When looking at buying a car, the color is a variable with many of these
What are values
100
These are important because they test whether or not a hypothesis is correct
What are experiments?
100
This is how close a measurement is to the true value
What is accuracy
100
A quantity which can have many values is a ______.
What is variable
100
The height of the ramp was this in our experiment
What is the independent variable
200
In science experiments there are many variables that can be measured. These are three possibilities
What is time, mass, position, angle, temperature, volume, etc
200
In an ideal experiment, this is the number of variables being tested.
What is one?
200
This is a mathematical diagram showing one variable on the vertical axis and the other on the horizontal axis
What is a graph?
200
A situation set up to investigate the relationship between certain variables is called an _________.
What is an experiment
200
This was the dependent variable
What is the distance the cars traveled
300
Graphs show relationships between variables. When the graph shows a pattern there is this kind of relationship.
What is strong, direct, or inverse?
300
Finding this from a lot of data can help your results be more accurate than if you just took one result.
What is average
300
This is the process of evaluating data
What is analysis
300
The description of how an experiment is done, including the equipment, techniques used and the type of data collected is the ______.
What is procedure
300
The relationship between the height of the ramp and the distance the cars traveled was this
What is strong, direct, Etc
400
This variable always goes on the y-axis of the graph
What is the dependent variable
400
This is when others are able to repeat an experiment and get the same result
What is reproducibility
400
This is the variable changed by the experimenter and/or causes the change
What is the independent variable
400
The sum of all measured values divided by the number of measurements is called the __________ value
What is average
400
This is why different cars went different distances
What is control variables: weight, wheel friction, etc
500
Math is often used in science. Experiments sometimes use these. They can also help to make, find and check these.
What are formulas or equations?
500
This has to be less than the errors in order to be significant
What are differences
500
This is a variable that is kept constant in an experiment
What are control variables
500
A statement of what was learned in an experiment is called a ______________
