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.

What is the difference between an independent variable and a dependant variable?
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.

How many times does a person need to repeat singing a 25 seconds song so that the probability of at least two of the times the recorded song be exactly the same between them is 90 percent?
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 several times?

What is a repeat trial?
Repeated Trails are the number of trails done during a scientific experiment with the purpose of getting a more accurate result.

How can you be sure the results of an experiment are accurate?
repeat your experiment a few times!! that's it, easy.
What are the variables used in an science fair project?
A well designed science fair project should have one independent variable, one dependent variable, and lots of factors that are held constant as you repeat the experiment several times to verify your results.
When is an experimental variable good and when should it be reduced or eliminated?
There are generally 3 variable in an experiment : the dependent, independent and the control variable. The independent variable is something you change in your experiment and affects the dependent variable, while the control variable is there to make sure the experiment is a fair test. (eliminate external factors) A variable is considered good when it allows you to find a relationship or to investigate your theory. eg. A simple experiment : To investigate whether length of pendulum affects the period of a pendulum. IN this case, your independent variable would be the length of pendulum(to be changed) while your dependent variable is the time taken for 1 oscillation. You can plot x-y graphs to find the relationship between the two to help you conclude your experiment. ( Wind factor should be eliminated as it will affect your readings). There is no control variable for this experiment as period is dependent only on length and gravity.(unless gravitational force changes) There are times when a variable can be affected by many other factors. So in your experiment, you might want to eliminate those factor so that you can make a conclusion.

Why is it important to limit the variables in an experiment?
To understand this you need to remember that the independent variable is a condition that you can change, and the dependent variable is the outcome that you see. If you have two independent variables, and you change both during an experiment, how are you going to tell which one caused the change to the outcome? So, you only change one independent variable at a time.
What is the difference between a dependant and independent variable?
a dependent variable is something that you cannot change but comes out as a result/an independent variable is something that you change in your experiment like the temperature of something or the amount of something
In an experiment to test the effect of excercise on the number of times a clothespin can be squeezed in 1 minute what is the dependent variable?
a single variable
Why do scientists repeat?
Scientists repeat experiments for reliability. The experiment must be repeated for the scientist to develop a theory. One experiment does not prove your hypothesis correct; therefore, it must be done a several times.
