Pren recorded this data set, which contains an outlier. 204, 216, 111, 224, 230, 211, 210, 198, 200, 218 What numbers represent the range, lower quartile, and upper quartiles? A. Range: 210.5 lower quartile: 200 upper quartile: 218 B. Range: 14 lower quartile: 111 upper quartile: 198 C. Range: 119 lower quartile: 218 upper quartile: 200 D. Range: 119 lower quartile: 200 upper quartile: 218
Accepted Solution
A:
Range = highest number - lowest number...so the range is 230 - 111 = 119
to find the quartiles, we have to put the numbers in order... 111,198,200,204,210,211,216,218,224,230 Q1 ...lower quartile = 200 <=== Q2 ...the middle number = (210 + 211) / 2 = 421/2 = 210.5 Q3...upper quartile = 218 <===
