Explanation / Answer
GIVEN 175 169 176 172 163 144 152 156
Keeping them in order
144 152 156 163 169 172 175 176
min =144
max =176
median = (163+169) /2 =166
Q1 first quartile is (152+156)/2 = 154
Q3 THIRD QUARTILE IS (172+175)/2=173.5
IR =Q3-Q1 = 173.5-154=19.5
B) The five-number summary for a data set consists of the minvalue, the first quartile, the median, the third quartile, and the maximum value
so the data is
144 154 166 173.5 176
