How to use biostatistics
The application of biostatistics in the thesis was as follows: ** 1. Research and design ** 1. ** Confirm reasonable sample size ** - The appropriate sample size was determined based on factors such as the purpose of the study, the overall characteristics, and the expected statistical power. For example, in clinical trials of drugs, if the sample size was too small, it might not be possible to accurately detect the difference in efficacy of the drugs, and if the sample size was too large, it would cause a waste of resources. 2. ** Design research proposal ** - The type of research planned, such as experimental research (such as a random controlled trial) or observational research (such as a cohort study, case-control study, etc.). Different types of research were suitable for different methods of analysis, and a reasonable research design was the basis for subsequent accurate analysis of data. ** 2. Data Collection and Sorting Stage ** 1. ** Choice of Data Collection Method ** - Biostatistics could guide the selection of appropriate data collection tools and methods to ensure the accuracy and integrity of the data. For example, when investigating the incidence of a certain disease, it was necessary to clarify the criteria for the subjects to be included and excluded, as well as how to accurately record the relevant symptoms, signs, and other data. 2. ** Data Collate ** - The collected data was categorized, codified, and entered. For example, the patient's age, gender, and other demography data, as well as various physiological indicators, were organized into a format suitable for statistical analysis, and the data was checked for missing values or errors. ** 3. Data Analysis Stage ** 1. ** Choose a suitable method of statistics ** - According to the purpose of the study, the type of data (such as quantitative data, qualitative data), and distribution characteristics, the corresponding statistical methods were selected. - For the comparison of two sets of quantitative data, if the data satisfied the normal distribution and had the same variation, the t-test might be selected; if it was a comparison of multiple sets of quantitative data, the analysis of variation might be used. For the analysis of qualitative data, methods such as the Chi-square test might be used. - When studying the relationship between variables, such as the relationship between height and weight, one could use a regress analysis. 2. ** Data Mining and Model Building ** - When dealing with a large amount of complex biological data (such as gene expression data), biostatistics methods were used for data mining to construct appropriate statistical models. For example, constructing a logistic regress model to predict the risk of disease occurrence, by analyzing the relationship between multiple risk factors and the occurrence of the disease, the prediction model was obtained and the accuracy of the model was evaluated. ** IV. Interpretation of the results and thesis writing ** 1. ** Interpretation of the results ** - Biostatistics experts could extract meaningful information from the results of the analysis and explain the significance of the results. For example, a p-value of less than 0.05 indicated that there was a significant difference in statistics. However, the significance of this difference in practice needed to be explained in combination with biological background knowledge, such as whether the difference in efficacy between a certain drug treatment group and a control group had clinical value. 2. ** Thesis Writing ** - In the results section of the thesis, accurately report the results of the statistics analysis, including the values of statistics (such as t-value, F-value, etc.), p-value, confidence intervals, and so on. In the discussion section, the research hypothesis was verified according to the statistics, and the significance, limitations, and implications of the research results were explained.
