A valid one. An experiment cannot conclusively prove anything if more than one independent variable is altered at a time. That being said, many dependent variables could show change and the experiment would still be valid, as long as only one independent variable was altered at a time. An experiment that changes only one variable at a time is called a controlled experiment.
i believe it is how long an experiment is going to take. for example, the testing range of an experiment with plants may take around a few weeks to months.
The definition of an experiment is a procedure that is done in order to make a discovery, test a hypothesis, or test a known fact. An experiment is often the testing of a scientific theory, although it can be applied to other fields as well, as long as it meets the criteria of the definition.

the amount you expect to gain in the long run over many plays
The expected value is the long-run average value of repetitions of the experiment it represents.
Expected value is called the long-term average because it represents the mean outcome of a random variable if an experiment is repeated many times. It takes into account all possible outcomes, weighted by their probabilities, providing a single value that reflects the overall tendency of the random process. Over numerous trials, the average of the observed outcomes will converge to the expected value, demonstrating its role as a reliable predictor of future performance.
A recommendation letter is typically expected to be about one to two pages long.

timber is expected to last at list 15-25 years.
It depends on what your experiment was. You should ask a teacher or someone that you know who has done this before.

The expected value is the average of a probability distribution. It is the value that can be expected to occur on the average, in the long run.
