To help out with your co-directorial debut, we've prepared a cross-section of the wedding day cast of characters. (Keep in mind that most roles can be played by either gender, and by as many people as you want.) This guy acts as groom's valet (personal aide and advisor) through all stages of wedding planning.
Implicit bias occurs when someone consciously rejects stereotypes and supports anti-discrimination efforts but also holds negative associations in his/her mind unconsciously.
Design bias is introduced when the researcher fails to take into account the inherent biases liable in most types of experiment. Some bias is inevitable, and the researcher must show that they understand this, and have tried their best to lessen the impact, or take it into account in the statistics and analysis. Another type of design bias occurs after the research is finished and the results analyzed.
