What is a random error?

• results are under the true value

• errors that are randomly planned

• results are over or under the true value

• errors which are unavoidable

What is a systematic error?

• all results are either under or over the true value

• some results are under and over the true value

• errors that are systematically calculated

• errors that can be fixed by calculating an average errors that can be fixed by calculating an average

I have read all my burette readings not at eye level but from above

• Random error

• Systematic error
