You might be off in your measurement by a beat or two, but if you have enough replicates then the average of those replicates will give you a reliable estimate. The experimental unit is the entity a researcher wants to make inferences about (in the population) based on the sample (in the experiment). I am definitely a SimBio fan!. Therefore in the experiment described there is only one replication; a situation often described as an un-replicated study. A farmer who grows blackberries has found his harvest to be lower than usual He suspects that some animals are eating the berries before he can pick them The farmer thinks it may be either birds (landing on the bushes to feast on berries) or rodents (climbing the bushes from below to munch on berries) He decides to first test the hypothesis that experiment is challenging, time-consuming, and expensive. A hypothesis is the correct answer to a scientific question. Here is a 5-item Gradebook Checklist to get your final grades ready!

Question: Question 3 (0.4 points) Which of the following statements about good experiments is TRUE? A well-replicated experiment ensures that the effect of one thing (the independent variable) on the other (the dependent variable) is real, true, reliable, valid. A variable is any part of the experiment that can vary or change during the experiment. They just think its fun.
