Making a decision is pretty tricky, let alone the correct one.

These sessions will enable you to use data to calculate the chance of error in the decision you have made. The two outcomes we will look are:
- You stated that something has changed, even though it was a false assumption.
- You stated something hasn’t changed even though it was a true assumption.
In medicine, we use these error rates to calculate the chance of misdiagnosis or not picking up the illness in the first place.
