LIS3DH spike in acceleration value

I have been doing some testings recently with the LIS3DH accelerometer to measure machine vibration, and I have come across 2 things. I am using the accelerometer to sample 512 points at a 1.1Khz sampling rate. I have it set a normal mode, with ODR =1.3Khz, out of the 512 points I sometimes get 1 or 2 outlier points with very different values from the rest, it seems to happen randomly but I am not sure of the source (picture attached).

My second question is about the accelerometer's natural frequency as i could not find it in the datasheet.

Regards.
