Question

ou think that there may be differences in compliance rates among hospital units. You look at the average medication barcode scanning rates for nursing staff in med-surg units, step-down units, and critical care units. Question: Is there a difference in the barcode scaning rates by type of hospital unit?

What is the most appropriate test to statistically test this hypothesis? Why?

State your null and alternative hypothesis in words and symbols.

Answer 1

• The most appropriate test to statistically test this hypothesis one way Anova

Because when we conduct Statistical differences among the means of two or more groups are carried out then we use  one way Anova

.So in the given question  difference in the barcode scaning rates by type of hospital unit ( med-surg units, step-down units, and critical care units ) three groupe are there so one way Anova is   appropriate test

Null hypothesis ( H0 ) : there is no difference in the barcode scaning rates by type of hospital unit

i.e .,

Alternative hypothesis ( H₁ ) :   there is no difference in the barcode scaning rates by type of hospital unit

i.e., Not all the means are equal
