Dominic and Eva are using the same type of stopwatches to measure the time it takes for a chemical reaction to occur. They each

use the same stopwatch to measure the time. These are their results:
Person Trial 1
Dominic 78 seconds
Eva 81 seconds

Why are their results unreliable and can lead to a pseudoscientific claim?
They did not repeat their tests multiple times.

They used the same type of stopwatch.

They did not change the reactants in their chemical reactions.

Only one person should have collected the data.

They did not repeat their tests multiple times is the answer.
