PLP_7 T-test Example 2: Separate Variance
Furness and Bryant (1996) measured the metabolic rates of eight male and six female breeding northern fulmars and were interested in testing the null hypothesis that there was no difference in metabolic rate between the sexes (Box 3.2 of Quinn and Keough(2002)). To start this activity, I reset first the R’s memory using the code below: rm(list=...

PLP_10 Simple linear regression
Linear regression models are used to show or predict the relationship between two variables or factors which are the dependent variable and independent variable. Simple Linear Regression Analysis is the simplest form of regression analysis which uses one dependent variable and independent variable, and a straight line approximates the reltionship...
