Question

12)

Titus has collected a set of data and calculated the median to be 29. The set contains 75 numbers, but Titus gets an email telling him to add the following 6 numbers to his data: 23, 26, 26, 30, 33, 40
What is the new median for his data?
A) 28
B) 29
C) 30
D) 31

Answer 1

29

Explanation:

29 is correct. Since 3 of the new numbers are below, and three are above, 29, the median will not change.

Answer 2

Answer: B

Explanation:

After adding the new data set to the median, we re-arrange in ascending order

23, 26, 26, 29, 30, 33, 40

Median is the midpoint value in the data set, therefore, median is still 29.

I hope this helps.
