Find the value of Q1 for this data:
2,4,6,8,10,12,14
A. 4
B. 5
C. 8
D. 12
Q1 refers to the first quartile, which divides the data into the lowest 25%. To find Q1, we need to calculate the median of the lower half of the data.
The lower half of the data includes 2, 4, and 6.
To find the median of this set, we find the middle value, which is 4.
Therefore, the value of Q1 is 4.
