Student Review (Not based on classroom experience) Reviewer: Deatra, Dec 6 2005 07:28:12:477PM |

Review based on: I discovered it by searching on the Math Tools DL, but I liked it because it was a quick and easy way to allow students to plot points, see a regression line, and view standard deviation. I liked the fact that it was simple to use and that it worked fast. |

Appropriate for: practice of skills and understandings, applications of a concept or technique |

Other Comments: This tool would be great to use to quickly calculate a regression line or to find things like mean, SD, covariance, correlation, and the least-squares line. |

What math does one need to know to use the resource? You don't have to know any math. You just plug the numbers from the list in, and it automatically spits out all of the data that you need. |

What hardware expertise does one need to learn to use the resource? Nothing. It is compatible with any computer program. It is quick and easy to use, and it is much more user-friendly than a calculator. |

What extra things must be done to make it work? Nothing. |

How hard was it for you to learn? Easy |

Explanation: You just click and drag, and it gives you all of the information that you need. Also, there is a fairly decent page of directions if you need them. |

Ability to meet my goals: Very Effective |
