Summary

The webpage focuses on data preparation and analysis. It divides the topic into five subsections which include data preparation, descriptive statistics, correlation, inferential statistics, and statistical significance. Data preparation section outlines the significance of organizing data correctly for analysis (Agresti, 2018). It emphasizes on the accuracy of the data entered through the use of spot-checking or the use of specialized computer programs. The second subsection which is the descriptive statistics focuses on the description of the data without concluding. Descriptive statistics entails the central tendencies, the distribution, the range, and many other aspects of data that would help in drawing meaningful meaning conclusions (Silverman, 2018). The third subsection focuses on the correlation which is one of the most often used kinds of descriptive statistics. Correlation describes the degree of relationship between two variables. The fourth subsection is about the inferential statistics that allows the researchers to make inferences on the data collected based on the hypotheses (Zhang, Zhang, & Yang, 2003). The fifth section focuses on the statistical significance on which the conclusion of any research proposal should be based. The data preparation and analysis section focus on the key areas that must be considered in any given research to achieve the desirable results (Unite for Sight, 2019). However, it does not include the step by step procedure that needs to be followed to achieve the required results.
