For the record, at this time, Kean University students and faculty do not have access to any qualitative data analysis software. However, there are opportunities for free trials or occasionally a deeply discounted licensing fee for students for the programs listed above.
Data Coding - Cycle I
There are several steps in the first cycle of coding. The first thing you need to do is to immerse yourself in the transcript data. Read the data. Read it again. Then, read the data again. Do this several times, and as you do so, you will start to get a sense of the data as a whole. Start annotating in the margins, “chunking” data into categories that make sense to you. This step is your very first preliminary pass at coding. As you do the “chunking,” read over the chunks and see if you start to identify patterns or contradictions. Some really excellent guides and resources for you as you begin your coding process are:
The Coding Manual for Qualitative Researchers, 4th edition - Johnny Saldana (2021)
Qualitative Data Analysis: A Methods Sourcebook, 4th edition - Matthew Miles, Michael Huberman, & Johnny Saldana (2020) Both of these books are held by Kean University's Library.
Code book is a manual of all the codes that you use. A code book identifies and defines code names and explains the protocol for what data is included and what data is not included. You will begin with 25-35 codes. As you move through the cycles of analysis, your codes will be combined into categories and then themes. |
If you are using a data analysis software tool, you will be able to do each set of coding cycles within the program. Essentially, the steps and processes are the same as if you are coding by hand. The process for each software cycle will vary depending on the program. |
Data coding - Cycle II
During your second cycle (and third, if need be) of coding, you start clustering chunks of data that have similarities. As you are doing this, you are reading over the chunks of data, refining your code book, and narrowing down the scope of each code. You will go through 2 or 3 cycles of narrowing down codes, grouping them together, and winnowing down the data. You will most likely move from 25-30 codes to grouping them together in clusters to develop themes. These themes are the core of your data analysis. You will end up with 5-7 central themes that tell the story across the data (Saldaña, 2021). Kinds of Coding
As you work your way through the data analysis, you will be going through three different kinds of coding as you progress (Miles et al., 2018; Bogdan & Biklen, 2007; Creswell & Creswell, 2018):

The term “data analysis” can be a bit misleading, as it can seemingly imply that data analysis is a single step that’s only conducted once. In actuality, data analysis is an iterative process. And while this is obvious to any experienced data analyst, it’s important for aspiring data analysts, and those who are interested in a career in data analysis, to understand this too.
Want to learn more about the data analysis process and how it’s used? Then you’re in the right place. Below, we’ll tell you all about the data analysis process, the different steps of the process, how data analysis is used, and how to do it the right way.
Ready? Then let’s get started!
Data analysis starts with identifying a problem that can be solved with data. Once you’ve identified this problem, you can collect, clean, process, and analyze data. The purpose of analyzing this data is to identify trends, patterns, and meaningful insights, with the ultimate goal of solving the original problem.
There is indeed a specific process for data analysis. Suppose you are looking to create the best recipe for pizza dough. You could frame your problem as a lack of knowledge—not having a sufficient pizza dough recipe.
What data could help you solve this problem? One way would be to comb through the plethora of online recipes available. You could then sort this data, filtering out recipes with low reviews or comments noting flaws in the recipe. Then, once you’ve collated the best recipes, you can begin to analyze them. What are the commonalities that emerge? Maybe you find that the best recipe depends on the style of pizza you want to make and that it’s best to group certain recipes together. The data analysis process won’t create the perfect pizza dough recipe for you, but it can get you headed in the right direction.
Let’s take a more in-depth look into the data science process:
This is arguably the most critical step, as it can set you up for success. The purpose is often defined as a business question or problem statement related to your organization’s goals. Examples include:
Once you’ve defined the problem, then you can start collecting data. Broadly speaking, there are three different categories of data, and the ones you use will depend on the nature of your problem. Most data analysis problems require a combination of the three.
First-party data is data that your own organization generates. Oftentimes, this is data about previous customer interactions that can be used to make accurate predictions about your customers’ behavior in the future.
You could also use second-party data—data that’s generated by external sources, but is about your company specifically. This can include what customers are saying on social media platforms or review websites.
Third-party data comes from groups like think tanks and government sources and is more concerned with the nature of your customer base, rather than a specific interaction that a customer has had with your company.
Not all the data you collect will be useful or accurate, and you’ll need to discard the data points that are irrelevant, duplicated, inconsistent, or outdated.
This is called data cleaning . When combining multiple sources of data, you’ll likely wind up with duplicates and outliers. And when you’re dealing with millions of data points, as is often the case with data analysis, you can’t comb through each piece of data on your own to find the duplicates or outliers. Data analysts estimate that the time spent cleaning data consumes about 70-90% of the data analysis process.
At this stage, you can also do an exploratory analysis, which is an initial and cursory data analysis. Exploratory data analysis will also assist with identifying other data points you may need.
Once you have all the relevant data, you can begin to process it. This entails organizing the data, sorting the data into relevant categories, and labeling them for easy organization. Now the data is prepped for analysis.
Data analysis can be done in numerous ways. One way is to use algorithms and mathematical models to manipulate data variables, which helps extract relevant information and valuable insights that tie into the problem defined in the first step.
Let’s look at the various data analysis techniques , which can be used in combination, depending on your problem.
As the name suggests, descriptive analysis describes or summarizes the data and its characteristics. It doesn’t go beyond explaining what has happened. You use this type of data analysis to deliver a narrative of what has occurred. Descriptive statistics and analysis present scattered data into digestible pointers. You can also do a part of this at the stage of exploratory data analysis.
With diagnostic analysis, you begin to focus on the “why,” and diagnose why something is occurring. At this stage, you are not looking for solutions or predictions. The goal is to understand the factors that are contributing to the problem. You use this technique when you want to go into issue identification mode.
Here’s where you start generating forecasts based on your data. Data analysts perform predictive analysis when they want to establish a situation in the future. This prediction helps stakeholders gauge business performance.
This kind of analysis brings together all of these data analysis techniques to offer recommendations. These form the basis of data-driven decisions.
With this technique, you derive conclusions based on the data you have collected and analyzed, such as, “lack of employee training is a cause of employee attrition” or “employee attrition affects customer satisfaction.”
Data visualization is a vital skill, especially when presenting your findings to non-technical stakeholders. Using data visualization tools you can share your insights with stakeholders and other target audiences. The statistical analysis needs to be easy to understand and easier to apply while making data-driven decisions. Interactive dashboards and visual representations of your findings will help.
Be mindful of these biases throughout the data analysis process:
Selection bias happens when you’re collecting data and cleaning it. There are several types of data analysis, including:
Confirmation bias is when you use data to support a pre-determined conclusion, rather than seeing what conclusions the data offers. You can avoid confirmation bias by covering all angles of the argument or problem. Give each perspective equal importance.
When organizations ignore anomalies in data to show a more streamlined picture, they engage in outlier bias. The most common example of outlier bias is revenue projections based on an average of factors, with well-performing variables hiding failures.
The biases we spoke about can be a result of shoddy data analysis or a consequence of other unavoidable pitfalls. These include:
You can avoid these pitfalls by having a clear strategy based on robust statistical analysis and data collection. Knowing the level of data readiness within your organization is also an excellent way to prevent unwanted surprises. Most of all, your analysis should always be tied to a core business question.

Here are the top tools for data analysis. They will help you collect, clean and mine data for efficient analysis:
An advanced understanding of Excel will help you clean and visualize your data. It allows you to use charts and conditional formatting to identify trends and patterns. You can perform the following activities with Excel :
As the name suggests, this tool is primarily used for data mining. But you can also use it for various statistical techniques, such as inferential statistics and descriptive statistics, to generate summaries and conclusions.
Tableau is a data visualization platform that allows you to share insights, collaborate over data analysis tasks, and share reports with stakeholders. Tableau has robust analytical features, such as limitless what-if analysis, and enables you to perform calculations with as many types of variables as you need.
Apache Spark helps with large-scale data engineering, regression analysis, and exploratory analysis, allowing you to analyze massive datasets.
We’ve got the answers to your most frequently asked questions:
Data analysis is used in many ways, but its most common applications include tracking customer behavior based on their purchase decisions, buying habits, and other consumer data points. Businesses then use this data to offer recommendations, improve customer experiences, inform marketing campaigns, and guide new product launches.
Garbage in, garbage out. Data cleaning is important for data analysis because data sources can be inconsistent, unreliable, and inaccurate. And no matter the size of your datasets, you’ll need to remove duplicate entries and outliers.
Data analysis is easy to learn if you have a plan. And that plan needn’t include a college degree .

Definition of research in data analysis: According to LeCompte and Schensul, research data analysis is a process used by researchers to reduce data to a story and interpret it to derive insights. The data analysis process helps reduce a large chunk of data into smaller fragments, which makes sense.
Definition: Data analysis refers to the process of inspecting, cleaning, transforming, and modeling data with the goal of discovering useful information, drawing conclusions, and supporting decision-making. It involves applying various statistical and computational techniques to interpret and derive insights from large datasets.
Data analysis methods refer to the techniques and procedures used to analyze, interpret, and draw conclusions from data. These methods are essential for transforming raw data into meaningful insights, facilitating decision-making processes, and driving strategies across various fields.
Like any science, a data analysis process involves a rigorous and sequential procedure based on a series of steps that cannot be ignored. Discover the essential steps of a data analysis process through examples and a comprehensive guide.
The Data Analysis Process: A Step-by-Step Guide. The process of data analysis is a systematic approach that involves several stages, each crucial to ensuring the accuracy and usefulness of the results. Here, we'll walk you through each step, from defining objectives to data storytelling.
In this post, we’ll explore the main steps in the data analysis process. This will cover how to define your goal, collect data, and carry out an analysis. Where applicable, we’ll also use examples and highlight a few tools to make the journey easier.
Through data analysis, a researcher can gain additional insight from data and draw conclusions to address the research question or hypothesis. Use of data analysis tools helps researchers understand and interpret data.
For most researchers, data analysis involves a continuous review of the data. Analysis for both quantitative and qualitative (numerical and non-numerical) data requires the researcher to repeatedly revisit the data while examining (Kumar, 2015): The relationship between data and abstract concepts.
