If the estimated regression coefficient is negative, what does it mean?
Many researchers chose linear regression analysis to reveal how the influence of the independent variable on the dependent variable. Researchers can make estimates using the data they have to interpret the results.
The Relationship between Research Objectives, Analysis Methods, and Hypothesis Testing
Research objectives, analysis methods, and hypothesis testing have a close relationship with one another. Each research objective requires analytical methods to test research hypotheses. On this occasion, Kanda Data will discuss The Relationship between Research Objectives, Analysis Methods, and Hypothesis Testing.
The Effectiveness of the New Learning Method using Paired Sample t-Test
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.
How to Sort the Highest to the Lowest Value in Excel
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.
Correlation Test for Ratio Scale Variables
Correlation analysis is an associative test to determine the relationship between variables. Correlation tests for parametric variables and non-parametric variables are different. Therefore you need to understand how to choose a correlation test according to statistical rules.
How to Write and Test Statistical Hypotheses in Simple Linear Regression
We need to develop hypotheses when conducting research. A hypothesis is a provisional assumption or statement of the research. The hypothesis needs to be proven, whether true or false, through the research process.
