This applet is for visualising the Binomial Distribution, with control over n and p.
It also shows the Normal Approximation curve (and how this approximation breaks down for large or small p)
You can show critical regions at either end by turning the bars red instead of green – this feature is purely for visualising critical regions when performing hypothesis tests with the binomial distribution (you still have to calculate the critical regions yourself). I hope to automate this too in a future version of the applet.
When taking square roots of both sides of an equation, one should be careful not to turf out the negative result without first considering whether it has a true meaning. When using Pythagoras’ Theorem, the last step is to take square roots. So, can we have a hypotenuse with length -5?
The original motivation behind this was an attempt to save my Statistics students a few precious seconds in their upcoming S1 module paper.
The mean or expectation of a Binomial Distribution is always very close to mode or the value of X that has greatest probability. I want to know if you can use the mean to reliably predict the mode.
Good morning.
I want to talk to you today about our monetary system. Most, perhaps all, of us here at Forest School have benefited from the monetary system. Money affords us food, entertainment, transport, holidays; a place to live; stability. Money creates incentives; it gives us jobs, careers and aspirations; and taxes allow huge investments like high-speed rail links and the Olympic park.
But does everyone benefit from our monetary system?
We’re born into a society of which money seems to be the driving force. Where does money come from? Who gives us it to spend?
Please forgive my appalling lack of posts in recent months. I’ve been working on a project with the above name, which seeks to place cameras in objects that can rotate on any axis, a football for example! Exciting stuff, but I can’t share the maths with you on here.
In 1975, a new word came into use, when a maverick mathematician made an important discovery. So what are fractals? And why are they important?
Mandelbrot developed fractals as a mathematical way of understanding the infinite complexity of nature.
The concept has been used to measure coastlines, clouds and other natural phenomena and had far-reaching effects in physics, biology and astronomy.
