No general consensus exists amongst qualitative researchers concerning the process of data analysis. Statistical analysis is a study, a science of collecting, organizing, exploring, interpreting, and presenting data and uncovering patterns and trends. The distribution of data is important to measure. The sole purpose of research methods is to find the solution. Many businesses rely on statistical analysis and it is becoming more and more important. Statistical analysis in this tradition is guided by and dependent on all the previous steps of the research process, including the level of knowledge development, research problem, research question, study design, number of study variables, level of measurement, sampling procedures, and sample size. 10.7.
