The Analysis of Biological Data (3rd Edition, 2020) –
Solutions Manual – Whitlock
What does the p-value tell us? - answers-the probability of getting our observed result or
something more extreme due to chance, if the null hypothesis is TRUE
false positive - answers-when you reject your null even though its true
false negative - answers-when you fail to reject the null even though its false
if p=0.05, the probability of getting a false positive is 5%
nominal variable - answers-summarized using counts, percent population
if you have 2 values for a measurement variable, consider it a nominal variable
What do evil scientists do? - answers-run multiple tests and publish the results of the one that
best supports their prediction
probability - answers-the PROPORTION of individuals in a population that have a particular
characteristic
null hypothesis - answers-the statement you want to test (that things are the same as each
other)
