Specifying Answers for Simulated Data (SST)

Click here to learn more about Simulated Data (SST).

When running simulated data to test your project, you can specify which values to select at each question. If your survey has very strict logic or many terminate points, this will help you get more qualified completes from your simulated data runs.

The way you specify the answers depends on the question type. You'll find examples of each of the basic question types below.

1:  Single-Select Questions

1.1:  1-Dimensional

For single dimension radio questions like this:

We can specify which items to punch like this:

Q1: r2
Q2: r2 r3 r4 r5

When simulated data is ran, r2 will be the only punch made at Q1 and r2, r3, r4 and r5 will have a random distribution at Q2.

1.2:  2-Dimensional

For a two-dimensional radio question like this:

We can specify which items will be punched for each row individually like this:

Q1.r1: c1
Q1.r2: c1 c2

When SST is ran, c1 will be the only punch made at Q1.r1, and c1 and c2 will have a random distribution for Q1.r2.

2:  Multi-Select Questions

2.1:  1-Dimensional

For single dimension checkbox questions like this:

We can specify which items to punch like this:

Q1.r2: 100%
Q1.r3: 0%
Q2.r2: 50%
Q2.r3: 50%
Q2.r4: 25%
Q2.r5: 25%

When simulated data is ran, r2 will always be checked at Q1 and r3 will never be checked. r2 and r3 for Q2 will be checked for approximately half of the runs, and r4 and r5 will be checked for roughly a quarter of the runs.

2.2:  2-Dimensional

For a two-dimensional checkbox question like this:

We can specify which items will be punched for each row individually like this:

Q1.r1.c1: 100%
Q1.r1.c2: 0%

When SST is ran, c1 will always be punched for Q1.r1. c2 will never be punched.

3:  Text / Text Area / Number / Float Questions

The <text>, <textarea>, <number>, and <float> question types all work the same way in regards to specifying values for simulated data runs.

3.1:  1-Dimensional

For single dimension text questions like these:

We can specify the values to provide like this:

Q1: "Hello, world!" & '"quotes"'
Q2: 42 "foo" bars

The results are shown below when simulated data is ran. Notice that a single pair of quotes is not necessary, but you may specify two pairs of quotes if needed.

3.2:  2-Dimensional

For a two-dimensional text question like this:

We can specify which values to provide like this:

Q1.r1.c1: Hello World
Q1.r1.c2: ""

When simulated data is ran, Q1.r1.c1 will either be "Hello" or "World". Q1.r1.c2 will not have any values provided.

4:  Select Questions

4.1:  1-Dimensional

For single dimension select question like this:

We can specify which items to choose like this:

Q1.r1: ch1
Q1.r2: ch2 ch3

When simulated data is ran, Q1.r1 will always be ch1 and Q1.r2 will either be ch2 or ch3.

 

4.2:  2-Dimensional

For a two-dimensional select question like this:

We can specify which items to choose for each row individually like this:

Q1.r1.c1: ch1
Q1.r1.c2: ch2 ch3

Similar to the previous example, when simulated data is ran, Q1.r1.c1 will always be ch1 and Q1.r2.c2 will be either ch2 or ch3.
