2. The findings show that the mean for RNs’ knowledge of interpersonal and developmental theory is 23.1 while RPNs’ is 16.1. There is a difference between the two groups and RNs have a higher average score. The variance for RNs’ knowledge of interpersonal and developmental theory is 41.9 while RPNs’ is 42.1, thus being homogenous which is one of the factors for parametric test. The RN sample included 24 subjects while the RPN sample included 31 subjects. This is important to note as even though the RN group had a lesser sample group it showed to have higher scores of knowledge of interpersonal and developmental theory.
Possible sources of error can include type 1 errors in which the null hypothesis was true but it was rejected. Type 1 errors can be reduced by increasing the level of significance. Type 2 errors can result when the sample size is too small and the researcher accepts the null hypothesis when reality it is false. Bias
