Scientific Method
Measurements or observations collected and recorded in an experiment or investigation are known as
what is data
When an experiment is redone by using different researchers
What is replication
Its a type of study that is used to observe and learn; does not control or affect the events
What is simplify them
Acquiring scientific knowledge requires
what is asking questions
The measured outcome
What is the dependent variable
It is for precision
What is repetition
This type of study can create conditions in a lab setting
A scientific model can be improved by
what is learning new information
Are observations of similar events that have been observed repeatedly (HINT Law or Theory)
what is a scientific law
Graphed on the X-Axis
What is the independent variable
An experiment is conducted multiple times by the same scientist
What is repetition
The limitation of this study is that it can have human error, and it cannot determine why an outcome occurs
Name three types of scientific models that can be utilized
An explanation based on evidence that is not directly observed; rather it's based on logic and reason
what is an inference
A group in a scientific experiment that serves as a reference for comparison to the experimental group is a
control group
Gives us an indication of whether the measuring device measures what it claims to be measuring
what is validity
The benefit of this type of study is that it can identify patterns, and may help understand the past.
what is a comparative study
Attempts to explain why something happens
It is based on nonfactual data
Which graph would be used to display data or information that changes continuously over time?
what is a line graph
Refers to how close a measurement is to the true or accepted value
What is accuracy
A limitation is that may cause research biases, and it can only conclude possible associations between variables
____ are repeated observations and scientific investigations (HINT Law or Theory)
What is a scientific theory
Compares two or more things through the use of observation with no manipulation of variables
What is a comparative study
