The effectiveness of a new method can be tested using paired sample t-test. The paired sample t-test was chosen due to using the same sample before and after using the new method.
Research data need to be analyzed to obtain the required information. We can choose various data analysis techniques according to the purpose of data analysis.
In research activities, researchers need to understand the use of descriptive statistics and inferential statistics. Researchers can use one of them or combine both descriptive and inferential statistics.
The selection of data analysis methods is an important step that researchers must prepare. The correct analytical method will obtain the proper conclusion.
In statistics, research variables can be measured in parametric and non-parametric variables. Variables measured by interval scale and ratio scale are grouped in parametric variables.
