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

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.


What blood test measures average blood glucose for 90 days?

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:
