# Things every researcher should know about Regression analysis, Correlation and ANOVA: An ultimate guide for statisticians

0

Regression analysis is used to measure and analyse data trends and patterns. Quantitative data is easy to analyse and evaluate. The research design of the quantitative research method assists the calculation process. Research design can have qualitative research or quantitative research design. A researcher may also use an integrated research method. The integrated research method incorporates both methods. It is challenging to conduct quantitative research as the data calculation, and interpretation in this process are challenging.

The research conducted via statistical methods helps identify trends:

• Statistical measurement inaccurate decision making becomes precise.
• The advancement in information and communication technology resources is bringing development.

## Statistical Analysis:

The statistical process calculates the relationship with the use of quantitative statistical material. This research process is being used in various dimensions, including business, education, government, scientists, and many other fields. The statistical analysis helps the researcher to draw a solid conclusion. The researcher needs careful observation and calculation from the first step.

The first step of statistical data analysis is to specify the research hypothesis. The researcher needs to structure the research. The researcher should select participants, the researcher, and the sampling mechanism. Measuring variables are a critical part of statistical analysis. This article will explain three variable measuring tools:

1. Regression analysis
2. Correlation
3. ANOVA

After data collection, the researcher needs to organise data presentably. The following statistical analysis step is to summarise the data. Summarise with the help of descriptive statistical analysis. The researcher may use the tool of inferential statistics. These formal inferential statistical tools can conduct a hypothesis test. It may also help in estimating the population segment. In the final stage, the researcher can make effective interpretations and results from the findings.

## Tools for Measuring Variables

The researcher in their research draft should be aware of their data type. The research data type can be qualitative or quantitative data. Moreover, the researcher needs to use the most appropriate tools and techniques. The selection of an accurate measuring tool may help the researcher get authentic results. These results are based on the analysis of the raw data.

### Regression analysis

Regression analysis is one of the most commonly used statistical measuring tools. It may be utilised in different studies, including physical, behavioural and social studies. It helps to evaluate the relationship between different variables. Two variables are independent and dependent. The dependent variable depends on the independent variable.

Regression analysis helps the researcher to analyse different variables. The regression process leads to determining the influential variable. It also helps build a relationship between the factors that may influence each other.

The research hypothesis will determine the dependent and independent variables of the study. The data collection mechanism will lead the researcher to collect raw data. This data may be collected from the participants of the study. Regression analysis will help evaluate the relationship or patterns between the two or more different variables.

### Correlation

Correlation is a variable measuring tool. This tool helps the researcher study and evaluates two or more variables. These variables include dependent and independent variables. Correlation draws a relationship of fluctuation or change among different variables via the correlation coefficient. In this way, the researcher can find the change observed among different variables. A positive correlation value reflects that the variables remain parallel to each other. The positive correlation value reflects the different phases and circumstances of the study. A negative value in the correlation analysis reflects that the variables act differently during different phases. The fluctuation of equal intensity reflects that the variables have a connection. That relationship among variables is dependent and independent variables. Measuring the correlation tool helps the researcher find the relationship between variables.

### ANOVA

ANOVA is a term that stands for ANalysis Of Variance. The ANOVA analysis tool is used among dependent and independent variables. It helps to understand single or multiple independent variables studied with dependent variables. For instance, an independent variable can be the affiliation with a political party. The dependent variable in this example may be the public attitude toward a tax deduction. During the twentieth century, the statistical tests of t and z-test methods were developed. These tests remained in practice till 1918. Ronald Fisher designed a variance method that distracted people from the t-test and z-test.

#### Uses in Statistics

Each statistical result and measuring tool provides some values. These values may help determine whether the null hypothesis statement is valid. The analysis and evaluation mechanism reflects the combination and contrast among variables. The variables involved in the article are part of measuring tools. This way, the researcher will be able to analyse the significance of the study. Hence researchers can draw clear conclusions based on these statistical measuring tools. The ultimate purpose of any research work is to prove or disapprove of the null hypothesis. A research hypothesis statement contains dependent variables and independent variables. The statistical data measuring tools help the researcher build relationships. These relationships are between different variables in the hypothesis statement. The researcher will be able to draw a relationship between different variables. This relationship or pattern will help approve or disapprove the hypothesis statement.

## Conclusion

The ultimate purpose of the research is to reach a solid and definite conclusion. In this manner, the researcher needs to construct the research design. The research design should also contain the topic of the study. The researcherâ€™s questions should also be the part of research design. Moreover, the research hypothesis statement of the study should be the part. The approval and disapproval of the null hypothesis are the results of any studies. Therefore, the researcher needs to measure different variables using any statistical measure tools. These tools include Regression analysis, correlation, and ANOVA measuring tools.
