What’s on the Descriptive Statistics poster
A 6-row table: Measure · Is · Misleads when.
Measures of centre and of spread.
- Mean — The average — There are outliers
- Median — The middle value — The distribution is bimodal
- Mode — Most frequent — Data is continuous
- Range — Max − min — Only two points define it
- Std deviation — Typical distance from the mean — Data is skewed
- IQR — Middle 50% spread — Rarely — it is robust
Mean income and median income differ enormously, and the gap is itself the finding. Quote both.
Questions about the Descriptive Statistics poster
- What’s on the Descriptive Statistics (Data) poster?
- A 6-row table: Measure · Is · Misleads when. Measures of centre and of spread.

Mean income and median income differ enormously, and the gap is itself the finding. Quote both.
- Who is the Descriptive Statistics (Data) poster for?
- Descriptive Statistics (Data) belongs to the Computing section rather than to a school year, because computing is not something one grade owns. Anyone learning data can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Descriptive Statistics (Data) poster?
- Always look at the distribution before quoting an average. One number hides the shape. A wall chart earns its place by being glanceable from where the work is happening, so Descriptive Statistics (Data) belongs on the wall where that computing work actually happens, within glancing distance, rather than filed away.
- What other posters go with Descriptive Statistics (Data)?
- ACID, The CAP Theorem and Choosing a Chart sit alongside Descriptive Statistics (Data) in the Computing section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.ACIDThe CAP TheoremChoosing a Chart
- Is the Descriptive Statistics (Data) poster free to download and print?
- Yes. Descriptive Statistics (Data) downloads as a free PDF with no account, no email and no watermark, like everything else in the Computing section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Descriptive Statistics (Data) poster print at?
- Descriptive Statistics (Data) is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Descriptive Statistics (Data) loses nothing.Printing guide
