A dependent variable is

• A variable that is changed by the the person doing the experiment
• A variable that is measured by the person doing the experiment
• A variable that is kept the same by the the person doing the experiment
• Any of those

An independent variable is

• A variable that is changed by the the person doing the experiment
• A variable that is measured by the person doing the experiment
• A variable that is kept the same by the the person doing the experiment
• Any of those

A hypothesis is

• A table of all risks and eithical considerations
• The title of the experiment
• A prediction of outcomes
• What the purpose of the experiment is

Accuracy is

• Producing a measurement as quickly as possible.
• Producing the same measurement every time.
• Producing the same measurement when measured by different experimenters.
• Producing a measurement as close as possible to the true value of the quantity.
