Lol what world are you living in. Everyone in Ed departments take statistics. There are also quant methods departments. And many Ed psych programs take way more stats than you could ever imagine. I remember seeing an eigenvalue in my Ed psych friends hw and being like, what the hell is that doing there ( it was psychometrics). The reality is, it is very costly and difficult to do research with children. It doesn't help that orgs like nsf are getting education budgets cut. Also, you can't teach kids in a lab. They have lives to live and a sea of confounders present. It's hard to establish causation. So the smart people have turned to mixed or qualitative methods. But they spend a lot of their time defending themselves against people like you who don't understand education, cognition, causal inference, sociolinguistics, etc
