Universities and academic institutions can perform the analysis to measure student performance and gather insights on how certain behaviors can further improve education.
Techniques for data analysis
It is essential to analyze raw data to understand it. We must resort to various data analysis techniques that depend on the type of information collected, so it is crucial to define the method before implementing it.
- Qualitative data: Researchers collect qualitative data from the underlying emotions, body language, and expressions. Its foundation is the data interpretation of verbal responses. The most common ways of obtaining this information are through open-ended interviews, focus groups, and observation groups, where researchers generally analyze patterns in observations throughout the data collection phase.
- Quantitative data: Quantitative data presents itself in numerical form. It focuses on tangible results.
Data analysis focuses on reaching a conclusion based solely on the researcher’s current knowledge. How you collect your data should relate to how you plan to analyze and use it. You also need to collect accurate and trustworthy information.
Many data collection techniques exist, but experts’ most commonly used method is online surveys. It offers significant benefits, such as reducing time and money compared to traditional data collection methods.
Data analysis and data analytics are two interconnected but distinct processes in data science. Data analysis involves examining raw data using various techniques to uncover patterns, correlations, and insights. It’s about understanding historical data to make informed conclusions. On the other hand, data analytics goes a step further by utilizing those insights to predict future trends, prescribe actions, and guide decision-making.

Step 1: Define your questions
Start by selecting the right questions. Questions should be measurable, clear, and concise. Design your questions to qualify or disqualify possible solutions to your specific problem.
Step 2: Establish measurement priorities
This step divides into two sub-steps:
- Decide what to measure: Analyze what kind of data you need.
- Decide how to measure it: Thinking about how to measure your data is just as important, especially before the data collection phase, because your measurement process supports or discredits your thematic analysis later on.
Step 3: Collect data
With the question clearly defined and your measurement priorities established, now it’s time to collect your data. As you manage and organize your data, remember to keep these essential points in mind:
- Before collecting new data, determine what information you could gather from existing databases or sources.
- Determine a storage and file naming system to help all team members collaborate in advance. This process saves time and prevents team members from collecting the same information twice.
- If you need to collect data through surveys, observation, or interviews, develop a questionnaire in advance to ensure consistency and save time.
- Keep the collected data organized with a log of collection dates, and add any source notes as you go along.
Step 4: Analyze the data
Once you’ve collected the correct data to answer your Step 1 question, it’s time to conduct a deeper statistical analysis. Find relationships, identify trends, and sort and filter your data according to variables. You will find the exact data you need as you analyze the data.
Step 5: Interpret the results
After analyzing the data and possibly conducting further research, it is finally time to interpret the results. Ask yourself these key questions:
- Does the data answer your original question? How?
- Does the data help you defend any objections? How?
- Are there any limitations to the conclusions, any angles you haven’t considered?
If the interpretation of data holds up under these questions and considerations, you have reached a productive conclusion. The only remaining step is to use the process results to decide how you will act.
