Because by taking 3 readings you allow for unknown variables to change the results slightly so then by averaging them you get a more valid and reliable reading because it has accounted for unknown error
To make sure they have accuate readings.
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.
First the only thing that an IQ test measures is the ability to do IQ tests. 100 is considered average IQ.
So it is easier to work out a mean (average) and makes your results more accurate. Also you can spot outliers. But it's incredibly annoying :L
If you are following the scientific method for an inquiry or experiment, then yes, it should be.
Temperature measures how fast molecules are moving or in scientific terms it measures the AVERAGE KINETIC ENERGY in a system. Temperature measures how fast molecules are moving. :):)
One of the measures of central tendency IS the average, also known as mean. You can't calculate the average from other measures of central tendency.
Measures of Central Tendency (Types of Average) are:-Mathematical Average Arithmetic MeanGeometric MeanHarmonic MeanPositional Average MedianModePercentileCommercial Average
To make sure they have accuate readings.
No, the odometer measures the distance traveled by a vehicle. The speedometer measures the speed at any given moment in time, but not the average speed.
No, a thermometer measures the temperature of a material, which is a measure of the average kinetic energy of particles in the material.
Typically, fasting is not required for an A1C test, as this blood test measures average blood glucose levels over the past 2-3 months. However, it is advisable to follow any specific instructions provided by your healthcare provider.
Find the average of your readings. Divide 220 volts into it and you will have your answer.
The temperature of a gas is related to the average kinetic energy of its molecules, which is directly proportional to their speed. Therefore, temperature indirectly measures the average speed of air molecules.
The only way to get an "average" reading is to take multiple readings, not just one. Your question sounds like the glycated hemoglobin or "A1C" test. The average lifespan of the red blood cell is 120 days, so checking A1C levels about every 90 days would be about right. For more detailed information, please see link below:
In temperate zone away from water, in desert areas, and at higher altitudes.
Temperature measures the average kinetic energy of air molecules. As the temperature increases, the molecules move faster and have higher kinetic energy.
