In anexperiment, data from an experimental group is compared with data from a control group. These two groups should be identical in every respect except one: the difference between a control group and an experimental group is that the independent variable is changed for the experimental group, ...
aNo significant differences were found between the control group and the experimental groups for Activities of Daily Living (Barthel Index) or overall motor function (Rivermead Mobility Index). Although significant differences were seen in patients emotional status for a variety of tests。 重大区别未被...

The standard method for selecting experimental animals for control and experimental groups is by a randomization process in which each animal is placed into one of the groups without looking at any of its individual differences. An alternative, active matching process is proposed by which three to ...

If propensity scores are created from relevant covariates, matching on the propensity score makes treatment assignment ignorable and approximates a true experimental design. We illustrate how matching on the propensity score can be applied by using 2 examples: examining the effects of online instruction...

Control groups are not necessary for all scientific experiments. Controls are extremely useful when the experimental conditions are complex and difficult to isolate. Example of a Negative Control Group Negative control groups are particularly common inscience fair experiments, to teach students how to id...
