Karl Pearson, 1891, as a graphical frequency distribution
What does it encode?
count of observations inside each bin
Is it OK in ads?
Yes if one claim is visible at a glance in Meta, Google and retail print; otherwise link to a full figure.
Will a teacher accept it?

Histogram encodes values as count of observations inside each bin. Karl Pearson, 1891, as a graphical frequency distribution.
In reports, ads and assignments it fits one continuous measurement and its shape. Skip it when bins differ in width, or you are comparing named categories.

Work
- Work 1 — PowerPoint weekly: Histogram for one continuous measurement and its shape.
- Work 2 — One Histogram on a quarterly bridge or KPI tile — not four.
- Work 3 — Build in Excel or Google Sheets, export SVG/PDF rather than a screenshot.
Ads
- Ads 1 — Meta, Google and retail print: one number, one shape, one arrow.
- Ads 2 — Keep callouts inside safe zones. No type in cropped corners.
- Ads 3 — If Histogram will not fit a banner, keep the number and show the chart on the landing page.
School
- School 1 — lab reports and poster boards: does Histogram answer the rubric?
- School 2 — Axis names, units, a source line. Markers read them.
- School 3 — Start with a mind map if you must; submit a figure that reads like Histogram.
Steps
- Steps 1 — Write the claim in one sentence.
- Steps 2 — Check that Histogram fits the claim. If not, switch.bins differ in width, or you are comparing named categories
- Steps 3 — Draw it flat in Excel or Google Sheets or PowerPoint.
- Steps 4 — Direct labels, faint grid, claim-title.
- Steps 5 — Check greyscale and a color-blind simulator.
- Steps 6 — Add source, period, units; export SVG/PDF.
Histogram: honour count of observations inside each bin, and switch when bins differ in width, or you are comparing named categories.
