Every answer gathered during a study, whether from primary or secondary sources, is subjected to data analysis in order to evaluate the impact of the independent variable on the dependent variable. As a result, data analysis is a critical component of any research and should be understood and performed by all researchers, even university undergraduates. Despite the necessity of data analysis in research, some researchers, particularly university students, find it tiresome and hard to conduct out data analysis on the approach. As a result, the goal of this essay is to lay out a step-by-step strategy to data analysis during research.

What Is Data Analysis And How Does It Work?

Researchers use data analysis to minimize enormous amounts of data and evaluate it in order to get insights. Data analysis is defined as the act of cleaning, transforming, and assessing data in order to uncover relevant information for business decision-making. The data analysis approach assists in the breaking down of a big quantity of data into manageable chunks. However, in order to do data analysis, researchers must first be able to recognize the many types of data that might be acquired during a study. In general, there are three sorts of data:
1. qualitative data    
2. quantitative data
3. quantitative data
3. Categorical data

2. Quantitative data
Qualitative data is information that is expressed in words rather than numbers. Although this information is visible, it is subjective and difficult to analyze in a research, especially for comparison. Everything that conveys flavor, sensation, texture, or an opinion, for example, is considered quality data. Focus groups, personal interviews, and open-ended survey questions are commonly used to acquire this sort of information.

Quantitative data, on the other hand, is information expressed in numerical figures in large quantities. This type of information can be categorized, grouped, measured, computed, or rated. Age, rank, cost, length, weight, scores, and other types of data are all instances of this sort of information. This type of data can be displayed graphically, such as in charts, or it can be analyzed using statistical analytic methods. In surveys, Outcomes Measurement Systems (OMS) questions are an important source of numerical data.
Finally, categorical data is data that is organized into groupings. On the other hand, a categorical data item cannot belong to more than one group. A individual responding a survey by indicating his living

style, marital status, smoking habit, or drinking habit is an example of categorical data. The chi-square test is a popular method for assessing this information.
Data Analysis Processing Steps
After learning about the many sorts of data that researchers collect, it's time to figure out how this data may be analyzed. The actions that may be taken to analyze data are as follows:

Data Validation is the first step.
Data validation, which is divided into four processes, is conducted to assess whether the acquired data sample adheres to the pre-set criteria or is a biased data sample. It's also done to verify that each survey or questionnaire response is recorded by a human. To guarantee that each participant or respondent is selected based on the study criteria. To ensure that ethical guidelines were followed when obtaining the data sample and that the respondent in an online survey answered all of the questions. Aside from that, the interviewer had asked all of the questions on the questionnaire.

Step 2: Editing the Data
A big research data sample is almost always filled with problems. Respondents may fill in some fields incorrectly or skip others by accident. Researchers use data editing to verify that the data they give is error-free. To edit the raw edit and prepare it for analysis, they must complete the necessary checks and outlier checks.

Data Coding (Step 3)
Because it includes classifying and assigning values to survey responses, this is the most critical phase of data preparation. If a survey with a sample size of 500 people is completed, the researcher will create an age bracket to categorize the respondents. As a consequence, rather of dealing with a large data pile, evaluating small data buckets becomes easier.
