Scatter Plot

Points plotted on X-Y axes showing the relationship between two numeric variables.

A free, animated scatter plot you can read here or embed on any website, from Scrollchart.

Scatter Plot

A scatter plot places one observation per dot. The horizontal position encodes one variable; the vertical position encodes another. The resulting cloud reveals whether the two variables are related, and if so, whether that relationship is positive, negative, linear, or curved.\n\nScatter plots also expose structure that summary statistics hide. Two datasets can share identical means, standard deviations, and correlations while looking completely different when plotted. This is the lesson of Anscombe's Quartet (1973): always plot the data before trusting the numbers.

Good for

  • Articles in the statistics category
  • Editorial pages where a quick visual replaces a wall of text
  • Content-marketing posts that need a clean, branded illustration

Source & accuracy

This scatter plot is an editorial illustration built to represent the concept accurately. Where it shows figures, they are typical or representative values chosen to make the relationship clear, not a single underlying dataset. The diagram and its explainer are reviewed and maintained centrally, and updated over time as understanding improves.

Visualizing association between two measurements

A scatter plot displays individual data points on a 2D grid where the horizontal axis represents one variable and the vertical axis represents another. Each dot's position reveals the simultaneous value of both measurements for a single observation. This simple format makes patterns in association immediately visible.

Reading directions and strength of relationships

When dots trend upward left-to-right, the variables have a positive correlation: as one increases, the other tends to increase. A downward trend shows negative correlation. Tight clustering around an imaginary line indicates a strong relationship; scattered points suggest a weak one. Scattered data doesn't mean one variable is useless for predicting the other, merely that other factors also influence the outcome.

Spotting outliers and subgroups

Outliers appear as isolated dots distant from the main cloud, signaling unusual observations or potential data errors. A scatter plot also reveals subgroups: you might see two distinct clusters indicating your sample contains two populations with different characteristics. Such visual insights prompt further investigation that summary statistics alone would miss.
