Why are several trials taken for each measurement in an experiment?

A good way to reduce error or increase measurement accuracy is to take several measurements and compute their average. In other words, you achieve accuracy through averaging. (This also validates the repeatability of the measurement.)

What is an error in measurement?
A error in measurement is when the measurement taken is not actually correct. For instance, you measure a gap as 49 centimetres wide. You cut the plank of wood to fit that measurement. Then discover the wood you have just cut is too wide to neatly fit the gap. There has been an error in the measurement you have taken.
How many different ways can you measure a puddle?
You could measure a puddle in various ways, which might, assuming basic instruments of measure are used, include:circumference or perimeter (linear measurement)color (subjective observatory measurement)color at different times of day and in different weather conditions, and so on (subjective observatory measurement)depth (linear measurement)surface area (area measurement)temperature of contents (Celsius)temperature of contents (Fahrenheit)time taken to be drunk by a dog of a particular age, weight and breed (time measurement)time taken to empty (time measurement)time taken to evaporate under various temperature controls (time and temperature measurement)time taken to fill (time measurementvolume of contents (capacity/volume measurement)weight of contents (weight/mass measurement)
Where is the measurement taken from to get the depth for footings?
The measurement is taken from the point above grade at which height the foundation will be at completion, taking into account the type of foundation material and the frost line, and the depth of the crawl space or basement, if any.
Is transmittance a more accurate measurement?
Transmittance is a measurement of the amount of light that is able to pass through a material, and it can be used to accurately determine the amount of light that is transmitted. However, the accuracy of the measurement depends on factors such as the quality of the equipment used and the conditions under which the measurement is taken. Therefore, while transmittance can provide an accurate measurement, it is important to ensure that proper procedures and equipment are used to minimize errors.
What is meant by measurement is accurate but not precise?
An accurate but not precise measurement would be an approximate measurement. For example, in cooking or baking, the ingredients list might indicate one cup of a certain item. Scientifically, however, one cup, (or 8 ounces) would not be a precise measurement for testing purposes. Instead, a precisemeasurement would be required, especially when the results of a specific test need to be reproducible and the quantities are minute, as in micrograms, for example. Accuracy in measurement is of closeness to the actual or exact, but precision in measurement is closeness to the same spot each time it is taken.
Why are several observation taken for each measurement?
Several observations are taken for each measurement to eliminate or decrease the margin of error.
Why do you take many trials for a experiment?
Many trials are taken in an experiment as a way to limit experimental error. For example, if you are timing how long it takes a ball to roll down an angled track, as a human being you might release the ball at the wrong time, or push the stop button on the timer early or late. By running multiple trials and averaging the results, these errors should balance themselves out and give a better result.

What is the purpose of serial?
A common design for estimating the concentrations of compounds in biological samples is the serial dilution assay, in which measurements are taken at several different dilutions of a sample, giving several opportunities for an accurate measurement. Curren tly, serial dilution is a standard tool in the fields of toxicology and immunology.Serial dilution helps to choose a dilution which is relevant to our experiment.Often the standard which is given to you in the lab is far to strong for the experiment and it needs to be diluted. But equally the equipment has a detection limit so we can't dilute it to much, or if it is too diluted the experiment might not work.
