What does the acronym C.E.R. stand for?

Claim, Evidence, Reasoning/Rebuttal

What is the importance of precisely and accurately recording methods/procedures?

So someone could duplicate your study.

What is an experimental group?

The group that receives treatment.

What is a dependent variable?

The variable you measure or observe.

What exactly is a variable in an experiment?

Any factor that can be controlled, changed, or measured.

What is a control group?

Like experimental group, but receiving no treatment.

Should you incorporate your variables into your hypothesis if possible?

Yes, that would make a more controlled experiment.

What is an independent variable?

The one condition you change in an experiment.

Why should an experiment even have a control group?

To show there is a measurable change in a treatment.

Which of the following is not testable?

How much peppering (grey color) is ideal in a man's hair?

Why do scientists use words like results "support" or "fail to support" hypotheses?

Science doesn't offer conclusive proof of a knowledge claim.

How many controlled variables should you have in an experiment?

The more, the merrier. Control is good in an experiment!

What is a controlled variable?

A variable that DOES NOT change during an experiment.

To make your hypothesis better.
So someone could duplicate your study.
To increase data efficiency.
How else will you hit the 15 page publication requirement?

What is an experimental group?
The group including the researcher for testing.
The group composed of only dependent variables.
The group that does not receive treatment.
The group that receives treatment.

ALL OF THEM. GOOD LUCK FIGURING OUT WHAT HAPPENED!
6
What is a dependent variable?
The variable you measure or observe.
The variable you leave the same in a study.
Your 24-year-old kid who moved home after college...LEAVE!
The variable you change in a study.
7
Why would a scientist repeat an experiment with the same variables exactly?
To test two independent variables simultaneously.
To confirm findings.
Boredom, mostly.
To look for new answers.
8
What exactly is a variable in an experiment?
The location where research is accessed.
The step-by-step instructions for the experiment.
Any factor that can be controlled, changed, or measured.
The raw data collected.
9
What is a control group?
Like experimental group, but receiving no treatment.
The group that receives the experimental treatment.
The hypothetical...variable...procedural conclusion...
Our Reptilian Overlords.
10
Why would it be important to maintain measurement consistency across an experiment?
Reduce the chance of error.
Pick the first one.
Not this choice.
Seriously, just pick the first one.
11
Should you incorporate your variables into your hypothesis if possible?
No, that requires too much work.
Yes, that would make a more controlled experiment.
I love lamp.
No, I prefer anarchy.

Answer
13
What is an independent variable?
Two or more conditions you change during an experiment.
The one condition you leave the same in an experiment.
The part of the experiment that is measured.
The one condition you change in an experiment.
14
How many dependent variables can be tested at once in an experiment?
Zero. We don't actually want to do a science.
Only one.
3 shalt be the number of the counting. No more. No less.
As many as you please.
15
Why should an experiment even have a control group?
So the lab interns have more data to analyze. Dance, swine!
To arbitrarily include more people in a study.
To increase the number of controlled variables.
To show there is a measurable change in a treatment.
16
Which of the following is not testable?
How much peppering (grey color) is ideal in a man's hair?
Flannel shirts keep the wearer warmer than no shirt at all.
How many hairs are in the average man-bun (top-knot)?

17
Why do scientists use words like results "support" or "fail to support" hypotheses?
A hypothesis is always correct.
Right and Wrong were already used by logicians.
Science doesn't offer conclusive proof of a knowledge claim.
Scientists have fragile egos. Be gentle, lest they bruise.
18
How many controlled variables should you have in an experiment?
Science, you fine. Shake it, shake it fo me one mo time.
The more, the merrier. Control is good in an experiment!
