BRAINLIESTTTT ASAP!!! PLEASE HELP MEEEE :)

Answer 1

Precise is the close proximity of repeated measurements.  In order to be precise, you need two or more measurements.

Accurate is the close proximity to the real (or expected) measurement.

For Example:

You are at the grocery store buying watermelons.  The sign says that the watermelons all weigh 2 lbs.  You weigh 3 of them on the scale next to the watermelon display.  Their weights are 1.77, 1.80, and 1.82.  

→ The scale is precise because it weighs all 3 of them at nearly the same value.

→ The scale is not accurate because their weights are not close to the expected value of 2.0

You take one of the watermelons to the cashier.  The scale at the checkout counter weighs it as 1.99.  The scale at the checkout counter is accurate.  You cannot determine the precision of the scale at the checkout counter because you have no other values to compare it to.

Answer:  Precise CANNOT be determined by one measurement.  

               Accurate CAN be determined by one measurement.
