The following is the abstract of a paper entitled Examination of Abstract Writing Styles. Analyze the abstract and tell the function (such as background inf., or any other function ) of each part (numbered from 16) Examination of Abstract Writing Styles Abstract (1)In view of the U.S university student abstracts, there is an urgent need to shed light on their writing styles. (2)This paper aims to examine the abstract writing styles written by university students majoring in physical sciences. (3) A large sampling of abstracts, i.e. 2,460 university student abstracts, was obtained from across the United States, among which 40 university students majoring in physical sciences were selected. Different statistical methods were carried out: analysis of variance and least squares fit of percent errors as against program level approach. (4)As a result, the findings from the table style led to the conclusion that southern universities tended to use more verbose style while northern universities tended to adopt more cryptic style. (5)Moreover, interesting conclusions of the correlation study were drawn: Students whose parents were below the "poverty level" showed intermediate writing skills at the freshman level but improved more quickly with time ending with MS or PhD levels; on the other hand, students with parents above poverty level showed initial advanced writing skills and slowly improved to the professional level at the MS or PhD levels. (6)Also recommendations are made, such as preparing students at the high school level in basic writing skills under state educational systems and setting up technical writing course mandatory for science or engineering university students at the junior level.
