If you did the experiment wrong
you might be too young
Fist the scientist figures out the aim of their experiment. Then they make a prediction. And then they make a theory before actually doing their experiment. After the experiment they make a conclusion and then evaluate their experiment (what went wrong, how things could be better...). Hope this helped! :)
Experiment
Data is considered invalid when it is wrong or has changed. Data represents facts that are recorded, so any alterations made to it can make it invalid.
Scientists repeat their experiments because to make sure that their results are correct.

Simple. Try new things and experiment, until you make your very own delicious meal.
A controlled experiment might be impossible if there are too many variables that cannot be controlled or if it is unethical or impractical to manipulate certain variables. Additionally, external factors outside of the researchers' control can also make it difficult to ensure a controlled environment for the experiment.
