Electrophysiological Recording of Conduction Velocity and Sensory

Electrophysiological Recording of Conduction Velocity and Sensory The results section is important It is often where a researcher starts reading Used to summarize the data ex. Tables, figures, short written responses There is an analysis of the data (statistical analysis) In the results section there is no interpretation of the data; however the reader can make their own interpretation o This interpretation Write a results section o Scenario: o Imagine you are a researcher that has collected conduction velocity (metres·sec-1) data from 6 cockroach (Periplaneta americana) sensory neurons at varying temperatures to submit to a scientific journal. You obtained the following raw data: o o o o o

Using the data in Table 1, you decide to run a one-way repeated measures analysis of variance (ANOVA) to test whether or not the means of several groups (Temperatures 0 – 25°C) are different. You choose a repeated measures analysis since each cockroach leg was stimulated at multiple temperatures. You perform the appropriate statistical analysis and find that there is a significant difference in the conduction velocity with each 5°C increase in temperature (F = 57.7; d.f. = 35; P
