With COVID, I'm spending a lot more time at home and I have been wondering whether to do some online courses to put on my CV. However, I'm not sure if the courses are worth the time and effort or whether they would just get ignored.
For example, I work in research and I could do with improving my statistics knowledge so I have identified a few free statistics courses that look really good. Would it be worth doing one of them and putting it on my CV or are they not really well-regarded? Is it worth paying the £60+ to get a certificate?
