Your First Dataset Project, End to End

A complete walkthrough from question to shareable dataset. The first project is the hardest; this lesson gets you to the other side.

The Project Arc

Every dataset project moves through the same phases: ask a question, find or collect data, explore and clean, analyze, communicate, and share. Miss any phase and the project feels broken. Let's walk through a concrete example end to end.

The example: Spotify top songs

Imagine you want to answer: do songs with higher danceability get more streams? The Kaggle dataset Top Spotify Songs 2023 has exactly what you need. We will take it from download to a polished notebook.

Phase 1: scope your question

Question: does danceability correlate with streams?
Success criterion: a single statistic (correlation coefficient) plus a plot
Time budget: 3 hours total
Out of scope: causation (which requires experiments)

Phase 2: get the data

# Download from Kaggle (requires kaggle CLI setup)
# kaggle datasets download -d nelgiriyewithana/top-spotify-songs-2023

import pandas as pd

df = pd.read_csv('spotify-2023.csv', encoding='latin-1')
print(df.shape)
print(df.columns.tolist())
print(df.head())Load and inspect the Kaggle dataset

Phase 3: explore and clean

# Check types and missing values
print(df.dtypes)
print(df.isna().sum())

# Streams came in as string with commas, fix it
df['streams'] = pd.to_numeric(df['streams'], errors='coerce')
df = df.dropna(subset=['streams', 'danceability_%'])

# Quick summary
print(df[['streams', 'danceability_%']].describe())Type-fix the streams column

Phase 4: analyze

import matplotlib.pyplot as plt
from scipy.stats import pearsonr, spearmanr

# Pearson assumes linear; Spearman is rank-based
pearson_r, p = pearsonr(df['danceability_%'], df['streams'])
spearman_r, sp = spearmanr(df['danceability_%'], df['streams'])

print(f'Pearson r: {pearson_r:.3f} (p={p:.3f})')
print(f'Spearman rho: {spearman_r:.3f} (p={sp:.3f})')

# Log-scale the streams for a readable plot
plt.scatter(df['danceability_%'], df['streams'], alpha=0.3)
plt.yscale('log')
plt.xlabel('Danceability (%)')
plt.ylabel('Streams (log scale)')
plt.title('Danceability vs. Streams')
plt.show()Compute correlation and plot

Phase 5: communicate

Phase 6: share

Push notebook to GitHub or Kaggle
Write a one-paragraph README with the question, method, finding
Include a data card noting the dataset source and license
Tag your notebook with readable headings so others can follow

The big idea: a dataset project is a small disciplined arc. Following the six phases turns chaos into a portfolio piece. Do one, then another, then ten. That is how data intuition develops.
