We’ll begin with the Y3: scale analysis, which is a visual assessment of the yolk set level on a scale of 1 to 16. The higher the score on the scale, the more set the yolk. In our case, values \u200b\u200bfrom 5 to 10 indicate a perfect yolk, below 5 indicates undercooked yolk, and above 10 indicates overcooked yolk.<\/p>

The DoE analysis for Y3 will involve answering the following questions:<\/p>

1. Which factors created the variation in Y3: scale? Which ones would we consider active?<\/strong><\/p>

To answer this question, we use a Pareto chart, expert knowledge, and\u2014in the case of fractional experiments, such as in this DoE\u2014we must remember the alias structure.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The Pareto chart above shows statistically significant effects. However, it’s important to remember that statistics are only a guide. Which effects we consider to be creating variation in this DoE should be determined by their practical significance, i.e., the magnitude of the effects. The magnitude of the effect indicates the potential to influence the analyzed Y.<\/p>

In our case, for example, the effect D is 7, meaning that changing factor D from the tested level of -1 to +1 shifts the position on a scale of 1 to 16 by 7 places.<\/p>

In this DoE, due to the magnitude of the effects, two main effects are active:<\/p>
