Quantitative
Qualitative
2
True/False - Data collected during experiments can be logically organized in tables, graphs, charts.
True
False
3
True/False - We repeat experiments many times to see if we will get the same results (improves test validity).
False
True
4
Which variable is deliberately changed in an experiment?
b. Controlled
c. Hypothetical
a. Dependent
d. Independent
5
How is it determined if a hypothesis is correct or incorrect?
Draw conclusions
Do an experiment
Don't do anything - who cares?!
Do research
6
What's the purpose of the experimental group?
It gets the dependent variable.
It gets both the independent & dependent variables.
It gets the independent variable.
Everything about it stays the same and it is used to compare.
7
What is the purpose of the hypothesis in an experiment?
It is gathering background info about your problem/question.
It is the problem or question that you want or need an answer to.
It is a testable explanation for details you observe.
It is a set of procedures that you follow to test your hypothesis.
8
Name the 2 variables in every experiment.
Observation & Analysis
Nemo & Dory
Independent & Dependent
Control & Hypothesis
9
All scientific investigations begin with:
b. Conducting an experiment
d. Forming a conclusion
c. Asking a question or observing a problem
a. Forming a hypothesis
10
What conclusion can be reached by the data shown in the graph?
Dissolved oxygen was lowest in June
Dissolved oxygen was highest in January
Dissolved oxygen was highest in December
Dissolved oxygen was highest in June
11
Name the 2 groups in every experiment.
Research/Hypothesis
Tigers/Lions
Independent/Dependent
Experimental/Control
12
What is a controlled experiment?
Where we only change one thing and keep everything else the same.
Where we eat a lot of pizza.
Where we don't change anything.
Where we change a lot of different things.
13
Which step would occur last in the Scientific Method?
b. Organize the data into charts, tables, and graphs
c. Publish the results
a. Analyze the data & d. Form a conclusion based on the data
e. Repeat the experiment to see if the data from the 1st one is reliable
14
True/False - A hypothesis can never be proven true beyond all doubt because new data can disprove it.
True
False
15
How might a hypothesis be stated for the experiment below?
High temperatures make enzymes react more.
If the temperature is low then the enzyme might react less.
If the temperature is high then the enzyme might react more.
Low temperatures make enzymes react less.
16
What name is given to the type of data that is descriptive rather than numerical?
Qualitative
Quantitative
17
Why should we only change one variable in an experiment?
So we can tell what we changed
So we can tell what we will measure
So we know that what we measure is because of what we changed
So we can tell what we kept the same
18
Which variable is what we measure in an experiment?
a. Dependent
b. Controlled
c. Hypothetical
d. Unidentifiable
19
What's the purpose of the control group?
It gets both the independent & dependent variables.
Everything about it stays the same and it is used to compare.
It gets the dependent variable.
It gets the independent variable.
