Digital experiments can help us identify mechanisms in two ways.
Figure 4.19: Schematic of cost structures in analog and digital experiments.
In digital experiments, however, there are often many more participants and more is known about them.
Figure 4.18: Schematic of cost structures in analog and digital experiments.
This change in scale is because some digital experiments can produce data at zero variable cost.

In conclusion, digital experiments can have dramatically different cost structures than analog experiments. .
Even if you don't work at a big tech company you can run digital experiments.
In between these two extremes, there are partially digital experiments that use a combination of analog and digital systems.
But, if you donâ€TMt work at a tech company you might think that you canâ€TMt run digital experiments.
The different cost structures mean that digital experiments can run at a scale that is not possible with analog experiments. .
With that background,I will describe the trade-offs involved in the two main strategies for conducting digital experiments.
In between these two extremes there are partially digital experiments that use a combination of analog and digital systems for the four steps.
With that background,I will describe the trade-offs involved in the two main strategies for conducting digital experiments.
Even though digital experiments have low variable costs, you can create a lot of exciting opportunities when you drive the variable cost all the way to zero.
This point is so important,I will return to it towards the end of the chapter when I offer advice about creating digital experiments.
This background information, which is called pre-treatment information,is often available in digital experiments because they are run on top of always-on measurement systems see chapter 2.
But in digital experiments, particularly those with zero variable cost, researchers don't face a cost constraint on the size of their experiment, and this has the potential to lead to unnecessarily large experiments. .
Thus, I expect that construct validity will tend to be a bigger concern in digital experiments than in analog experiments. .
What has changed, however,is that the data environment in digital experiments has created new opportunities such as using machine learning methods to estimate heterogeneity of treatment effects Imai and Ratkovic 2013.
The paper-which originally had the provocative title"On the Near-impossibility of Measuring the Returns to Advertising"-shows how difficult it is to measure the return on investment of online ads,even with digital experiments involving millions of customers.
As I described in Chapter 5,researchers can increasingly design and build digital experiments with zero variable costs, a cost structure that enables extremely large experiments. .
Their paper-which originally had the provocative title“On the Near-Impossibility of Measuring the Returns to Advertising-shows how difficult it is to measure the return on investment of online ads,even with digital experiments involving millions of customers.
To foreshadow an idea that will come later when I offer advice about designing digital experiments, a_mixed design_combines the improved precision of within-subjects designs and the protection against confounding of between-subjects designs figure 4.5.
In general, analog experiments have low fixed costs andhigh variable costs whereas digital experiments have high fixed costs and low variable costs.
To foreshadow an that will come later when I offer advice about designing digital experiments, there is a final design, called a mixed design, that combines the improved precision of within-subjects designs and the protection against confounding of between-subjects designs.
In general, analog experiments have low fixed costs andhigh variable costs, and digital experiments have high fixed costs and low variable costs Figure 4.18.
In general, analog experiments have low fixed costs andhigh variable costs, while digital experiments have high fixed costs and low variable costs figure 4.19.
It is tricky to offer a formal definition of this dimension, buta useful working definition is that fully digital experiments are experiments that make use of digital infrastructure to recruit participants, randomize, deliver treatments, and measure outcomes.
