question 6

Multiple Choice

You are trying to determine if there is a significant difference in the mean Glasgow coma scale score for patients who are seen with a head injury during the day, evening and night shifts in your emergency room. Your ANOVA results have an F value of 22.33 and a p value of <0.01. You know this means:

• A) There is a significant difference in the mean Glasgow coma scale score for patients seen with a head injury on the three different shifts.
• B) There is NOT significant difference in the mean Glasgow coma scale score for patients seen with a head injury on the three different shifts.
• C) A type I error was made.
• D) A type II error was made.
