Determine whether you are reading a semi-log or log-log graph. Graphs that represent rapidly growing data can use one-log scales or two-log scales.

Learn how to read logarithmic scale, a method to display numerical data that spans a broad range of values. See examples of logarithmic scales in various fields, such as earthquakes, sound, music, and information theory. Lets try to understand log scales a bit better before interpreting this chart with our new-found knowledge: As weve seen last week, log scales are these weird scales where the distance between 0.1 and 1 is as big as the distance between 1 and 10 and 100,000 and 1,000,000.

In this video, I will present a simple and easy-to-follow step-by-step tutorial that will teach you how to read a log graph complete with worked examples. Learn how to plot and read data on logarithmic scales, which represent numbers as powers of 10 or log values. Compare the advantages and disadvantages of different formats and examples of titration curves.

Follow these steps to read a log scale: Step 1: Check if the graph is a semi-log (one axis is logarithmic) or a log-log graph (both axes are logarithmic). Step 2: Look at the major divisions, which are usually based on powers of 10. In a base ten logarithmic scale, 2 cm on the scale corresponds to 10 (100).

3 cm corresponds to 10 (1000). Obviously, if we change the base of the logarithm, the spacing between each number doesn't matter, it is always one cm between each one. A regular graph has numbers spaced at even intervals, while a log scale graph has numbers spaced at uneven intervals.

The reason for this is that while a regular graph uses regular counting numbers like 1,2,3,4, and 5, a logarithmic graph uses powers of 10, such as 10, 100, 1000 and 10,000. Learn what a logarithmic scale is, how it differs from a linear scale, and where its used in everyday life, from earthquake measurements to sound. This page explains how to read, write, and use logarithmic graphs (or logarithmic plots) with examples.
