Glove Use Among Nurses
Data from an experiment to see how an educational program on the importance of using gloves affected the rate of glove use by a group of nurses in an inner-city pediatric hospital emergency department. Without their knowledge, the nurses were observed during vascular access procedures before and one, two, and five months after an educational program to see how often they wore gloves. Each procedure by a nurse was counted as a separate observation. Missing values are indicated by large dots. Number of cases: 23 Reference: Friedland, L., Joffe, M., Moore, D. , et al.

Improving Reading Ability
Results of an experiment to test whether directed reading activities in the classroom help elementary school students improve aspects of their reading ability. A treatment class of 21 third-grade students participated in these activities for eight weeks, and a control class of 23 third-graders followed the same curriculum without the activities. After the eight-week period, students in both classes took a Degree of Reading Power (DRP) test which measures the aspects of reading ability that the treatment is designed to improve.

Percent of a Standard 50-word list heard correctly in the presence of background noise. 24 subjects with normal hearing listened to standard audiology tapes of English words at low volume with a noisy background. They repeated the words and were scored correct or incorrect in their perception of the words. The order of list presentation was randomized. The word lists are standard audiology tools for assessing hearing. They are calibrated to be equally difficult to perceive. However, the original calibration was performed with normal-hearing subjects and no noise background. The experimenter wished to determine whether the lists were still equally difficult to understand in the presence of a noisy background. Number of cases: 96 Reference: Loven, Faith. (1981).
