experiment design Flashcards
what is the controlled variable
these are the variables which are kept the same throughout.
what is the independent variable
CAUSE - the variable you purposefully change
what is the dependent variable
EFFECT - the variable that changes as a result of the change in independent variable
what is the purpose of a controlled experiment
to prove only the independent variable is the variable that is changing to the dependent variable
what does repeating experiments lessen the chance of
the results being atypical or caused by an error or fluke
when are semi-log graphs used
they are used for numerical data which increases rapidly or in large steps
do you need to quote data
yes!!
what should be included in a conclusion for an experiment
- they should relate to the aim of the experiment or a piece of field work.
- it should relate to the independent and dependent variables
- do NOT simply restate the results
