The box plot with the horizontal axis contains the markings “B R O” and “B R O P S O” from left to right. The vertical axis of the graph is labeled “Cost Function”, and ranges from 345 to 375 with an increment of 5 units. The data values in the bars are as follows: B R O: Lower Quartile: 366. Median: 368. Upper Quartile: 374. Minimum: 366.5. Maximum: 372. B R O P S O: Upper Quartile: 349. Minimum: 347. Maximum: 348.5. Note: All numerical data values are approximated.Chart box of solved 8 m castellated beam. Source: Authors' own work
