At its simplest form, weighting/balancing allows you to adjust the data to account for sample bias. Sample bias occurs when your survey data (from your sample) does not accurately represent your target audience. Lets say for example, you are in the business of selling mens clothing. You also know that males form 80% of your customer base and purchasing decision. If you field a survey, and your survey response has 50% male and 50% female - you have sample bias. The data is leaning towards females, who constitute 50% of the survey data, but only constitute 20% of your customer base. Once, you've determined that you need to adjust for sample biasing, you need to weigh the responses and adjust the responses to this sample bias is eliminated.
Weighting and Balancing from Survey Analytics allows you to accomplish this.
