Find two sets where the median of one is the mean of the other and vice versa in C#

Posted on July 23, 2018 by RodStephens

For an upcoming book, I wanted to find sets where the mean (average) of one is the median (middle value) of the other and vice versa. I wanted to avoid trivial examples such as {1, 1, 1} and where the … Continue reading →

Make a dice-rolling simulation in C#

Posted on September 21, 2017 by Rod Stephens

This example performs a simulation of rolling two six-sided dice. It’s related to my book Interview Puzzles Dissected, which includes several examples that involve rolling dice. When you enter a number of trials and click Roll, the program uses the … Continue reading →

Draw a scaled normal distribution in C#

Posted on September 8, 2015 by RodStephens

The example Draw a normal distribution curve in C# shows how to draw a normal distribution. Unfortunately for some means and standard deviations, the result may not be very useful. For example, Figure 1 shows a normal distribution where the … Continue reading →

Draw a normal distribution curve in C#

Posted on September 4, 2015 by RodStephens

A normal distribution is a probability distribution that occurs arise when you analyze seemingly “random” occurrences. You can define a normal distribution in terms of its mean and standard deviation. Mean (μ) This is the basically the average of the … Continue reading →
