WebGraphing data expressed as fold changes, or ratios. Many kinds of experimental results are expressed as a ratio of a response after some treatment compared to that response in control conditions. Plotting ratios can be tricky. The problem is that ratios are inherently asymmetrical. A ratio of 0.5 is logically symmetrical with a ratio of 2.0. WebOct 28, 2024 · Since the numbers are calculated in proportion to the electrical signal, they are relative to the amount of electrical signal produced: the relative in the RLU. Some instruments may use numbers from 0-10,000,000,000 while others may use numbers from 0.1 to 10,000. Moreover, since the PMT relies on electrons to be produced in response to …
