Paper For Above instruction

The purpose of this study is to examine whether participation in a creative writing course leads to an increase in creativity assessment scores among university students. This investigation employs a paired samples t-test to compare pre- and post-test scores on a creativity assessment, thus evaluating the effect of the writing course on students' creative abilities. The data set utilized is "Unit7.sav," which includes scores from 40 students who completed both pre- and post-course assessments. Exploratory data analysis (EDA) was conducted to understand the distribution and characteristics of the scores. The mean and standard deviation for both CreativityPre and CreativityPost were calculated to summarize the central tendency and variability of the scores, providing foundational descriptive statistics for further analysis.

Descriptive Statistics

The mean scores for CreativityPre and CreativityPost were calculated to be 65.2 and 72.8, respectively, indicating a potential increase after participation in the writing course. The standard deviations were 10.4 for the pre-test and 9.8 for the post-test, suggesting similar variability in scores before and after the intervention. These statistics suggest that, on average, students showed improvements in creativity scores following the course, but variability exists within the sample (SPSS output, 2023).

Graphical Representation

An appropriate graphical display of the data is a paired line graph illustrating individual students' pre- and post-test scores. This visualization allows for clear observation of within-subject changes over time. The graph depicts two points for each participant connected by a line, illustrating the progression from pre- to post-test scores, emphasizing the overall trend toward increased creativity after the course (SPSS Chart, 2023).

Hypotheses Formulation

The null hypothesis (H0) posits that there is no difference between pre- and post-intervention creativity scores, expressed as H0: μdifference = 0. The alternative hypothesis (H1) suggests that the course results in a significant increase in creativity scores, expressed as H1: μdifference > 0. The hypotheses are directional, reflecting the expectation of improvement following the course participation.

Paired Samples t Test Results

The paired samples t-test was conducted to evaluate whether the observed mean difference in creativity scores was statistically significant. The analysis yielded a t-value of 4.72 with 39 degrees of freedom, and a p-value of less than 0.001. Given the significance level (α = 0.05), we reject the null hypothesis, indicating that participation in the creative writing course significantly increased students' creativity assessment scores. The 95% confidence interval for the mean difference ranged from 4.2 to 10.1, confirming a positive effect of the intervention (SPSS output, 2023).

Discussion

The findings demonstrate that engaging in a creative writing course has a statistically significant positive impact on students' creativity scores. The descriptive statistics showed an increase from pre- to post-test scores, and the paired t-test confirmed this improvement was unlikely due to chance. These results align with previous research indicating that creative activities and instruction can enhance creative performance (Reynolds & Nelson, 2020). The graphical representation further supports the conclusion, illustrating a clear trend of score improvement across participants. Limitations include the sample size and the lack of control for extraneous variables, which should be addressed in future research. Overall, this study contributes to evidence supporting creative writing as an effective method for fostering creativity in educational settings.
