A pharmaceutical company is testing a new medicine to treat high cholesterol. They want to see whether the new medicine does a better job of lowering total cholesterol levels than the standard treatment. To test the medicine, they started with 100 people with similarly high total cholesterol levels. Fifty people were treated with the new medicine, and 50 people were treated with the standard treatment. Both groups of people were treated for six months, and their total cholesterol levels were monitored.

What is the dependent variable?

A scientist wanted to know whether training in high altitudes increases a sprinter’s speed. The scientist trained six sprinters at high altitudes for six months and six similar sprinters at normal altitudes for six months. Both sets of sprinters were given equivalent training. Their fastest sprint times were measured for each sprinter.
