Can someone enlighten me as to why a study such as this one may be undertaken without a control group? I mean, what's the point? If the study ends up landing on some exciting conclusions, not having a control group creates more questions than answers. Is there a budgetary constraint at play here or are researchers sticking their feelers out in all kinds of directions simultaneously trying to figure out which direction may be the most promising?
- driverdan 7y agoBecause the larger the group the more expensive it is to run. This is a very early experiment to see if there's anything worth doing a larger study on.
- James_Henry 7y agoYes, this is very standard practice. You can still learn a lot with a small sample size and no control, especially when you don't know much. It's a big deal that they are able to see a full on reversal of Horvath's clock whether or not it was in a handful of people or a thousand!
