Definition:____________________________________________________________________
Tools: ___________________
Time is always the _________________ because it _______________________ and the scientist decides the interval.
Unit: seconds (this is the standard unit however there are others).
Definition: how long it takes for something to happen.Tools: stopwatch or clock
Time is always the independent variable because it does not depend on anything and the scientist decides the interval.

It is often easier to transform data into a GRAPH to get a
visual picture.
Definition: A model that helps us to picture the relationship between
two variables.
Consistent Data
What does it mean to be consistent? Which Group has the most
consistent data?
Precision vs. Accuracy• _________________
refers to how close a measurement is to the true value.
• ________________ describes how close together repeated measurements are. Goes along with “most consistent”
Accuracy vs. Precision• Accuracy refers to how
close a measurement is to the true value.
