Answer 1

Behavioral ecologist

Question 2

In this lab we will perform ……..experiments

Answer 2

behavioral ecology

Question 3

terrestial isopods also known as

Answer 3

Pillbugs, woodlice, and roly-polys respond to abiotic factors

Question 4

can be found under stones or logs feeding on decaying plant and animal matter

Answer 4

crustaceans

Question 5

they respire through

Answer 5

gills that must remain moist

Question 6

Formal hypothesis testing using the x^2 goodness of fit statistical test

Answer 6

compares observed results with expected outcome

Question 7

Expected outcomes are based on

Answer 7

null hypothesis of no preference.

Question 8

Enviromental varibles

Answer 8

light/dark, moist/dry, surcose solution/saline solution

Question 9

we will develop a…….and………

Answer 9

null, alternate hypothesis

Question 10

formal hypothesis testing using the

Answer 10

x^2 goodness of fit statistical test
- compares observed results with expected outcomes

Question 11

Based on this alternate hypothesis,

Answer 11

we can make a quantitative prediction:

Question 12

We can test each alternate hypothesis using the

Answer 12

Chi Square (χ2) Goodness of Fit Statistical Test

Question 13

Expected outcomes are based on

Answer 13

a null hypothesis of no preference.

Question 14

The first column in the table contains

Answer 14

• degrees of freedom (df),
• determined by subtracting 1 from the number of choices that the isopods had in the experiment.

Question 15

statistically significant

Answer 15

observed difference or effect in a dataset

Question 16

not significant

Answer 16

observed difference or effect is not large enough to conclude that it is real and not simply due to chance

Question 17

cannot reject the null hypothesis and our alternative hypothesis

Answer 17

not supported by the data

Question 18

we can reject the null hypothesis and conclude that our alternate hypothesis

Answer 18

supported by the data
