So I found this very useful link to implement MPU9250 with arduino:
However, I have doubts regarding how the accelerometer and gyroscope noise calculated from the datasheet (as mentioned in the link).
If anyone knows how these values are calculated, kindly explain.

The accelerometer and gyroscope values given in the datasheet for MPU-9250 are rms values. The GyroscopeNoiseMPU9250 and AccelerometerNoiseMPU9250 are calculated as follows:
RMS Noise of Gyroscope= 0.1⁰/s-rms
Deviation of Noise= =3.0462e-06 rad/s= GyroscopeNoiseMPU9250
RMS noise of Accelerometer = 8 mg-rms
= 0.0784 meter/-rms
Deviation of Noise = = 0.0061 meter/= AccelerometerNoiseMPU9250
