Variables & Subjects
Your two types of subjects.
What are Control Subjects and Experimental Subjects?
This type of graph would show change over time.
What is a line graph?
A falsifiable hypothesis is one which...
*Hint: what does it mean for it to be falsifiable.
What is can be tested and may be (not necessarily will be) found false?
This is the basic unit for length in the metric system.
What is the meter?
This is what a theory is.
What is a hypothesis which has been tested many times and has never been found false?
The variable that you manipulate directly.
What is independent variable?
The name of the axis where the independent variable is placed.
What is the X-Axis?
A possible, testable explanation for some observed phenomenon.
What is a HYPOTHESIS?
The the number of times a hypothesis must be tested to become a theory.
What is many?
The variable that you expect to respond to the treatment.
What is the Dependent Variable?
The step in the scientific method where you gather data.
What is the Results?
A device best used to observe microscopic objects, like cells.
What is a microscope?
Variables that could affect the dependent variable, but are not the independent variable.
What is are controlled variables?
The dependent variable goes on this axis.
What is the Y-Axis?
The type of data which deals only with whole numbers.
What is Discrete Numerical Data?
In the metric system, a change in units (e.g. - from cm to mm or cm to dm) involves a change by a factor of what.
What is 10?
Data where are all very close in their values are said to be this.
What is precise?
The subjects which receive the independent variable.
The Experimental Subjects.
You would use this type of graph to compare the average of two or more subjects.
What is a Bar Graph?
The analysis of your data and suggestions for future experiments occurs in this portion of the Scientific Method.
What is the Conclusion?
There are this many centimeters in a meter.
What are 100 centimeters?
We can tell if the values of our data are spread apart by using this statistical calculation.
What is a standard deviation?
