Sampling Methods and Statistical Analysis in Survey Research
In conducting research, the primary objective is to analyze a phenomenon and find effective solutions to problems. The process of research involves collecting facts, evidence or results to develop, test or enhance knowledge about natural and social phenomena. Research plays a significant role in advancing science, and it is essential that research findings are made accessible to all.
How to Interpret Negative Coefficient Estimations in Linear Regression?
The ordinary least squares (OLS) method is commonly employed in linear regression analysis to establish the relationship between the independent and dependent variables. Despite its numerous advantages, researchers must meet certain requirements to use this method.
How to Perform Linear Regression using Data Analysis in Excel
Researchers have widely used linear regression analysis to analyze the effect of a variable on other variables. Linear regression analysis consists of the dependent variable and the independent variable. The difference between the two is that the dependent variable is the affected variable, while the independent variable is the influencing variable.
How to use data analysis for sampling in Excel
In research activities, researchers can take samples from the observed population. The purpose of sampling is motivated by time and cost limitations if observations are made on the entire population.
How to use data transformation to address issues with non-normally distributed data
Some quantitative analyzes of parametric statistics require the assumption of normally distributed data. For example, when researchers want to test differences in paired samples using the t-test, researchers need to test the normality of the data.
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 Enable Data Analysis Button for t-test in Excel
Currently, there are many tools available that researchers can use to help analyze research data. Most researchers are more familiar with using excel in manual calculations in data analysis.
