Mathematics: Mode, median and mean averages
By: Erik Setser
Understanding the science of statistics begins with the ability to interpret sets or series of data. In the case of purely numerical data, this in turn begins with an understanding of the three Ms of statistics: mean, median and mode. Mean is another word for...

A quadratic equation is a mathematical sentence which describes a graph of a parabola. The roots of the equation are the two points where this parabola crosses the y-axis, upon which y = 0. However, complex roots may be found in certain conditions. First, let's...
Mathematics: Mode, median and mean averages
By: Matthew Adams
The mode, median and mean averages are three types of average that can be used for various numerical ranges. To look at each separately: Mode The mode is actually the most straightforward of these averages. It is the most common value, from within a range...
Mathematics statistics: Confidence intervals and confidence limits
By: Michelle Tuesday
Statistics is the study of samples sets of data. Statistical study of data samples is used to make inferences about the entire population that the sample represents. For example, suppose you have a large order of French fries. After eating five fries and finding them...
Set Theory explained
By: Claus Martin
Basics of set theory, part 1: lists, sets, universal set, zero set and elements of a setSet theory is the base of modern mathematics. It has been developed by Cantor in the 19th century. Later Bertrand Russell and Whitehead, developed axioms for the set theory...
Mathematics: Mode, median and mean averages
By: Robby Powell
In collecting data, people always want to know how to best describe the data. The first technique often used is to calculate a mean, median, and mode, three statistics that do provide description of the central tendency of the data. These statistics then provide...
Mathematics: Bar, line and Pie graphs
By: Helena Whyte
A graph is a visual display of numeric values. A graph is a picture. Graphs make numbers and number comparisons more understandable. Graphs summarize data, show trends, and display patterns. Graphs make it quick and easy to interpret a large amount of data. The most...
Mathematics: Bar, line and Pie graphs
By: Mike Mueller - 512349
The purpose of a graph is to visually depict a set of data in a manner that all of the data can be viewed simultaneously and quickly processed by the interpreter. A graph is typically presented on a two dimensional medium and therefore the simplest...
What is Xeno's Paradox?
By: Helena Whyte
What Is Zeno's Paradox? Webster's Dictionary defines a paradox as a statement that seems to be contradictory or opposed to common sense and yet is true. The Greek philosopher Zeno proposed a series of conundrums, posers, or paradoxes to demonstrate the impossibility of motion in...
Finding the area of a circle
By: Helena Whyte
Finding the Area of a Circle The easiest way to find the area of a circle is to draw a circle on graph paper. Then count the number of squares or grids inside the circle. This method requires drawing the circle precisely on the lines...
