What is the sample mean
An estimate of the population mean (the value you would obtain if you included every organism of the species on the planet)
What is the t-test
Stastically test that allows us to determine whether two means are significantly different
What does a larger A-value indicate
It is more likely that the difference between the 2 means is stastically significant
What does it mean if the t-value is less then the corresponding p-value
The data from out Experiment failed to show any evidence that there is difference between groups, stastically significant does not necessarily mean biologically significant
