Measurement equivalence in mixed mode surveys

Measurement equivalence in mixed mode surveys

Surveys increasingly use mixed mode data collection (e.g., combining face-to-face and web) because this controls costs and helps to maintain good response rates. However, a combination of different survey modes in one study, be it cross-sectional or longitudinal, can lead to different kinds of measurement errors. For example, respondents in a face-to-face survey or a web survey may interpret th...

Using equivalence testing to disentangle selection and measurement in mixed modes surveys

Measurement Equivalence of Web Surveys Based on Social Media

Web surveys have become a very important way of empirical research. The rise of social media provides a new platform for web surveys. Investigators can collect data based on different social media platforms to get more respondents of higher external validity at a lower cost. However, there is no domestic expert and scholar to conduct related researches on web surveys based on social media. This...

Disentangling mode-specific selection and measurement bias in social surveys.

A large-scale mixed-mode experiment linked to the Dutch Crime Victimization Survey was conducted in 2011. The experiment consisted of two waves; one wave with random assignment to one of the modes web, paper, telephone and face-to-face, and one follow-up wave to the full sample with interviewer modes only. The objective of the experiment is to estimate total mode effects and more specifically t...

Balunless measurement of mixed-mode scattering parameters

Significance of sdd21 in HF technology Increasing data volumes, as well as enormous increases in transfer speeds, place high demands on the signal quality. This is especially evident with the current interface USB 3.0, which is also known as SuperSpeed because of its transfer speed of 5 Gbps. While a common mode inductor was adequate for the previous version USB 2.0 with 480 Mbps to guarantee s...
