Qualitative data

Here you will learn about qualitative data, including what it is and how to use it in the statistical process.

Students first learn to work with qualitative data in the statistical process in 6 th grade.

What is qualitative data?

Qualitative data is information that describes characteristics or qualities about something. It is typically non-numerical, but can involve numbers that do not represent a quantity.

There is one type of qualitative data: categorical.

  • Categorical data – data that can be grouped into categories instead of being measured numerically.

Some examples of qualitative data are…

\; Favorite color

\; Brands

\; Hair color

\; Eye color

\; Zip code

The statistical process gathers, analyzes and draws conclusions based on qualitative data.

You can begin the statistical process by writing a statistical research question. A statistical question always allows for variability.

For example,

What is my favorite color?What is the most popular color among
6th graders at my school?
This is NOT a statistical question,
because there is one answer.
This is a statistical question that allows
for variability.

Many researchers also create hypotheses to go with the question, but this is not required.

The next part of the process is planning and completing data collection. Some qualitative data collection methods are focus groups, surveys, experiments, case studies, interviews, or questionnaires. The method chosen depends on many things, some of which include…

  • How much time do you have for data collection?
  • What resources (including money) can you use to collect data?
  • Will the data be collected from the entire population or a sample?

For example,

What is the most popular color among 6 th graders at my school?

One way this data can be collected is by emailing a survey to every student in the school – which would be a quick and free way to collect data on the entire population.

Once you have collected all observations (the final number of respondents or data points), it is time to begin the statistical analysis.

The analysis process begins with deciding which graphs or methods you will use to analyze the data. Analyzing qualitative data includes using dot plots, bar graphs, pie charts and more.

Finally, qualitative data analysis is used to draw conclusions and answer the original question asked based on the collected data.

The answer to a statistical question should always take into account all parts of the process and anticipate ways in which the data may be a flawed representation.

Common Core State Standards

How does this apply to 6 th grade math?

  • Grade 6 – Statistics and Probability (6.SP.B.5a and 6.SP.B.5b)
    Recognize a statistical question as one that anticipates variability in the data related to the question and accounts for it in the answers. For example, “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question because one anticipates variability in students’ ages.

  • Grade 6 – Statistics and Probability (6.SP.B.5a and 6.SP.B.5b)
    Summarize numerical data sets in relation to their context, such as by:
    • Reporting the number of observations.
    • Describing the nature of the attribute under investigation, including how it was measured and its units of measurement.

How to write a qualitative statistical question

In order to write a qualitative statistical question:

  1. Think of a question that would be answered with a category.
  2. Write the question to allow for variability.

Qualitative data examples

Example 1: writing a qualitative statistical question

Create a qualitative statistical question.

  1. Think of a question that would be answered with a category.

What is your favorite genre of music?

This could be answered with rock, pop, hip hop, electronic, country, etc…

2Write the question to allow for variability.

Since each person has one favorite genre, asking just one person will not provide a variety. Instead, you need to choose a group of people to be the population for the question.

For example,

Which music genre is the favorite of my family members?

Now the question will have a variety of answers, because the data population is every member in your family.

Example 2: writing a qualitative statistical question

How to use the statistical process with qualitative data

In order to use the statistical process with qualitative data:

  1. Ask a question that allows for variability and categorical data.
  2. Decide on data collection methods and perform data collection.
  3. Analyze the categorical data.
  4. Draw conclusions to connect the data collected to the original question.

Teaching tips for qualitative data

  • Incorporate project based learning activities where students have the opportunity to collect their own data by doing experiments, creating surveys, or conducting interviews. This will help students develop a deeper understanding of the statistical process.

  • In the classroom, use real world examples of qualitative data. These can be things like bar graphs or pie charts from newspaper articles or data collected in the school setting (such as the types of shoes students wear on a certain day or comparing the favorite sport of students in different grade levels).

  • Consider doing a long, in-depth class project throughout the entire unit. As a class, students can decide on a topic, and then within smaller groups, students can explore different statistical research questions (both quantitative and qualitative). Then students can share their group analysis with the class and come to a conclusion together – considering all the research that was completed.

Easy mistakes to make

  • Thinking that categorical data never has numbers
    While categorical data should not involve quantities, it can involve categories with numbers. For example, the categories 1 st, 2 nd, 3 rd, 4 th and so on can be used. As well as representing the months of the year by their order number 1 – January, 2 – February, etc.

  • Not choosing reliable data sources
    If you are using data that you did not collect yourself, always make sure it comes from a reliable source. This can include (but is not limited to) official government websites, official team websites (for sports data), or directly from a book or cited study.

Once a question is created, the data needs to be collected. The collected data can then be analyzed.

 

Lastly, use the analysis to draw a conclusion based on the question and the data collected.

Qualitative data FAQs

Are open-ended questions used for quantitative research or qualitative research?

Both – research data can be collected with open-ended questions in both non-numerical data and numerical values form.

A qualitative approach to this question style may involve a short response (such as yes or no) or a longer response (such as a story or a detailed explanation).

A quantitative approach will always involve giving some sort of quantity as an answer.

Is there a difference between qualitative vs. quantitative research methods?

Qualitative research methods and quantitative research methods have very similar methodologies. They differ most during the analysis portion of the process.

How is qualitative data used in a real world job?

There are endless uses for qualitative data in real world jobs. One includes a market researcher, whose job it is to complete the statistical process for companies and businesses.

It is their job to ask statistical questions, perform data collection and analysis on the data set. It is important to note that both types of data (quantitative and qualitative) are integral parts of the data analysis process in the real world.

Can in-depth interviews be used to collect qualitative data?

Yes, particularly for qualitative research studies involving people and complex topics (such as psychology).

The research design typically allows for a small sample size of people (since this type of research is time consuming). The interview can range from a set list of questions to very unstructured (letting the participant guide the discussion).

In-depth interviews can be administered by a researcher, a non-bias moderator, or by the use of technology. Then, the audio recordings from the interviews are then turned into interview transcripts, which can be used for analysis and conclusion purposes.
