2.
What is the relationship between observation and gathering data?
a)
To get observation, you have to gather information, which is data.
b)
To get data, you have to gather information, which is observation.
c)
There is no relationship between observation and data.
d)
Observation and data are the same thing.
3.
How do you make an inference?
a)
You gather information.
b)
You find out the manipulated and responding variables.
c)
You use prior knowledge or experience to make a logical interpretation.
d)
There is no such thing as an inference in science.
4.
What is the difference between a manipulated variable and a responding variable in a controlled experiment?
a)
A manipulated variable is the same thing as a responding variable.
b)
A controlled experiment only has a manipulated variable.
c)
A controlled experiment only has a responding variable.
d)
A manipulated variable is the variable that is deliberately changed, unlike the responding variable, which is the variable that is observed and that changes in response to the manipulated variable.
