I am a recent graduate from my university and my undergraduate degree is in Statistics. I really like Statistics, and possibly will try to make a living as a statistician. I am looking into a Master's program and I cannot stop myself from wondering if I need to take a Master's program in "Statistics" in order to become a statistician. If I, for instance, take a Master's program in "Educational Measurement/Statistics/Assessment", can I still be a statistician with that academic credential (given that I already have an undergraduate degree in Statistics)?
I took a look at the curriculum and the coursework includes Experimental Design, Regression, and Multivariate Analysis. I don't know if those courses have some considerable mathematical rigor though.
