How do you find the mean?

How do you find the median?
The value in the middle of the data.
What is an independent variable + where does it go? How about dependent variables?

Give an example of an independent variable.
(anything that makes sense)

What data shows direct or indirect relationships?
Direct follows the best path line upward, indirect follows the best fit path downward.
What data shows a constant relationship?
A straight line of best fit.
What data shows nonlinear relationships?
Data that does not correlate.
What data shows peak relationship?
A graph that peaks in the middle.
How many digits should you estimate to?
One digit after the shown measurements.
Mass VS Volume? Define both.
Mass is how much matter is in an object. Volume is how much space something takes up.
Make sure you know the differences of metric unit prefixes!
Happy testing
