To find the ideal temperature for baking muffins, a student plans an experiment to assess the taste and texture of muffins baked at different temperatures. The student pours 3 batches of muffins from the same batter into baking cups and assigns them to different oven temperatures: 350 degrees, 375 degrees, or 400 degrees. Each batch is baked for 10 minutes, and after appropriate cooling time, the muffins are assessed for taste and texture.
B
the 3 batches of muffinsD
the taste and texture of the muffinsThe independent variable is the factor the student deliberately changes. Here, the student bakes the batches at 350, 375, or 400 degrees, so the baking temperature is the independent variable. The taste and texture are measured outcomes, while the baking time is kept the same.
