This scientific inquiry process is most similar to:
A Network
A Circle
A set of Linear Steps
A Wheel with Spokes - ANS A Network
Which of the following is NOT true regarding the process of scientific inquiry?
Designing an experiment to test an unlikely hypothesis !
Accepting a hypothesis based on preliminary data
Developing a hypotheses based on a little known phenomenon
Running experiments with precision
Recording observations - ANS Accepting a hypothesis based on preliminary data
In the class experiment with termites, we tested if the termites were attracted to the ink line or
pencil line. In our experiment, _________ was the dependent variable and ___________ was
the independent variable. - ANS time termites spent on either ink or pencil line, presence of
ink

In our class discussion about termites, you learn that they spend most of their lives in complete
darkness feeding on wood. You know from experience that colors do not show up well without
light because the color receptors in our eyes (cones) do not work without the presence of light.
Knowing this, which of the following hypotheses is the most likely to have biological support? -
ANS Termites will have evolved mechanisms to travel that do not involve vision.
In the class experiment, why did we use the same termite for both the pen and pencil trials on a
single sheet of paper? - ANS To remove the effect of individual differences in termite
behavior from confounding the results.
In the termite class experiment, what was the primary reason for controlling for treatment
order bias by alternating whether the termite started on either the control or treatment trial? -
ANS Reduce the effects of sensitization and fatigue
Scientist use ________________ to get a sample that is a good representative of the
population. - ANS random sampling techniques
What level of measurement classifies data into mutually exclusive (non-overlapping) categories
in which no order or ranking can be imposed on the data? - ANS Nominal
Which of the following is true about descriptive versus inferential statistics?
You can make definitive conclusions from descriptive statistics alone.
Only inferential statistics allow us to generalize our findings to the entire population, so
descriptive statistics have an insignificant role in science.
You can determine inferential statistics from intuition alone.
Descriptive statistics are a good way to get an idea of what your data looks like. -
ANS Descriptive statistics are a good way to get an idea of what your data looks like.
A t-test is commonly used to test ___________ - ANS if means of two samples are different
from each other
