Trial |
Trial number |
Two students, Lara and Lisa, conducted an experiment to compare Orville Redenbacher's Light Butter Flavor vs. Seaway microwave popcorn. They made 12 batches of popcorn, 6 of each type, cooking each batch for four minutes. They noted that the microwave oven seemed to get warmer as they went along so they kept track of six trials and randomly chose which brand would go first for each trial. For a response variable they counted the number of unpopped kernels and then adjusted the count for Seaway for having more ounces per bag of popcorn (3.5 vs 3.0).
