Sample Selection

When selecting your sample, you must specify the country. You can add additional restrictions, such as age or education. You can add multiple segments and set quotas.

If you have previously run a similar study, you may re-use a Saved Twin Sample instead of building a new one. See Reusing Twin Samples.

Next, select your sample size. The default setting is 80, which allows you to capture more complex designs with several sub-groups. For simpler designs, you may choose to decrease the sample size.
