Question #31043
In a study on survival time for twenty patients following a new treatment for Aids, the time in months was 19 24 12 8 20 23 22 16 15 24 27 25 24 18 3 21 10 9 26 25. Determine the mode for the given data.
a. 48
b. 32
c. 36
d. 24
a. 48
b. 32
c. 36
d. 24
Expert's answer
The mode is the score that occurs most frequently.
The time in months was 19 24 12 8 20 23 22 16 15 24 27 25 24 18 3 21 10 9 26 25[Original data set].
Ordering the number of months from least to greatest, we get:
3 8 9 10 12 15 16 18 19 20 21 22 23 24 24 24 25 25 26 27 [Arrange in order].
24 occured three times and no other score occured more than two times.
The time which occurs most often (the mode for the given data) is 24.
Answer: d. 24.
