This technique allows for the visual organization of collected information and identification of revelations. It is important to sift through the information obtained in the empathy phase.
The technique saturate and group is also known as Clustering, data segmentation, clustering technique, group classification technique.
What is this technique/tool about
The clustering technique allows to organise large datasets, identify specific groups or segments, and analyse similar trends or behaviours, providing a better understanding and organisation of information.
There are different clustering algorithms, such as k-means, DBSCAN, hierarchical, among others, each with its own characteristics and approaches. The choice of algorithm depends on the nature of the data and the objectives of the analysis.
For which purposes is it used (why in your high school teaching)
The clustering technique is used in different contexts and disciplines due to its various applications and benefits. The following are some of the reasons why clustering is used:
In the context of secondary education, the use of clustering can help to identify different profiles of students with similar characteristics, allowing educators to adapt their pedagogical approach and provide more personalised interventions. It can also be useful for segmenting groups of students with specific needs, which facilitates the planning of appropriate support programmes and educational resources for each group.
Limitations
Although the clustering technique is a useful tool, it also has some limitations that are important to bear in mind:
Dependence on data quality: The quality of the input data can have a significant impact on the clustering results. If the data are incomplete, have errors or contain outliers, this can negatively affect the accuracy and consistency of the clusters obtained. It is important to perform a data cleaning and pre-processing process to reduce these effects.
Subjective interpretation of results: The interpretation of clustering results can be subjective and depends largely on the knowledge and experience of the analyst.
Clustering consists of grouping items into groups with similar characteristics and is used to determine weather patterns, group items by topic or to segment customers. In short, its objective is to form closed and homogeneous groups from a set of elements that have different characteristics or properties but share certain similarities.

Some examples and testimonies that could illustrate the application of the clustering technique:
Example 1:
In a research project in a secondary school, students collected data on the music preferences of their classmates, such as favourite music genre, favourite artists, and frequency of listening. Using the technique of clustering, they grouped students into different segments based on their musical preferences. This allowed them to identify groups of students with similar tastes and to analyse common characteristics within each group.
Testimonial 1:
'Applying the clustering technique in our project was a fascinating experience. We were able to see how our classmates were grouped into different categories according to their musical tastes. This helped us to better understand the different social groups within our school and gave us ideas for organising musical events and activities more in line with our classmates' interests.' - Secondary school student.
Example 2:
In a social science project, students collected data on the study habits of their classmates, including variables such as time spent studying, techniques used and academic performance. Using clustering, they identified different student profiles based on their study habits and assessed the relationship between these profiles and academic success.
Testimony 2:
'The clustering project allowed us to explore how different study approaches can influence academic performance. We were able to identify groups of students with similar study strategies and observe the differences in their results. This helped us to reflect on our own study techniques and learn from the successful approaches of our peers.' - Secondary school student.
To develop it, we will need a wall to place post-its on.
In the context of secondary education, there are several tools that can be used to implement and apply clustering techniques.
It is important to consider the level of knowledge and technical skills of the students and the resources available in the educational institution when selecting appropriate tools. In addition, it is advisable to provide guidance and technical support to students during the use of these tools to ensure a correct implementation and understanding of clustering concepts in the context of secondary education.
