"Points are determined (based) on the final results."

Is "based" mandatory?

 

[JTRiff]

In this example, yes, it is.

I'd need more context before giving a firm answer.

What are we talking about here?

"Costs will be determined based on design, construction bids and other factors."

 

[Rover_KE]

"Costs will be determined based on design, construction bids and other factors."

That's fine, but it's got nothing to do with your original sentence.

[ShirleyLing]

So, "based" is necessary?

 

[ShirleyLing]

A better example: "Scores are determined (based) on distance and accuracy for each event."

So is "based" optional here?

 

[Rover_KE]

I would say it's optional here.

What about the example in post #4 of this thread? Is "based" also optional in that example?

 

[Rover_KE]

I'd leave it in.

 

[ShirleyLing]

In post #4, "based" is mandatory in "Costs will be determined based on design, construction bids and other factors."

But in post #7, "based" is merely optional in "Scores are determined based on distance and accuracy for each event."

How can I tell when to leave out "based"?

 

[Rover_KE]

If in doubt, leave it in.

It will never be wrong.
