TESTLET F
Dental hygiene students from a local program visit a geriatric day care called Camp Sunshine to implement a service learning project. These campers are functionally independent, although they are medically compromised. Under faculty supervision, the students screen the seniors to identify denture cleanliness and teach them how to clean their dentures daily. The goals are to improve their oral health by cleaning their dentures or partial dentures, increase their awareness of the need for daily oral care, and empower them to clean their dentures. The students compute the mean scores of the denture cleanliness measure for future evaluation of the program outcomes.
-To evaluate the success of the program, the students return in 6 months to measure denture cleanliness. What statistic would be used to compare the mean baseline and post-test scores of denture cleanliness?

A) Analysis of variance (ANOVA)
B) Chi-square
C) Correlation coefficient
D) t test
