Does the LSM6DS3 IMU require temperature compensation?

I am developing a project with the LSM6DS3 IMU sensor. I found that the data I got is a little bit different at different time of the day. The test setup is basically the same. I suspect the differences is due to the temperature of the environment. Does the temperature affect the data? 

This sensor has an internal temperature sensor and I can read the temperature, do I need to do any compensation? If it does, how to do it?

As you can see from the datasheet, there is small dependency on the temperature:

The device already does internal temperature compensation, which is enough for standard usage of the sensor.

For very high accuracy you could do additional external the temperature compensation, but it is not easy. You would have to characterize you devices and evaluate the temperature dependency.
