BIOLOGY 130 Lecture 24: Eavesdropping
Document Summary
Lie eggs on the male cricket that eventually kill the cricket. Male crickets make songs using file and scraper. some males lack the file and scraper. P value is what your statistical test gives you. If p > 0. 05 we can conclude that random chance is likely to account for observed. If p <= 0. 05, we can conclude that the groups are significantly different from random. Chi squared test: for categorical variables (yes, no), # in each group different from. Ex: you observe that 40 out of 50 chickadees that visit the feeder choose sunflower seeds and 10 out of 50 eat millet. You are studying insect predation with cages blue jay predators. Take home: be able to do similar to those on the hw. Hummingbirds are attracted to flowers that are red because they are a great source of nutrition, which keeps them healthy for mating habits.
