Why is Descriptive Statistical Analysis Important?
When you are completing your final project as a student, you will usually find descriptive statistical analysis results in one of the chapters. It can be seen in a separate sub-chapter or part of one of the chapters written in the thesis. For example, sub-chapters have used descriptive statistical analysis in economics and agribusiness research. Therefore, I will choose this topic to discuss.
Choosing Simple Random Sampling in Conducting Research
Simple random sampling has often been used by researchers when determining the sample. In this case, the researchers chose a random sample. Researchers who choose this technique must meet the required assumptions. Incidentally, on this occasion, I will discuss the topic of simple random sample selection techniques.
Comparison of Two Sample Dependent (Paired t-test)
The comparison of two paired samples becomes interesting to discuss this time. This two-sample comparison test is often analyzed using a paired t-test. Many researchers or students who are conducting research choose to use this test.
How to Compute Spearman Rank Correlation Test
A correlation test is still often an option to solve problems in research. The correlation test includes the Pearson correlation test, Spearman rank correlation test, and chi-square test. Determining the type of correlation test to use depends on the measurement data scale. Well, on this occasion, I will discuss using the Spearman rank correlation test.
Autocorrelation Test on Time Series Data using Linear Regression
The autocorrelation test is one of the assumptions of linear regression with the OLS method. On this occasion, I will discuss the autocorrelation test on time series data. Before discussing the autocorrelation test, you need to know first that the autocorrelation test was conducted on time series, not cross-sectional data.
Regression Assumption Test: How and Why to Do?
Incidentally, the topic that I will discuss this time is the linear regression assumption test using the ordinary least square method. “Why do we have to use the linear regression assumption test? Can I directly do a regression analysis?” To answer this question, you need to go back a little bit by turning page after page from a book on econometric theory or socio-economic statistics, okay? One of the main points that you need to pay attention to is that you are doing an estimate when you analyze research data and then choose regression as an analysis tool.
Hypothesis Test for Regression and Correlation Analysis
Do you still remember the term hypothesis? The hypothesis is a temporary conclusion from the research results that will conduct. You can also state that the hypothesis is a preliminary answer from the research results based on our presumptions. In this article, I will discuss the Hypothesis Test for Regression and Correlation Analysis on this occasion.
How to Write an Abstract of an Article for Publication in a Scientific Journal
Skills in writing articles, nowadays are increasingly needed. A researcher is not only required to be able to produce novelty in research activities but also needs skills to convey research results in written form. Although the research results have important benefits for the world of science, if the research results do not reach the intended users, the delivery of the research results can be hampered.
