Document Summary
Measured-response experiment (design p68 2nd paragraph, example procedure. Vary the level of factor being tested and measure a response. Alternate/null hypotheses (p63): scientific name/abiotic factor testing/how response is measured e. g. caloric intake does affect the activity level of mice, mus musculus, as measured by the rate of movement on an exercise wheel. Studies show that mice typically require about 10 calories/day but cansurvive on as few as when the animal has freedom of movement. Three treatment levels including the control, be at equal increments throughout the range. 7 calories/day: 7, 10, amd 13 calories/day is better than 7, 8. 5, and 10 if 13 calories/day is not a lethal treatment, b/c it"s broader and the different treatment levels are more likely to produce different responses. Treatment control, used to compare with the results for each of the other treatment levels the treatment control eliminates that factor then the control is the most commonly found treatment in nature (called reference treatment)
