Using Hands-on Experiences including Various Forms of ARTS to Increase Ninth-Grade Female Students’ Interest in STEM – Final Results c) Inferential Statistics Analysis Inferential statistics are used to make assumptions about an entire population based on sample data. For example, using the preliminary data from the survey of 9th-grade female students, we can conclude about the whole 9th-grade female population. Comparing the data to the post-survey data can clarify the hypotheses' validity. To interpret ordinal data, it is best to utilize non-parametric procedures. Non- parametric tests are performed using the median, making them ideal for ordinal data. Non-parametric analysis can be conducted using the Mann-Whitney, Wilcoxon, Kruskal Wallis, and Friedman tests. The survey's preliminary data is summarized in the chart following the intervention. It is important to note that the data is obtained from a smaller sample size. However, the participants remain 9th-grade female students. The corresponding descriptive statistics are compiled into the following tables for secondary visual analysis. The preliminary data also uses ordinal data descriptive statistics such as median, mode, range, and interquartile range.
