Data Management and Statistics Core

核心C的目标是：（a）便利项目1-4的数据和项目具体数据的获取;（B）开发工具和程序，以确保和监测所有收集到的数据的准确性和保密性;（c）开发工具和程序，以协助主要研究者、执行委员会、和科学顾问委员会提供科学监督和管理得克萨斯州中心的学习障碍，（d）通过最先进的计算机网络促进调查人员之间的沟通和数据共享，（e）提供项目1-4假设的统计分析，以及（f）与调查人员合作构思和开展跨项目，对当前项目的综合分析，以及可能涉及当前项目数据和先前授标时收集的数据的综合分析。大卫弗朗西斯博士，一位经验丰富的方法学家，是核心主任。他将监督核心C的所有活动，与其他经验丰富的方法学家（Stuebing，Cirino，Roberts）密切合作，建立数据库，监督质量控制，并进行统计分析。德克萨斯测量、评估和统计研究所（TIMES）的资源非常广泛，将提供给中心。核心小组有能力进行精密的数据管理和复杂的统计分析，在这方面有着良好的业绩记录。所有项目出版物都反映了过去5年中使用Core C进行数据管理和分析的情况。

The objectives of Core C are to (a) facilitate acquisition of data and project specific data for Projects 1-4, (b) develop tools and procedures for ensuring and monitoring the accuracy and confidentiality of all collected data, (c) develop tools and procedures to aid the Principal Investigator, the Executive Committee, and the Scientific Advisory Board in providing scientific oversight and administration of the Texas Center for Learning Disabilities, (d) facilitate communication and sharing of data among investigators through state of the art computer networking, (e) provide statistical analysis of Project 1-4 hypotheses, and (f) collaborate with investigators in the conceptualization of and to conduct cross-project, integrative analyses from the current projects, as well as those that might involve data from the current projects and data collected in the prior award. Dr. David Francis, an experienced methodologist, is the Core Director. He will supervise all activities of Core C, working closely with other experienced methodologists (Stuebing, Cirino, Roberts) to establish data bases, supervise quality control, and perform statistical analyses. The resources of the Texas Institute for Measurement, Evaluation, and Statistics (TIMES) are extensive and will be available to the Center. The Core has the capacity for sophisticated data management and complex statistical analysis, with an established track record in this area. All of the project publications reflect usage of Core C for data management and analysis over the past 5 years.
