Midterm II Practice Questions
Which of the following is characterized by its close, symbiotic relationship with plants?
A. Chytridiomycota
B. Zygomycota
C. Glomeromycota
D. Ascomycota
E. Basidiomycota
Practice Question
Whether a plant is planted with other individuals of the same species or of different species is known to affect the growth of that plant. Dr. Guthrie is conducting an experiment to evaluate this concept with the Blazing Star (Mentzelia lindleyi), a native California wildflower. He has three treatments, a focal Blazing Star grown with A) other Blazing Stars, B) a mix of Blazing Stars and California Poppies, C) only California Poppies.
1) What are Dr. Guthrie's null and alternative hypotheses?
2) What two issues should Dr. Guthrie watch out for when designing his experiment?
3) Dr. Guthrie finds that his data are not normal and can't be transformed. However the variances of the three groups are equal. Which test would be most appropriate?
4) Dr. Guthrie gets a test statistic of 7.5 and a critical value of 6. What should he conclude?
Fixed versus Random Effects
Today we discussed Fixed Effects and Random Effects ANOVA. Design two similar studies that use either Fixed or Random Effects explanatory variables. Post your studies below.
Name that Test
Krief et al. 2014 studied group composition of wild chimpanzees during feeding sessions versus non-feeding times (Clips). Using the graph below, what type of analysis do you think they used for their study?

Who am I?
I'm a species that requires finding a mate of the opposite mating type using pheromones. Once I find my mate, we create offspring by fusing our hyphae together and exchanging genetic material. Who am I?
