Do they still teach migration as a part of life sciences? Or is it just learning mantras by rote now?
(And why, when I ask for something called "evidence", I get the feeling that not a single evolutionist here knows what the word means? Do they still teach the means that geologists use to confirm continental drift, like the magnetization in minerals and the magnetic banding in the ocean floor and similar minerals across oceans? Again, atheists rely on belligerance, not intelligence. What should I think about them, except that they're not so far evolved beyond monkeys?)

The wages of an employee depend on the time worked. Time is the independent variable that varies among employees, and the wages are calculated directly from the total time worked. Thus wages are dependent on time worked
does that mean that time is also dependant?
A researcher is interested in examining the effectiveness of magnetic therapy for treating
chronic pain. A sample of n = 7 patients is obtained, each of whom has been treated for
severe elbow pain for at least one year. Each patient is given a questionnaire to assess his or
her current level of pain. The patients are then instructed to wear a magnetic band around
their elbows for two weeks. After the two week period, the patients again complete a
questionnaire evaluating their pain.
Whats the dependant and independant variables? no not homework, im studying and im confused. noone else to ask...
whats the null hypothesis, i know it means that its no difference between the means and what are alternate hypothesis??

Saw a doco that saw ppl trying to sell magnets that made ppl feel more stronger and energized. True? any references or summary of the refs. would be nice.

A few of my friends own Phiten and/or Power/Balance bands and swear by them. But I've looked into them and there is no scientific proof that they work. Can anyone give me an opinion and some sort of evidence to back it up? And also if there is some other band and the sort that you've found and that works, please tell me about it.
