Question: Length of Home Health Visits and Time of Day

The nursing supervisor in a local health department wished to study the influence of time of day on length of home visits by the nursing staff. It was thought that individual differences among the nurses might be large, so the nurse was used as a blocking factor. The nursing supervisor collected the following data:

Data File: Nurse Visit.

a) Conduct an appropriate test to determine if the mean length of visit is related to the time of day. Summarize your findings. (4 pts.)

b) Conduct multiple comparisons to compare the mean lengths of stay between the different times of the visits. Also examine CI’s for the differences in means. Summarize your findings. (4 pts.)
