• materials or equipment

• qualitative data

• hypothesis

The outcome factor or the variable that may change in response to the changed factor

• results

• data

• dependent variable

• quantitative data

result from imperfections in the tools used to take the measurements

• instrument errors

• controlled variable

• participant errors

• scoring errors

a judgement based on the information obtained

things can be avoided when collecting data such as spilling chemicals and using the wrong equipment

Error due to instrument giving a small reading when it should read zero

• division error

• reading error

• parallax error

• zero error

standard quantities used to specify measurements such as meters for distance and degrees Celsius for temperature
