Among other factors, the answer will depend on:
the variability of the response (dependent) variable,
the cost (disbenefit) of making the wrong decision based on the outcome,
the cost of conducting the experiment repeatedly.

In an experiment, the independent variable is the variable that can be altered or controlled to produce a change. The result being studied is the dependent variable, which is observed to change as the independent variable is changed.Example : In an experiment testing the effect of caffeine on reaction times, the amount of caffeine consumed is the independent variable and can be varied. The reaction times are the dependent variable, and a correlation (change in times) with the independent (amount given) is the information being sought.There are three kinds of variables. These are:Independent variable: is not affected by any effects in the experimentDependent variable: its reaction does depend on other variablesControlled variable: variable that you can control throughout the entire experimentTo put it simply, the independent variable tries to manipulate the dependent variable in an experiment.The independent variable (manipulated variable) is a variable that is changed by the experimenter. The dependent variable (responding variable) is what you are trying to determine in an experiment. My 6th grade science teacher taught us a poemThe manipulated is what you control the responding variable is your ultimate goal.

Karen and Jose are doing an experiment with a spinner and a coin.they spin the pointer on the spinner and flip the coin.then they record the results.they will repeat this experiment 15 times.show how they could organize a table about this experiment.
Since time is a continuous variable, the answer is that the song must be sung infinitely many times. Time might be a continuous variable, but recorded time is not.
why is it important to repeat an investigation several times?
