Why should an experiment even have a control group?

To show there is a measurable change in a treatment.

What is an experimental group?

The group that receives treatment.

What is a dependent variable?

The variable you measure or observe.

How many controlled variables should you have in an experiment?

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

What is an independent variable?

The one condition you change in an experiment.

What is a controlled variable?

A variable that DOES NOT change during an experiment.

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.

What is a control group?

Like experimental group, but receiving no treatment.

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

Claim, Evidence, Reasoning/Rebuttal

Should you incorporate your variables into your hypothesis if possible?

Yes, that would make a more controlled experiment.

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

So someone could duplicate your study.

What exactly is a variable in an experiment?

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

In order for a question to be "testable" it must be able to be investigated.
True
False

Why should an experiment even have a control group?
So the lab interns have more data to analyze. Dance, swine!
To increase the number of controlled variables.
To show there is a measurable change in a treatment.
To arbitrarily include more people in a study.
3
What is an experimental group?
The group that receives treatment.
The group that does not receive treatment.
The group including the researcher for testing.
The group composed of only dependent variables.
4
How many dependent variables can be tested at once in an experiment?
As many as you please.
3 shalt be the number of the counting. No more. No less.
Only one.
Zero. We don't actually want to do a science.
5
What is a dependent variable?
The variable you change in a study.
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!
6
Why would it be important to maintain measurement consistency across an experiment?
Pick the first one.
Seriously, just pick the first one.
Not this choice.
Reduce the chance of error.
7
How many controlled variables should you have in an experiment?
1
The more, the merrier. Control is good in an experiment!
3, 6, 9
Science, you fine. Shake it, shake it fo me one mo time.
8
What is an independent variable?
Two or more conditions you change during an experiment.
The one condition you change in an experiment.
The part of the experiment that is measured.
The one condition you leave the same in an experiment.
9
What is a controlled variable?
A variable that does change during an experiment.
The variable you hypothesize to experiment with.
A variable that DOES NOT change during an experiment.
The variable you measure.
10
What are two ways data should be expressed in a scientific study?
Random Lists and Scribbles
Charts and Graphs
Tables and Chairs
Apple Pie Charts and Graphing Calculators
11

Which of the following is not testable?
How many hairs are in the average man-beard?
Flannel shirts keep the wearer warmer than no shirt at all.
How much peppering (grey color) is ideal in a man's hair?
How many hairs are in the average man-bun (top-knot)?
13
Why would a scientist repeat an experiment with the same variables exactly?
To look for new answers.
Boredom, mostly.
To test two independent variables simultaneously.
To confirm findings.
14
Why do scientists use words like results "support" or "fail to support" hypotheses?
Scientists have fragile egos. Be gentle, lest they bruise.
Right and Wrong were already used by logicians.
A hypothesis is always correct.
Science doesn't offer conclusive proof of a knowledge claim.
15
What is a control group?
The group that receives the experimental treatment.
Our Reptilian Overlords.
Like experimental group, but receiving no treatment.
The hypothetical...variable...procedural conclusion...
16
What is a proposition based on existing knowledge used to explain an occurence?
Answer
Question
Hypotenuse
Hypothesis
17
What does the acronym C.E.R. stand for?
Chronic Ease of Research
Claim, Evidence, Reasoning/Rebuttal
Creating Expensive Reindeer
Control, Experiment, Results
18
Should you incorporate your variables into your hypothesis if possible?
Yes, that would make a more controlled experiment.
No, I prefer anarchy.
I love lamp.
No, that requires too much work.
19
What is the importance of precisely and accurately recording methods/procedures?
So someone could duplicate your study.
To make your hypothesis better.
How else will you hit the 15 page publication requirement?
To increase data efficiency.
20
What exactly is a variable in an experiment?
The step-by-step instructions for the experiment.
The location where research is accessed.
Any factor that can be controlled, changed, or measured.
The raw data collected.
