Title for a graph
Dependent variable
Hypothesis
Independent variable
4
A control group helps an experiment because it give the scientist
More participants
None of the above
A group to compare experimental results to
More work
5
Does correlation equal causality?
Not necessarily
Yes
As long as your mate reckons it does
Always no
6
Which is not a type of correlation ?
positive
upward
negative
no correlation
7
How is a control variable different than the dependent variable?
Control variables are what the scientist is testing.
Control variables remain constant.
Control variables are the outcome.
Control variables are the same as dependent variables.
8
What is theoretical/calculated probability?
The theory of probability
The likelihood of an event occurring
The probability recorded during chance experiments
The probability we expect to occur during chance experiments
9
The dependent variable...
Is the result
Stays the same
Is changed by the scientist
Is known before the experiment
10
Which scenario would be the most credible and accurate?
Not controlling variables and doing one trial.
Controlling variables and doing 100 trials
Controlling all variables and doing one trial
Not controlling variables and doing 100 trials
11
Roosevelt football team wants to know if protein shakes makes you stronger. What's the Dependent Variable here?
The age of players

Player Strength
12
What is scientific theory?
It is a guess or conjecture about natural phenomena.
It is a collection of experimental data
It is an assertion of scientific fact.
It is an explanation of the why or how of natural phenomena
13
What is statistics about?
analyzing graphs
organizing data
interpreting data
all of these
14
If an experiment cannot be repeated by other people or scientists then it's
Reliable
Not reliable
a good experiment
Perfect
15
This is when you state whether your hypothesis was correct, your errors, and what you do next.
Procedure
Graph
Problem
Conclusion
16
What is the independent variable
The variable measured
The outcome
The variable being tested and changed
When you hold something constant
17
What is the difference between a theory and a law?
Theories can be proven wrong, laws cannot.
Laws explain what occurs, theories explain why they occur.
Laws explain why things occur, theories tell what occurs.
Theories aren't certain, laws are.
18

All of these
Be based in logical observations
Make a prediction
20
Why do scientists use correlations?
It's unethical to study.
All of these
It's impossible to study.
It happened too long ago for us to study.
21
What is the difference between the experimental group and the control group
The experimental group is larger
The experimental group gets the Independent Variable done on them
The experimental group is independent
The experimental group gets results
22
What is a prediction?
The outcome we expect to see if the hypothesis is correct
The answer to the experiment
What you are trying to answer in your experiment
An answer to the question
23
What do you need in order to begin the scientific method?
Hands
Tools
A degree
A problem/question
24
The purpose of a procedure is to....
Show others the steps you took to do the experiment.
