Which of the following is true about the After-Only Experimental Design?
It satisfies some conditions for causality
Which is considered the gold standard for determining causal inference?
Randomized experiments
Which of the following is not necessary to determine that a marketing campaign causes an increase in sales?
We find that there are other external factors that affect sales but not the marketing campaign
Consider the following scenario. All chain restaurants had to put calories on their menus in he United States by December 2016. Researches measured receipts the month before and the month after this happened o test whether calories on menus effectively reduced overall calories consumption and / or reduced restaurant sales. This was an example of what kind of study?
Natural field experiment

Consider the after-only experimental design. Which of the following is true?
An advantage of this design is that there is no pre-test bias
Consider the before-and-after experimental design. Which of the following is true?
A disadvantage of this design is that there is pre-test bias
An example of a randomized, controlled experiment which is not an A/B Test is
A laboratory experiment in the non-digital world
Consider that a company wants to run an experiment to see which of four advertisements is most effective for a new product presented with five distinct price points. People are randomly assigned to see one of the four advertisements and one of the five price points. How many factors are part of this design?
