Find the five-number summary of the following set of numbers.?

Question

337, 248, 157, 388, 248, 451, 271, 225, 310

Answer 1

First put them in order:
157, 225, 248, 248, 271, 310, 337, 388, 451

The first number is now 157; the last 451

The median is the middle number: 271

The lower quartile is the median of the numbers below the data median; that's 1/2 way from 225 to 248 or 236.5

Similarly, the upper quartile is 1/2 way between 337 and 388 or 362.5

So your 5 number summary is 157, 236.5, 271, 362.5, 451

Hope that helps
