Difference between determine and decide

Can anyone give me the difference in meaning of ‘determine’ and ‘decide’.

To me, determine implies using data or some other scientific method to calculate the correct answer or solution. Decide implies more that there is no “one correct answer”, so personal choice comes more into play.

So you mean we can use ‘decide’ on normal circumstances. Am i correct.

Not necessarily - I would “determine the correct answer on a test” but “decide where to go on holiday” and often there are situations where either word would be fine.
