EED Lab Practical questions with
verified solutions
Can you generate a null and alternative hypothesis? Predictions from them? - correct answer
✔✔Hypothesis: : If the leaf is thinner then there will be more bites. Positive relationship between
thickness and bites.
Predictions: Positive relationship between thickness and bites.
What are independent variables? - correct answer ✔✔the variable is represented on the x axis
ex: Dewlap Size
What is a dependent variable? - correct answer ✔✔Y axis (variable you are testing for)
Ex: # frequencies (Number of bites on leaves)
Can you interpret a bar or line graph? - correct answer ✔✔Bar: Brown Anole lab with the equation and
different frequency
Line Graph: Also brown anole with the female and male frequency scale
Regression of points? - correct answer ✔✔Trendline
What is mean? - correct answer ✔✔Average of all the data points (sum of data)/amount of #'s
What is Standard Deviation? - correct answer ✔✔=standard deviation in excel (dispersion of data
relative to mean calculated by squareroot of varients
What is correlation coefficient? - correct answer ✔✔r^2 on a graph (measure of linear correlation
(relation between 2 variables))
How might you put a formula into excel? - correct answer ✔✔=average(),=st.dev()
, What is sexual selection? - correct answer ✔✔when one mate chooses another mate based on a similar
trait (male with bigger dewlaps attract more females)
What is a peer reviewed source? - correct answer ✔✔Journal, Study, lab report that has been edited and
read by peers in the field
What is a citation? - correct answer ✔✔citation quotation and work used by another author put into a
project mentions/credits at end
What are the important parts of a citation? - correct answer ✔✔Last, First, middle I. TITLE published by
date published/year and date accessed
Spirogyra sp. - correct answer ✔✔Looks like spaghetti
Supergroup: Chlorophytes
Closest supergroup: Rhodophyta
Volvox sp. - correct answer ✔✔looks like lines and circles
Supergroup: chlorophyte
Shape: pink circles with dots in the circle
Diatoms sp. - correct answer ✔✔Supergroup: Stramenoplias
Everday uses: foresic examination
environmental indications
water quality identification
Paramecium sp. - correct answer ✔✔Look like ovals
Supergroup:Ciliate
Diagnostic
Presence of thousands of cilia covering the body
