I was checking a 3-axis accelerometer sensor an I found out this one https://www.digikey.it/it/datasheets/analogdevicesinc/analog-devices-inc-adxl335
Reading the datasheet, on page 6 under TYPICAL PERFORMANCE CHARACTERISTICS, all the graphics have on the Y the % of Population.
I can't understand what it refers to... Is it a statistic about the possible output of the sensor?
