Vivacious Variables
The type of variable that is measured
What is the dependent variable?
The first step of scientific method
What is an observation?
The variable that goes on the X-axis of a graph
The clarity of an image
What is resolution?
The type of vairable that is controlled or manipulated
What is the independent variable
This step of scientific method involves making a prediction.
What is hypothesizing?
A variable that is not documented on a graph
What is a control variable?
The amount that the apparent size of an object is increased.
Sally conducted an experiment where she tested how much juice her little brother drank per day depending on the weather for that day. She made apple juice available to her brother each day but made sure no other kinds of juices were available to him.
In this example, ________is the control variable
What is the apple juice?
These 3 things are needed in order to observe the relationship in question for an experiment.
Control, Independent, and Dependent Variables
The graphical relationship where as x increases, y decreases
What is an inverse/indirect relationship?
What is the SEM?
Sally conducted an experiment where she tested how much juice her little brother drank per day depending on the weather for that day. She made apple juice available to her brother each day but made sure no other kinds of juices were available to him.
The dependent variable in Sally's experiment was ______What is the amount of apple juice the little brother drank in a day?
This step involves documenting information and publishing it.
What is sharing/communicating findings?
The type of relationship where as x increases y increases dramatically, but then after a little while the effect levels off and increasing x no longer impacts y.
What is a logarithmic relationship?
What is the drawing magnification of a drawing if the specimen is 2mm in real life but the drawing is 200mm?
Frank decided to find out if a cat crossing his path was actually bad luck.
He recorded the number of times a black crossed his path/month and then counted the number of times something bad happened to him in the same month.
He took data for August, September, October, and November.
What is the problem with Frank's "experiment" in terms of variables.
He is measuring both variables, so he cannot find causation only correlation. He doesn't control any of them.
What is new observations/questions?
When we use a best fit line to determine the relationship between variables and use this to estimate data points that were not directly measured.
What is extrapolation?
If my FOV(low) is 4mm.
And my total magnifications are low: 40X med: 100X and high: 400X
What is the FOV(high)?
