Repeated readings give more accurate results. The more readings you have, the less likely it will be that your average was effected and skewed by one part of the experiment (unless of course, you're reading the whole thing in the wrong way). In science you also do tests more than once and have a large amount of test subjects for the same reason.

Why are there differences in repeated readings?
there are differences in readings for many reasons. it could be the environment affecting the experiment, the equipment may be faulty or the method of measurement may be incorrect
Why is it necessary to take more than one readings in an experiment?
Basically, so that if one reading is skewed due to human error or other, then there will be other readings to compensate.
How do you know if something is controlled in science?
if the experement can be repeated and the same results made then the experement is controlled if not the experement is not controlled
Why do scientists take lots of data and look at the average?
To make sure they have accuate readings.
What are the precautions for a density experiment?
Make sure that first you weigh the object and then find its volume because if you find the volume first the object will get wet and the mass of the object will not be accurate.When you are using the measuring cylinder to find the volume make sure you read at eye-level and at the bottom of the meniscus.Always take repeated readings when finding the mass.
Why is it important to take at least 3 readings for each test?
It may depend on what test you are referring to. For example, taking several readings may reduce biassing, or to show that the test can be repeated and produce the same outcome. Generally, taking multiple readings is recommended to simply sustain your data and final conclusion(s).

What should you do to increase your reading rate-?
One way to increase your reading rate is to practice timed repeated readings.
What is the difference between a good science and a bad science?
good "science" or a good experiment can always be repeated with the same result
What do Cardiographer do?

it is the something that stays the same in an experimentor something that is repeated in the project.

How is science involved in a car?
Without science, the computers used in cars today wouldn't be able to monitor everything from engine readings to whether or not you were speeding at the time of a crash.
