1Step 1: Write your hypotheses and plan your research design.
2) Step 2: Collect data from a sample.
3) Step 3: Summarize your data with descriptive statistics.
4) Step 4: Test hypotheses or make estimates with inferential statistics.
5) Step 5: Interpret your results..
The tools include calculators for study design, such as power and sample size calculation, and calculators for data analysis such as t test, chi-square test, Pearson correlation coefficient, linear regression, and receiver operating characteristic (ROC) curve..
Two main statistical methods are used in data analysis: descriptive statistics, which summarizes data using indexes such as mean and median and another is inferential statistics, which draw conclusions from data using statistical tests such as student's t-test..
Statistical tools help with data sorting and cleaning.
They also help to identify and remedy issues with the quality of data through various data cleaning techniques.
It's essential to note that when dealing with large data sets, not all data may be relevant.Sep 30, 2022.
The primary parameters used are the mean (or average) and the standard deviation (see Fig. 6-2) and the main tools the F-test, the t-test, and regression and correlation analysis..

Biostatistics is the exciting field of development and application of statistical methods to research in health-related fields, including medicine, public health and biology..
Data analyzed by biostatisticians assist progress in Epidemiology, the spine of preventive care, and the main component in public health policies.
The biostatistical supervises the link between the reason and effect of the disease or the factors that deal with the wider spread of disease..
The discipline of biostatistics provides tools and techniques for collecting data and then summarizing, analyzing, and interpreting it.
If the samples one takes are representative of the population of interest, they will provide good estimates regarding the population overall.
