Find the median, first quartile (Q1) and the third quartile (Q3) for the data shown, which is already sorted. The number of data is n= 10. Kate Kozak's algorithm: Sort the data and compute the median. When n is an odd number, the median is the center value. When n is an even number, the median is the center value. After computing the median, Q1 is the median of the 1st half of the data, not including the median value. Q3 is the median of the 2nd half of the data, not including the median value. Do not round your answers. 5.8 9.7 13.4 15.1 18.6 24.9 25.5 27.5 29.6 Median = Q1 = Q3
