Because you declared statistician to be in namespace CISP430_A1. So it's name is CISP430_A1::statistician (unless you import that namespace), i.e. you should define your constructor
Code:
CISP430_A1::statistician::statistician() {...}

Probably because it does not know what statistician is. Qualify it with the name of the namespace or import the namespace.
