In a persuasive essay can you make up data?
It really depends who's reading it. I mean no teacher will EVER endorse lying but if you're writing this for a district essay then as long as you make it sound reasonable no one will call you out on it
it would be persuasive but would also be fraudulent. no. data is data.
not really, you need to back up your opinion with hard answers and people will always check your references/hard data
