Solve for the interquartile range. Upload your plot for your teacher to review. Ok, so I know how to construct a boxandwhisker plot, I just want to make sure that I have solved for the interquartile range correctly. This is the formula for interquartile range: IQR= xuxl I am thinking, from the data, that the upper quartile would be 60 and the lower quartile would be 34. Am I correct in assuming that the minimum is the lower quartile and the maximum is the upper quartile? I guess that is my main question here. So, I have done: IQR=6034 IQR=26 Did I do this correctly? Thanks!
