Biostatistics is an integral part of research protocols. In any field of inquiry or investigation, data obtained is subsequently classified, analyzed and tested for accuracy by statistical methods. Statistical analysis of collected data, thus, forms the basis for all evidence-based conclusions.
The aim of this study is to evaluate the cognition, comprehension and application of biostatistics in research among post graduate students in Periodontics, in India.
A total of 391 post graduate students registered for a master's course in periodontics at various dental colleges across India were included in the survey. Data regarding the level of knowledge, understanding and its application in design and conduct of the research protocol was collected using a dichotomous questionnaire. A descriptive statistics was used for data analysis.
Nearly 79.2% students were aware of the importance of biostatistics in research, 55-65% were familiar with MS-EXCEL spreadsheet for graphical representation of data and with the statistical softwares available on the internet, 26.0% had biostatistics as mandatory subject in their curriculum, 9.5% tried to perform statistical analysis on their own while 3.0% were successful in performing statistical analysis of their studies on their own.
Biostatistics should play a central role in planning, conduct, interim analysis, final analysis and reporting of periodontal research especially by the postgraduate students. Indian postgraduate students in periodontics are aware of the importance of biostatistics in research but the level of understanding and application is still basic and needs to be addressed.
生物统计学是研究方案不可或缺的一部分。在任何研究领域，所获得的数据随后都会通过统计方法进行分类、分析和准确性检验。因此，对收集到的数据进行统计分析是所有基于证据得出结论的基础。
本研究旨在评估印度牙周病学研究生对生物统计学在研究中的认知、理解和应用情况。
共有391名在印度各牙科学院注册攻读牙周病学硕士课程的研究生参与了此次调查。使用二分制问卷收集有关知识水平、理解程度及其在研究方案设计与实施中的应用的数据。采用描述性统计进行数据分析。
近79.2%的学生意识到生物统计学在研究中的重要性，55 - 65%的学生熟悉用于数据图形表示的MS-EXCEL电子表格以及互联网上可用的统计软件，26.0%的学生在课程中将生物统计学作为必修课，9.5%的学生尝试自行进行统计分析，而3.0%的学生成功地自行对其研究进行了统计分析。
生物统计学应在牙周病研究的规划、实施、中期分析、最终分析和报告中发挥核心作用，尤其是研究生。印度牙周病学研究生意识到生物统计学在研究中的重要性，但理解和应用水平仍较为基础，需要加以解决。
