Abstract
Due to the varied nature of museums, measuring experiences of young visitors particularly on generic learning outcomes are challenging. Thus, in order to ensure the data of experiences of visitors in museum is normal, this study aimed to evaluate possible violation of the normality assumptions in the data sets. A combination of graphical inspection, assessment using skewness and kurtosis, and formal normality tests were used to assess whether assumption of normality is acceptable or not. Data sets obtained from questionnaire surveys were used to demonstrate the changes from non-normally distributed data sets to relatively normally distributed data sets by removing abnormal data. It is concluded that all the data seem to satisfy the assumption of normality, therefore, the data sets can be used for further statistical tests.
