Before a client proposes or designs a research project, our team helps clients determine the desired total sample size and sub-group sample sizes to statistically sound comparison. In addition, we conduct power analysis to optimize the sample size recommendations according to the types of analytical techniques to be performed using the research data.
Luth Research can also assist in recommending the proper sampling method and design by utilizing SurveySavvy™, the company’s online community, and/or external sample sources. For research projects that require a representative sample, Luth establishes sample quotas to closely mirror the Census statistics.
When warranted by the research situations, we will also perform weighting of the data to reflect the true population parameters in demographics, as well as known product or service usage characteristics. Conducting this weighting allows you to gain an in-depth look at the data for population projection in new product development, brand audit or market share benchmarking.
