Asking 4 raise Data Analyst 50k TC

50k TC rn because I had no experience in the role coming in I basically hustled this job. I just finished a 4 month training process. Since I started working I’ve taught myself Calc currently taking stats and SQL class. I’m going to ask for a raise at 6 months in. My team has been telling me I’m doing great so far. Average entry lvl data analyst salary is 58k and median is 74k according to google.(Also I did get a job offer for 60k a year but turned it down because it was a different role and I want to stay in data.) Yo how much should I ask for?
