- WISE
(Web Interface for Statistics Education) home page. This is probably the most in depth and complex web site that we suggest. It could reasonably be included in earlier chapters, and will be mentioned again in the next. The WISE site’s objectives include providing online statistics tutorials, answers to commonly asked questions about statistics, and links to other useful statistical resources. Their home page is very well organized and intuitive, but it is easy to get lost once inside—although this is not necessarily a bad thing.
- Probability of z-scores
As a convenient example starting point on the WISE web site, this link on the probability of z-scores is located in the subdirectory "Tutorials" at "Sampling Distributions of the Mean". There is a continuously growing wealth of material available at this site, so you might find it useful to explore it as you encounter new statistical concepts or problems in this and other research or statistics courses.
- Guidelines for the Design of Forms
The page created by the MedStar Research Institute provides a few more guidelines for creating a data collection form. A point to understand after looking at both what the text and this site have to say on data collection forms is that each research question is unique, and the data collection form that you will need to construct will reflect this. None-the-less, certain information is almost always collected, e.g., age, gender, etc.
- Descriptive Statistics
This introduction to descriptive statistics covers the three measures of central tendency as well as range, variance and standard deviation. Not only does it include exercises and examples, it is entertaining as well.
- Seeing Statistics
Gary H. McClelland at the University of Colorado at Boulder has created an electronic statistic book called "Seeing Statistics." At this site, he has provided links to four applets that visually demonstrate normal probabilities and z-scores.
