And yet, significance testing is not the only issue, and the present focus is on two other issues where the central limit theorem does not come to the rescue. First, there is the question of how well the sample location statistic estimates the population location parameter. Surprisingly, skewness increases the precision of the estimation, and this increase in precision is impressive even with very low levels of skewness. Thus, by ignoring low levels of skewness, researchers are throwing away an important advantage. Second, experimental manipulations can cause differences in means across conditions, when there is no difference in locations across conditions; so the experiment seems to have worked based on means, when it really has not worked based on locations. Thus, moderate effect sizes can be caused by slight changes in skewness. For both reasons, it is recommended that researchers always attend to skewness, even when it is slight; and consider locations whenever they consider means.","PeriodicalId":173443,"journal":{"name":"International Journal of Aviation Research","volume":"160 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115995445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The report comes from the National Center for Educational Statistics stating that enrollment increased from 13.2 million to 16.9 million peaking at 18.1 million in 2010 (McFarland, et al., 2018). Over the last decade, graduate student enrollment across the Unites States has been increasing significantly (Okahana & Zhou, 2017). According to the 2017 report from the Council of Graduate Schools (CGS), graduate applications increased on average at a rate of 5.7% from the years spanning 2006 to 2016 (Okahana & Zhou, 2017). The report also enumerated the increase in graduate degrees awarded and conferred between 2006 and 2016. In the span of that decade, doctoral degrees conferred within the United States increased at an average rate of 4.7% per year and master’s degrees awarded increased at an average rate of 2.4% (Okahana & Zhou, 2017). The number of master’s degrees awarded is of course far in excessive of the number of doctoral degrees conferred but the percentages show a larger increase in the rate of growth of doctoral degrees.","PeriodicalId":173443,"journal":{"name":"International Journal of Aviation Research","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131494564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
