Oversampling - FXOS8700CQ

What exactly is Oversampling Rate (OSR)? If for example I set an ODR of 100 Hz for the magnetometer at an OSR=7, does this mean that the magnetometer will gather 16 samples, process them somehow and of all these 16 samples will return 1 as an output? What kind of processing is happening? (eg. Is it used any kind of averaging function?) Is oversampling having some kind of latency in the data (meaning that for a movement, we have some kind of hysteresis until we detect it)?


Thank you very much
