Stepwise Multiple Regression
Often you have a truck load of potential explanatory variables, that all might interact with each other, giving a multitude of potential ways the explanatory variables could relate to the dependent variable. You could painstakingly create every possible model or you could do a step-wise regression. Step-wise regression automatically adds and subtracts variables from your model and […]
The inflammatory nature of microplastics
Plastics are inexpensive, durable, lightweight, versatile material composed of long hydrocarbon chains. These properties have led to widespread use of plastics particularly in single-use packaging. Unfortunately, this has caused a global plastic pollution problem with between 5 and 13 million tonnes of plastic entering our oceans annually. Microplastics are particles of submillimetre plastic. Microplastics have […]

Power Analyses
This is a power analysis for two independent samples compared using a two-tailed t-test and corrected for multiple comparisons using the Holm-Sidak correction. Power calculation is based off Cohen 1988. Cohen J. 1988. Statistical Power Analysis for the Behavioral Sciences. 2nd ed.Hillsdale: Lawrence Erlbaum Associates.
