Do you need to feel more confident about using statistics?
Dismayed by overly complicated "introduction" courses
that focus on theory and not application? Do the "basic"
books assume you know where to look for your answer ?
Understanding and successfully using confidence intervals
requires the mastery of the following components:
- The Margin of
Error
- Sample Size
- Confidence
Level
- Population Variability
- Standard Deviation
- Degrees of Freedom
- Standard Error
- Binomial Populations
- Calculating and Interpreting Confidence Intervals
You can start the lesson
from the beginning or go right to a specific component.

How the Lessons Work
During the lessons, you'll see "sliders"
like the one on the right --->
Use these sliders to indicate how clear a section of the material
is to you. The information will be used to make the lessons easier
to understand. At the end of one or two concepts, you'll be asked
a couple of question to see if things are making sense. You can
always retake a module, a quiz or skip ahead if the content is too
easy.
You'll also see this U
symbol within the text. Clicking on this shows areas where users
had problems understanding the material and contains more clarification
that helped them better understand the content.
