May 30, 2022 · What is a matched pair microphone? A "matched pair" is a set of two microphones that sound the same. Our pairs are hand-matched for both sensitivity (0.5dB @ 1kHz) and frequency response (1.5dB, 50Hz–15kHz). Those specs are just a technical way to express that the two mics sound essentially identical. Matched pairs design Step-by-step explanation: A matched pair design can be used in a case where the same people are being measured in before-and-after comparison. The same set of people are measured for the amount of sleep each night before the administration of the drugs and after the drug administration and this is used to test for a difference.3 Completely randomized, blocked, and matched pairs design. ¶.

Matched pairs design works in 2 steps: Divide participants into pairs by matching each participant with their closest pair regarding some confounding variable (s) like age or gender. Within each pair, randomly assign 1 participant to either the treatment or the control group (and the other will be automatically assigned to the other group). Matched Pairs Design - uses only two treatments - each subject receives both treatments - subjects are matched in pairs as closely as possible - subjects are randomly assigned to each of the treatments (group 1 does treatment 1 first and group 2 does treatment 1 second) THINK twins experiment Completely Randomized Design The RCT-YES R package and documentation (Schochet, 2016) also provides a conservative variance estimator for the matched pairs design (as well as estimators for blocked designs); this is discussed more in onlineFor matched-pair designs, complete has to equal TRUE.
