Case Study
A researcher wanted to answer the following question: What is the difference in students' computer anxiety based on whether or not they own computers? The researcher surveyed 92 undergraduate education students via an online survey. In the survey, the researcher asked a yes-or-no question to determine if students owned computers.
Participants' computer anxiety was measured using the Computer Anxiety Scale. Scores ranged from 0 to 40 with higher scores reflecting greater computer anxiety. This variable was measured on the interval scale. The researcher analyzed the data using what t test?

Introduction
Understanding the differences in computer anxiety among college students based on their ownership of computers is vital for informing educational strategies and technological support programs. The central research question in this study concerns whether there is a statistically significant difference in computer anxiety scores between students who own computers and those who do not. A proper statistical test, appropriate to the data and the research design, must be conducted and meticulously reported in APA style, accounting for assumptions and descriptive statistics.
Methodology
The study involved 92 undergraduate students enrolled in education courses. Participants completed an online survey that included a yes/no question regarding computer ownership. Subsequently, they completed the Computer Anxiety Scale (CAS), which measures levels of computer anxiety on an interval scale from 0 to 40, with higher scores indicating greater anxiety. Since the research compares two independent groups—students who own computers versus those who do not—the appropriate statistical test is an independent samples t-test, which compares the means of two unrelated groups.
Results
Assumption Tests
Prior to conducting the t-test, assumptions of normality and homogeneity of variances were checked. Normality of the CAS scores for each group was assessed using the Shapiro-Wilk test; assuming the tests indicated normality (p > .05). Homogeneity of variances was tested using Levene’s Test; if Levene’s p-value was greater than .05, equal variances were assumed. Any violations of assumptions should be noted, but the most appropriate t-test should be performed regardless.
Descriptive Statistics
Descriptive statistics, including means and standard deviations, were calculated for both groups. For example, students owning computers (n=X) had a mean CAS score of M1 (SD1), while students not owning computers (n=Y) had a mean CAS score of M2 (SD2).
Null Hypothesis
The null hypothesis (H0) posits that there is no difference in computer anxiety scores between students who own computers and those who do not.
T-test Results
The independent samples t-test was conducted. The results indicated a t-value of T with degrees of freedom df. The p-value associated with this t-value was p. Since p is less than or greater than 0.05, the decision was to reject or fail to reject the null hypothesis.
Conclusion
Based on the analysis, it can be concluded that there is/ is not a statistically significant difference in computer anxiety between students who own computers and those who do not. This suggests that computer ownership may/may not influence levels of computer anxiety among undergraduate students.
