What is a matched pairs design example?

Each pair is matched on gender and age. For example, Pair 1 might be two women, both age 21. Pair 2 might be two men, both age 21. Pair 3 might be two women, both age 22; and so on.Click to see full answer. Likewise, what is a matched pairs test?The matched-pair t-test (or paired t-test or paired samples t-test or dependent t-test) is used when the data from the two groups can be presented in pairs, for example where the same people are being measured in before-and-after comparison or when the group is given two different tests at different times (eg.Likewise, what are matched samples in statistics? Matched samples (also called matched pairs, paired samples or dependent samples) are paired up so that the participants share every characteristic except for the one under investigation. A common use for matched pairs is to assign one individual to a treatment group and another to a control group. Besides, why is matched pairs design good? The goal of matched pair design is to reduce the chance of an accidental bias that might occur with a completely random selection from a population. Suppose, for example, we wanted to test the effectiveness of some drug on a group of volunteers.What are two types of matched pairs used in experiments?Either each unit/subject received both treatments, or one of each pair of units/subjects receives treatment A and the other receives treatment B. neither the subjects nor the people recording the observations knows which subject received which treatment.
