They had 2,000 data points... so they looked at the proportion of points on a given day when there was a report card released the previous day and when there wasn’t. Assuming Saturday’s accounted for, let’s say 20% of the population (blindly assuming) then they had about 400 data points and got a p value of 0.02. I’m assuming they did something to normalize for the number of days because there’s going to be far fewer report card days... idk. I think their statistics are probably shaky. Their confidence interval places the effect size at (20% to 1100%) if I’m reading correctly. I might believe that report cards increase rates of abuse but the idea that Friday is something special is probably just due to not having enough data for other days.

Perhaps, but a report card is likely to get more attention on a Friday than another day of the week, and I could see consequences stretching into the weekend, which is supposed to be a time for a child to relax from the school week. That being said, I think we should put far less emphasis on grades and report cards in general, so I'd rather just not give out report cards on a regular basis. Grades and reports cause a ton of stress for kids that just gets in the way of learning. I also think children should be allowed to go at their own pace and have some level of control over what they learn. It's okay if a child lags in one area and excels in another for a year or two. Interests change, and children learn far more rapidly in subjects they're interested in. I agree that just moving report cards may not solve the problem. We need to reexamine why we give report cards and decide if there isn't a better way (and there are a lot of alternative teaching methods that may do better than the way most public schools are run).

  Maybe, but, it’s not especially convincing evidence that this is a widespread problem. This is pure assumption, but if report cards effected rates regardless of day they probably would have mentioned this. We shouldn’t assume it is the case, and then even if it is the case, we should really take a hard look at whether is a meaningfully large number.

Seems ok to me but the usual problem as pointed by others whether other factors is in play, as most social studies do. Alcoholic Friday ...
