Elementary Statistics tools and techniques are important to many branches of science. Below and on subsequent pages we will connect you to a wide range of executable examples of statistics equations and you will be able to play with them and see how they work.
vCalc equations can actually calculate. This isn't just written equations. Watch for links to vCalc equations that actually allow you to perform statistical analysis on your own examples.
NOTE: many vCalc equations are embedded throughout vCalc descriptive pages like this page. Even though they may not stand out in the text, if you hover over the name of an equation it will likely be linked to an actual, pop-up executable equation. For example: Arithmetic Mode
This branch of mathematics, statistics, is often regarded as a necessary evil by psychology and education students aspiring to postgraduate studies, but inevitably statistics becomes ingrained in their thinking about their core studies. The physics student quickly finds that laboratory experiments immersed in statistics can illuminate the physical phenomena they are studying in ways other viewpoints cannot. Business student use statistics to reduce risk and focus resources and thus come to rely on statistical analysis to be better at their business.
We use statistics in our everyday lives, just like many forms of mathematics. We learn at an early age to gauge what is average, what is less than and what is the maximum. We look at the students in our kindergarten classroom and we recognize that we are shorter or taller than most of the children. We are learning the fundamentals of statistics.
Wouldn't it have been nice to mark the fact that you were learning elementary statistics when you were in 1st grade?
The ease with which you can scroll through the statistics concepts presented here and quickly understand the mechanics of applying statistical analysis to the concrete data of real research is a testament to how direct is the tie of statistics to the real world. When you think about the logic behind these simple statistics methods, so much of the mathematics will be quite intuitive.
This collection derives and explains many of the most common statistical applications. There are very many useful textbooks on statistics available today and many that explain the nature of the mathematics in much more detail than we shall do here. We shall strive to get right to the heart of the statistical equations and present them with informative examples and then leave you to experiment with the vCalc equations to see even better how these statistical analysis techniques work.
