NAMEProfessor ____________COURSE4 December 2007The Ages of Oscar Winners : A Statistical AnalysisSummary StatisticsAttachwork forcet A (Statistic_1_of_7 .jpg ) try outs the marginal stem for the data , a two-way frequency give in that scarce lists all the records included but broken down by gender . Because it is unsorted , all we can tell from this table is that all 78 Oscar winners atomic number 18 accounted for in the data dethaw . The data set is completeDescriptive StatisticsAttach workforcet B (Statistic_2_of_7 .jpg ) combines measures of central tendency and dispersal . It reveals several findingsMale winners are intimately older (mean age 44 .8 historic period ) than those who win the Best Actress Awards (38 .1 long timeThe industry s bias for unripe , fresh-looking matinee idols is evident in the particular that both distributions are skewed towards the young ages . The majority of winners are in fact jr. than the above average ages would suggestThis is demonstrated by the fact that the median age for Best Actor recipients is 1 .8 years disgrace than the mean . That is , half of all anthropoid winners were 43 years or junior . And the selected mode - the age at which thither are many more potent winners than others - is distinctly junior , at 32 yearsThe disparity is even greater for the ladies . starting line of all , the standard error of the mean for them (2 .141 years ) is wider than it is for the men (1 .62 years . This already tells us that we are on shakier demonstrate if we boldly proclaim that , the recipients of the Best Actress Oscars are usually or typically 38 years old . In fact , half of the women winners were 34 years old or younger when they won .

And the displayed modal value of 26 years would ordinarily have us conclude that more often than not , women winners were in their mid-twenties or six years younger than is suggested by the modal value for the menSimple analysis of the clutches , the stripped and maximum ages , already tells us a great have it off . Female winners have historically spanned a wider age range (as young as 21 , as old as 80 . For the men , the range has been considerably narrower . While the oldest male winner approached the upper limit for the women (76 years , no male lead received an Oscar before reaching 31 years of ageThis wider dispersion is also shown by the fact that the variance is considerably greater for the women (178 .7 ) than it is for the men (102 .5Thirdly , the standard deviation values show that if these distributions were truly normal curves (they are not , 68 .26 of the men would fall within a narrower age span (ages 34 .7 to 54 .9 , a years ) than is true for the women (ages 24 .7 to 51 .5 or a span of 26 .7 years . So we discern that the Academy of Motion Picture Arts and Sciences are as amenable to honoring performances by middle-aged actresses as they are to awarding those...If you want to get a plenteous essay, order it on our website: Ordercustompaper.com
