Explanation:

Step1: Recall the formula for total degrees of freedom

The formula for total degrees of freedom ($DF_{total}$) in an ANOVA - type problem is $DF_{total}=DF_{among\ treatments}+DF_{error}$.

Step2: Identify given values

We know that $DF_{total} = 18$ and $DF_{among\ treatments}=6$.

Step3: Solve for $DF_{error}$

Using the formula $DF_{error}=DF_{total}-DF_{among\ treatments}$, we substitute the values: $DF_{error}=18 - 6$.

Answer:

12
