1.2 Measurement Flashcards
What variable goes on the y-axis
Dependent variable
How are direct graphs and indirect graphs different
Direct graphs have positive correlation having both side go up creating an upward line. Indirect graphs have negative correlation one side goes up and one goes down. This creates a downward sloping line.
What is the difference between interpolation and extrapolation.
interpolation is making predictions within the graph and extrapolation is making predictions outside of the graph.
If a data points are (2,4), (6,10), and (4,12) what would be a good scale for the x-axis
A good scale would be counting by ones because there is not a big range.
Which is a better title? Temperature, or temperature of the water during the winter time in Panama City Beach, Florida (C°)
Temperature of the water during the winter time in Panama City Beach, Florida (C°). This title is more specific and gives the reader a better understanding of what the graph is trying to interpret.
Should you use a straight edge when constructing a graph
Yes, this makes you graph neater and easier to read
When plotting a point on a graph what is first the x or y
the x
What is Standard deviation
the measure that is used to quantify the amount of variation in a set of data
The variance of a data set is 48. What do you estimate the Standard Deviation would be
around 6.9
What is the first step in calculating the standard deviation for a data set
finding the mean
if you have a small standard deviation what can you assume about the data points
you can assume that they are all close to the mean
What shape should a standard deviation be
it should be a slow curve like graph
Does having a large deviation make it easier to find outliers in data
yes
How do you find the variance in a data set
you square the differences from the mean and add them all together, you then divide them by how many there are
What is the base unit for length
meter, m.
