1. Giving up density is a way to measure the conditions under which an animal is willing to experience risks in feeding. One way to approach an GUD experiment is to mix food in with inedible particles, then to measure what percent of the mix is food when an animal stops collecting or eating food. How could this method be used to study optimal foraging conditions? 2 wk
Which of the following statements is true of the relationship between sample sizes and effect sizes? The larger the true difference, the larger the sample size required to demonstrate superiority Small studies that ask the same research question are more likely to vary in their estimate of the between-group difference than large studies There is no relationship between effect size and sample size The bigger the expected effect, the bigger the required sample size
Mina is testing different types of heat lamps to determine which type is most effective for growing strawberry bushes. She purchases two different types of lamps from a local store. Mina applies brand A to one area of the yard and brand B to another area of the yard, both of which receive full sunlight. She waters the area with brand B daily; she waters the area with brand A every other day. At the end of the study, Mina concludes brand B is more effective in growing strawberry bushes. Mina's conclusion valid? Explain why or why not.
