The script was originally designed to help teachers analyse their student marks.
Many teachers keep marks in spreadsheets, but don't have the time or expertise to insert formulas to perform all the statistical calculations.
Statistical calculator allows users to simple copy and paste their data, then calculate and print the statistics.
It is useful, particulary for moderation purposes where many teachers teach the same subject across a year level & for feedback purposes to students and parents.

Quadratic-O-Matic is about the simplest program imaginable to set up and to use. You simply call the program up in your web browser, type in the numbers to get your quadratic equation, and click "Solve that puppy." You will then be given the roots of the equation.

MetaboCalc uses the Harris-Benedict equation to give you an approximation of how many calories you burn per day and at rest. It shows the base number, and also plus and minus 5% and 20% due to errors inherent in that equation. Basically, this calculator is intended to show your RMR (Resting Metabolic Rate) or BMR (Basal Metabolic Rate). Actually, BMR and RMR are slightly different, but they're often referred to as the same thing, so we're not going to worry too much about that.

SFEBMICalc is a simple Body Mass Index calculator. If a user enters their height (in centimeters or inches) and their weight (in kilograms or pounds), the program will return their Body Mass Index. You can configure it so that either Pounds/Inches or Kilograms/Centimeters is the default, and even change the spelling of Centimeters if you like

VeryInteresting is a simple loan calculator. If a user enters a loan amount, an interest rate, the length of a loan, and the payment frequency, the calculator will show the monthly payment and the total interest that will be paid if the loan is paid to term. For monthly payments, it will also show an amortization table. This can be an exciting activity for students studying simple interest, as they can quickly change the number of years a loan is for or the interest rate and see the dramatic differences this makes in both the payment amount and the total amount paid in interest for a loan. If your local currency is not "dollars," you may choose from ?, ?, and ? for the symbol to show after monetary amounts.

AffordaBilly is a simple interest loan calculator, similar to "VeryInteresting" but focused on determining how large a loan the user can afford, given an interest rate and length of the loan in years. Users can choose monthly or bi-weekly payments. The results will show the maximum amount of a loan that the user can afford based on the monthly payment and interest rate. This is a very simple, yet nice educational tool for showing just how much only 1 or 2% interest can make a difference over the course of time. I think it's cool to have students calculate the loan they can afford with a monthly payment, then have them cut that in half and choose "Bi-Weekly". For example, over the course of a 30-year loan at 7% interest, a Bi-Weekly payment of 325 will let you afford about ,000, whereas a Monthly payment of 650 will only let you afford ,000. Take the interest from 7% to 8% over the same term, and you can only afford about ,000. And students wonder why they should care about interest rates and other math stuff? :-) AffordaBilly is a blatant ripoff of the VeryInteresting payment calculator, also available for download from this site.

PayBackTime is a simple perl/CGI interest loan calculator, similar to "VeryInteresting" and "AffordaBilly" but focused on determining how long it will take to pay off a loan or credit card, given a minimum payment, balance, and interest rate. The results will show the time it will take to pay off the balance with that monthly payment, number of payments, and the total interest the user will end up paying. For illustration purposes, it also shows the same data based on a bi-weekly payment of half the amount of the monthly payment. This is another very simple, yet nice educational tool for showing just how much only a few dollars a month can decrease the time to pay off a balance, and for showing just how much you pay for the privilege of using a credit card and paying the minimum payment. Most people simply don't think about how much they're paying, and this is a nice illustration. Students I've shown this to (and not just students, but most people) are often amazed at both the length of time it will take to pay the balance off, and by the amount of interest they will pay. PayBackTime is a blatant ripoff of the VeryInteresting payment calculator, also available for download from this site.
