In the data set below, what are the lower quartile, the median, and the upper quartile?
13555678999
lower quartile =
median =
upper quartile
To find the lower quartile, median, and upper quartile of the data set 13555678999, we first need to arrange the numbers in numerical order:
1, 3, 5, 5, 5, 6, 7, 8, 9, 9
Now we have:
Lower Quartile (Q1) = The median of the lower half of the data set = 5
Median (Q2) = The middle value of the data set = 6
Upper Quartile (Q3) = The median of the upper half of the data set = 8
Therefore, the lower quartile is 5, the median is 6, and the upper quartile is 8.
