How to Determine T-table and F-table in the linear regression analysis using Excel
Statistical hypothesis testing is an important stage in research activities. Based on the data that has been collected according to the research method used, the next researcher analyzes the data.
How to Find P-Value and T-Distribution Table using Excel
Testing the research hypothesis is an important step that needs to be understood by researchers. Each research objective can be answered through statistical analysis according to the researcher’s chosen analytical method. Therefore, researchers must conduct statistical hypothesis testing properly and correctly.
How to Test Hypotheses in Regression Analysis, Correlation, and Difference Tests
Hypothesis testing is an important step that researchers must test. Researchers will develop research hypotheses according to the points of research objectives. Furthermore, researchers will test the hypothesis using statistical methods so that the test results can be accounted for scientifically.
How to Distinguish 0.01, 0.05, and 0.10 Significance Levels in Statistics
A researcher in planning research will develop a hypothesis from the research that will be conducted. The hypothesis is created as a proposition about the population parameters to be tested statistically through samples taken from the population.
Finding the Best Regression Model Based on R Square
The regression model specification is an important step that researchers must consider. The exact specification will get the best regression model and represent real phenomena well.
Difference between Descriptive Statistics and Inferential Statistics for Research Activities
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.
Understanding the Difference between Parametric and Non-Parametric Statistics
The selection of data analysis methods is an important step that researchers must prepare. The correct analytical method will obtain the proper conclusion.
How to Create and Analyze Variables using a Likert Scale
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.
