Description:
The SOCR philosophy has four parts: "1. Tools must be freely available on the Web (SOCR Motto: It’s online, therefore it exists!) 2. Newly developed materials must be useful, extensible, factually correct, validated and deployed on the web. 3. Tools must be well designed, extensible, platform-independent and open-source; 4. Materials must explicitly utilize some SOCR interactive resources (e.g., activities with applet demos) and provide the means of cross reference by various SOCR tools (e.g., applet calculations citing formulas in instructional materials)." Each section of the site consists of an instructional applet with many customizable settings, and three sections are worth noting. First, Interactive Distributions provides graphical illustrations of over 30 different statistical data distributions. An especially useful feature of this applet is the Info button -- when pressed, it takes the user to a detailed description of the selected distribution. The second section allows the user to perform a variety of statistical analyses on pre-defined or manually input data. These include analysis of variance (ANOVA), regression and correlation, and more. The third section is a modeler for a user-defined function. The user can draw a curve and the applet will fit a trend line to the curve. A serious shortcoming of this site is the lack of documentation provided with certain applets; while this is not an issue with the aforementioned sections, it makes the two remaining sections nearly unusable. |
