Working Scientifically Flashcards
Define
independent variable.
the variable you change
Define
dependent variable.
the variable you measure when you change the independent variable
Define
control variables.
the variables that you keep the same
Define
control experiment.
an experiment that is kept under the same conditions as the rest of the investigation, but doesn’t have anything done to it
this is so that you can see what happens when you don’t change anything
Define
accurate data.
data that is very close to the true answer
Define
precise data.
data that is all really close to the mean of your repeated results
(not spread out)
Define
resolution.
the smallest change a measuring instrument can detect
Define
anomolous result.
a result that doesn’t fit in with the rest at all
Define
categoric data.
data that comes in distinct categories
Define
discrete data.
data that can be counted in chunks
Define
continuous data.
numerical data that can have any value within a range
Define
positive correlation.
as one variable increases the other increases
Define
negative correlation.
as one variable increases the other decreases
Define
no correlation.
no relationship between the two variables
State the
order of unit prefixes in ascending order.
