Before the intervention in the treatment group and the control group, the Independent Sample t Test = 0.139 <0.05 means that there is no difference between the treatment group and the control group, whereas after intervention in the treatment and control groups obtained Independent Sample t Test = 0,000 <0.05 means that there is a difference between the treatment group and the control group after the preceptorship method is done.
