  Honestly, there is are none lmao. Basic propositional logic just only allows us to represent it as (Earnings --> DP to hours worked). But, if it helps just do it as a ratio? So, Earnings : hours worked. Its better to represent it as a ratio if they give you numbers though.

  I suppose I'd use the generic proportionality symbol which can probably be best described as a ribbon-shape tilted onto its left side, or a greek letter alpha that has been squashed/stretched horizontally.

  Wait, what?? I actually use this! I thought I made it up though (clearly not, guess I'd just seen it before) 😂 It's like an infinity symbol with a bit of the right end cut off, right?

  Edit: Yep, I looked it up. So I would write "earnings is directly proportional to hours worked" as E ∝ HW.

  It's a correlation, so I just write a line in between them with 'Corr' on top of it. I'd avoid arrows since causality hasn't been established either way. Like in the example "The rate of ice cream consumption is directly proportional to the murder rate," where heat is the cause of both.

  Thx @LSATscrub
  A line with ‘corr’ Is very practical. I guess I can substitute ‘corr’ with any ‘x’ should I need to
