By: Josh Komon
Mean, median, mode, first quartile, third quartile; all these are parts of the measures of central tendency. Some of these are easy to find no matter how many data pieces there are, others are much more difficult, even with only a few. Thankfully, we have...
 Lagrangian mechanics: Brachistochrone problem By: Wes Kelly Though brachistochrone means “shortest time” in Greek, the set of problems originated with the Swiss mathematicians, John (1677-1748) and James Bernoulli.(1654-1705). It was John Bernoulli who first posed the problem of finding the shortest time of descent for a bead sliding on a...
Mathematics: Statistics and probability
By: Josh Komon
For many, statistics and probability are the most fun aspects of mathematics. These two related sub categories involve much more of the doing that can make math interesting and fun. Statistics are used in every day life. Probability is appreciated by those who enjoy games...

Statistical, or pseudo-statistical are everywhere around us. Many of the media articles quoting statistical or survey data are accompanied by graphs, and statistical graphs are also essential part of scientific and business reports. But are all statistical graphs useful? How to rate a graph one...
Basic statistical concepts: Data collection by experimentation method
By: Lime Red Tetrahedron
We live in a world in which we are constantly surrounded by data - counts, figures, lengths, colors, etcetera. With such an enormous amount of data penetrating our lives, how do we make sense of it? This is where the mathematical methods of statistics come...
What is an artificial neural network?
By: Michael Mackie
Artificial Neural Networks Neural Networks are one of the three main knowledge based systems. The others being AI (Artificial Intelligence), Fuzzy Systems, as well as hybrid systems. Neural Networks try to mimic humanlike rationalization. Inspired to reproduce the reasoning and processing elements otherwise known as...
Graphs and charts are a way that data and statistics can be presented. As such, there are a variety of graphs and charts such as bar graph, correlation graph, line graph and pie charts. A few of these graphs can be considered here. Firstly, it...
How statistics can be manipulated
By: Rick Gene
Television news programs often run surveys where they invite their viewing audience to participate in some silly poll by texting their opinions (at 99 cents per message) to the number they provide. Then the news programs show the results and you can see how stupid...
Stats and probability in Mathematics is often used for recording and forecasting. The stats themselves are more recorded for reference, while the probability or likelihood is more for forecasting. So, let us first consider statistics. Statistics really refers to recorded stats. Stats are widely used...
How to use a graphing calculator to solve a system of equations
By: Josh Komon
Solving a system of equations can be difficult for those who are just starting out. However, with a graphing calculator, solving these becomes much easier. In order to do this, one must first understand that an equation in two variable can be represented graphically, often...
