Exponential Growth and Logarithmic Scales · Number & Operations

Logarithmic Data Transformation

Using log-log and semi-log graphs to identify relationships in experimental data.

Key Questions

  1. 1Why do we use logarithmic scales to represent data with a massive range of values?
  2. 2How can a curved relationship be transformed into a straight line using logarithms?
  3. 3What do the gradient and intercept of a linearized log-graph represent in the original model?
