‘Association of demographic variables versus frequency of use of core aerospace engineering e-Databases’: a research survey of aerospace scientists and engineers of Bangalore

Abstract

Demography is the scientific study of characteristics and dynamics pertaining to the human population, including things like size, growth rate, density and distribution of a specified group. The primary reason people use demography is to create statistics--in fact, the term roughly translates to "people measurement." These allow a person to get a picture of how common specific traits within a group are. Comparing statistics over time also allows researchers to show changes that are happening in the target group. A research survey was undertaken to ascertain the ‘Association of Demographic Variables versus the Frequency of Usage of Core Aerospace Engineering e-Databases’ amongst the aerospace scientists and engineers of selected 16 aerospace organizations of Bangalore. The major findings of this study are: The c2 test indicates that the demographic variable, viz., Category Wise Distribution of the Respondents, namely: Aerospace Scientist / Aerospace Engineer(c2=20.832, P Value = 0.000), Occupation(c2=65.978, P Value = 0.000), Qualification(c2=28.207, P Value = 0.005), and Specialization(c2=42.228, P Value = 0.003), by the ‘Frequency of Use of Core Aerospace Engineering e-Databases’ have significant association. This implies that the percentage of preference for the above mentioned demographic variables are not approximately the same [Not Uniformly distributed]. The c2 tests for the remaining demographic variables, namely, Gender and Age-Group by the ‘Frequency of Use of Core Aerospace Engineering e-Databases’ have no significant association. This implies that percentages of preference for these demographic variables are approximately the same [Uniformly distributed].
