What’s on the Continuous Distributions poster
A 6-row table: Distribution · Mean · Variance.
Standard densities and their first two moments.
- Uniform(a, b) — (a + b)/2 — (b − a)²/12
- Normal(μ, σ²) — μ — σ²
- Exponential(λ) — 1/λ — 1/λ²
- Gamma(k, λ) — k/λ — k/λ²
- Chi-square, k d.f. — k — 2k
- Student t, k > 2 — 0 — k/(k − 2)
The exponential is memoryless: how long you have waited says nothing about how much longer. No other continuous law does that.
Questions about the Continuous Distributions poster
- What’s on the Continuous Distributions poster?
- A 6-row table: Distribution · Mean · Variance. Standard densities and their first two moments. Uniform(a, b) — (a + b)/2 — (b − a)²/12; Normal(μ, σ²) — μ — σ²; Exponential(λ) — 1/λ — 1/λ²; Gamma(k, λ) — k/λ — k/λ²; Chi-square, k d.f. — k — 2k; Student t, k > 2 — 0 — k/(k − 2). The exponential is memoryless: how long you have waited says nothing about how much longer. No other continuous law does that.
- Who is the Continuous Distributions poster for?
- Continuous Distributions belongs to the Mathematics section rather than to a school year, because math is not something one grade owns. Anyone learning probability & statistics can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Continuous Distributions poster?
- For a quick sanity check on a simulation or an estimate. A wall chart earns its place by being glanceable from where the work is happening, so Continuous Distributions belongs on the wall where that math work actually happens, within glancing distance, rather than filed away.
- What other posters go with Continuous Distributions?
- Bayes' Theorem, Central Limit Theorem and Conditional Probability sit alongside Continuous Distributions in the Mathematics section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Bayes' TheoremCentral Limit TheoremConditional Probability
- Is the Continuous Distributions poster free to download and print?
- Yes. Continuous Distributions downloads as a free PDF with no account, no email and no watermark, like everything else in the Mathematics 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 Continuous Distributions poster print at?
- Continuous Distributions 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 Continuous Distributions loses nothing.Printing guide
