Hey, I have a group of 60 people aged 50-94. Is this group considered to be homogenous or heterogenous?. Also is standard deviation 13,1 in this case high or low? mean is 70,45. thank you

I do not know whether that question makes much sense, at least when asked without
any hint about the context. Why do you want to label it as either homogenous or
heterogenous?
Also is standard deviation 13,1 in this case high or low?
I comparison to what?

With kind regards

Sorry, basically I had to do a seminar work in statistics. This is the data, but my teacher wants to also know if this group of people is homogenous/heterogenous in terms of age. And if this SD is low or high (that's what she asked me, I guess in comparison to average SD of age distribution?) Also what is the correlation between mean and SD. I hope it makes more sense now, I don't really know much about statistics. Thank you
