In the data set below, what are the lower quartile, the median, and the upper quartile?
1246889
lower quartile =
median =
upper quartile =
To find the lower quartile, median, and upper quartile of the data set 1246889, we first need to sort the numbers in ascending order:
1, 2, 4, 6, 8, 9, 12
The data set has 7 numbers, so the median is the middle number, which is 6.
To find the lower quartile, we take the median of the numbers below the median. In this case, the numbers below the median are 1, 2, and 4, so the lower quartile is the median of these numbers, which is 2.
To find the upper quartile, we take the median of the numbers above the median. In this case, the numbers above the median are 8, 9, and 12, so the upper quartile is the median of these numbers, which is 9.
Therefore, in the data set 1246889:
Lower quartile = 2
Median = 6
Upper quartile = 9
