Correlation insight

Positive correlation

Verdict: There is a positive correlation between girls building a web application and how confident they felt in their coding skills. Builders reported fewer low‑confidence responses (25% vs 71%) and a higher average confidence score (2.0 vs 1.43 on a 1–3 scale). The correlation is moderate, not absolute, due to small sample size and some mixed cases.

✔

Positive insights

  • Girls who built a web app showed a higher share of Somewhat/High confidence (75%) compared to non‑builders (29%).
  • Strong individual examples of confidence appear even without building a web app, suggesting multiple pathways to confidence.
  • Among builders, most reported at least Somewhat confidence, indicating project experience helps comfort with coding tasks.
⚠

Negative insights

  • Many non‑builders expressed low confidence tied to inexperience, confusion, or anxiety about where to start.
  • At least one builder reported low confidence due to debugging challenges, showing that building alone does not guarantee confidence.
  • High missing or unspecified responses reduce certainty and may bias the observed correlation.

Illustrative voices

Builder (High): I feel very confident about my coding skills because I have built a few web apps from scratch.
Non‑builder (High): I feel confident because I can solve most of the coding challenges we get in our after‑school program.
Builder (Low): I am not very confident because I often need help debugging and do not always understand what went wrong.
Non‑builder (Low): I am not confident at all because I have never coded before and it seems really complicated.
