I'm super bad at stats and i rly need your help.

So here's the pb : i want to compare 2 different ingredients (Ingredient A/ ingredient B). Each ingredient is described by 4 independant quantitative variables.

I would like to know if these 2 ingredients are significantly different or not depending on these 4 variables.

How do i check if my data follows a normal distribution? Which test can i use when i have 4 factors ? I know how it works but with 4 factors i dont know which test use and on which data (can i check normal law on all of my data in 1 time or do i need to separate my data depending on the factor or something??)

What should i do? Which test should i use? I'm completly lost. I was thinking about Student test but i dont think its possible w 4 variables. What about ANOVA? Is it ok? ANOVA w 4 factors?

PLEASE PLEASE PLEASE HELP ME

THANKS TO ANY PERSON WHICH WILL HELP ME
