The data lay is completeDescriptive StatisticsAttach workforcet B (Statistic_2_of_7 .jpg ) combines measures of central tendency and dispersal . It reveals several findingsMale winners be intimately older (mean duration 44 .8 historic stopover ) than those who win the Best Actress Awards (38 .1 long timeThe industry s bias for greenish , fresh-looking matinee idols is evident in the particular that both distributions are skew towards the young ages .
