B is the true true upper inner fence false balance line false H-spread false outside line boxplotqa.gif Upper inner fence. It is one step above the upper hinge. The H-spread is: true false C-H true D-G false E-F boxplotqa.gif The H-spread is the difference between the upper hinge (D) and the lower hinge (G). Which of the following is/are true? true false The median is higher than the mean. false There is one far out value. true The lowest value is H. There is an outside value, but no far out value. false The highest value is C. boxplotqa.gif The lowest value is H. Box plots are preferable to stem and leaf displays when true true there is a large amount of data. false it is important to show individual data values. true three or more groups are to be compared. false the distribution is skewed. The two correct choices are (1) There is a large amount of data and (3) when more than three groups are compard. Stem and leaf displays show individual values and skew well.
