Core Skills Analysis
Math
Lorien gathered a set of numbers from her data science project and calculated the mean, median, and mode to summarize the central tendencies. She then used percentages to compare categories within the data set, reinforcing her understanding of fraction-to-percent conversions. By creating bar graphs and pie charts, Lorien practiced scaling and proportion concepts while visualizing numerical relationships. Throughout the activity, she applied basic algebraic formulas to predict trends, demonstrating how math underpins data interpretation.
Science
Lorien followed the scientific method by forming a hypothesis about the pattern she expected in the data and then designing a procedure to collect it. She recorded observations methodically, noting variables that could affect outcomes, which sharpened her skills in controlled experimentation. After analyzing the results, Lorien drew evidence‑based conclusions and reflected on potential sources of error, linking data analysis to empirical reasoning. This process helped her see how scientific inquiry relies on accurate data collection and interpretation.
Computer Science
Lorien used a simple spreadsheet program to organize raw data, sort it, and apply built‑in functions for calculations, gaining hands‑on experience with digital tools. She wrote basic formulas to automate repetitive calculations, reinforcing logical sequencing and debugging when results didn’t match expectations. By creating visual dashboards, Lorien learned how coding concepts like loops and conditionals can streamline data visualization. The activity introduced her to computational thinking, showing how algorithms turn raw numbers into meaningful insights.
Tips
To deepen Lorien's data science journey, have her design a new survey on a topic she cares about and collect classmates' responses. Next, guide her to use a free coding platform (such as Scratch or Python with Turtle) to build an interactive chart that updates in real time. Finally, encourage her to write a short research report that includes an introduction, methods, results, and a reflection on what the data reveals about her original hypothesis.
