Question

Here are the weights, in pounds, of 13 deer tagged in a park.

186 171 219 190 130 189 214 135 168 183 175 170 190

Which data values are outliers?

Choose all answers that are correct.

130

135

214

219

Answer 1

below 139 and above 220
My answers are 130 & 135

Answer 2

Original data:

186, 171, 219, 190, 130, 189, 214, 135, 168, 183, 175, 170, 190

In ascending order:

130, 135, 168, 170, 171, 175, 183, 186, 189, 190, 190, 214, 219

Minimum: 130
Median 183
Maximum: 219
1st quartile: 169
3rd quartile: 190
IQR: 21
1.5 * IQR = 31.5
169 - 31.5 = 137.5
190 + 31.5 = 221.5
The oultier boundaries are 137.5 and 221.5, so points outside the boundary range are outliers.

Answer 3

Your final answer is correct, although I didn't get the same outlier boundaries you did.

Answer 4

what did you get

Answer 5

Thanks @mathstudent55

Answer 6
