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

Plot data with standard deviation ranges in C#
The examples Draw a normal distribution curve in C# and Draw a scaled normal distribution in C# show one approach for visualizing how data is distributed. This example shows a method that lets you visualize where a particular data value … Continue reading
Draw a scaled normal distribution in C#
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#
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
