Our recent look at preparation times for Dalgona coffee produced data that lent itself to 2ᵏ analysis. However, a closer look at the collected data indicated that with a single extra trial we could compare the variation explained by instant coffee type and beater type.
Our recent investigation into the preparation time of Dalgona whipped coffee left us with a pile of timing data. Some of that data happened to be compatible with 2ᵏ factorial experimental design. So, why not complete the analysis and see what we find?
