[Does not answer the question - PUPELLO]

18261216 — 2025-09-30 16:46:11 UTC

It has to be the exact measurements to be able to measure things right.

[Clarify - PUPELLO)

1157115 — 2025-09-30 16:47:50 UTC

A single measurement isnt enough to determine precison because you have to do more than one measurement to see how many times you made it in or how many times it came close.

185330_5 — 2025-09-30 16:49:07 UTC

precision describes the consistency or repeatability of measurements, which requires a series of results to compare

[Does not answer the question - PUPELLO]

176678_7 — 2025-09-30 16:50:36 UTC

Because single measurement would have higher chances of being inaccurate compared to doing multiple tests and comparing.

F

2025-09-30 16:53:33 UTC

114108_9 — 2025-09-30 16:55:25 UTC

A single measurement can’t determine precision because precision refers to how consistently you can repeat a measurement. One value doesn’t tell you if your measurements are close to each other; you need multiple measurements to see if they cluster together, which shows the reliability and repeatability of your method. Without several values, you can’t judge how accurate or dependable the process is.

False

114108_9 — 2025-09-30 16:55:38 UTC

False

114108_9 — 2025-09-30 16:55:49 UTC

[Does not answer the question - PUPELLO]

1141132 — 2025-09-30 16:57:03 UTC

To determine precision , you need at least a few measurements so you can see how much they vary.

[Clarify - PUPELLO]

1784771 — 2025-09-30 16:57:09 UTC

because precision is multiple chances and measurement is basically accuracy. +1 for participating.

Response

195588_2 — 2025-09-30 17:03:27 UTC

As Precision is when Measurements are close to one another but not necessarily the exact spot.

[Clarify - PUPELLO]

2025-09-30 17:03:31 UTC

the reason why 1 measurement is not enough lets say you toss a football you throw with precision but has bad accuracy to fix the accuracy you need to make another measurement for it to get better

213538_10 — 2025-09-30 17:19:13 UTC

It depends on the situation either you have to put power into something shoot.

[Does not answer the question, Clarify - PUPELLO]

176449_6 — 2025-10-03 16:33:36 UTC

if you want a percise measurement multiple sizes of measurment is most effiective

2025-10-07 15:46:59 UTC

[Clarify -PUPELLO]

2025-10-07 15:50:48 UTC

to be precise you want to have multiple means of measurement

[Reasoning is incorrect - PUPELLO]

2025-10-07 15:51:40 UTC

8.25 because it has inches and cm

[Incorrect - PUPELLO]

176449_6 — 2025-10-07 16:38:27 UTC

in this case we round down to 8 inches so we have an measure ment that makes more sense.

[Clarify - PUPELLO]

1157115 — 2025-10-07 16:41:56 UTC

I'd say 8.25 inches is more accurate because a measurement won't always be at just one number, it shows more detail.

[Incorrect - PUPELLO]

213538_10 — 2025-10-07 16:44:14 UTC

8 inches is more accurate because it's 100% than going over the goal you want it.

[Incorrect - PUPELLO]

114108_9 — 2025-10-07 16:44:48 UTC

8 inches because 8 inches only reports to the nearest whole inch.

[Incorrect - PUPELLO]

176678_7 — 2025-10-07 16:47:47 UTC

It depends on the experiment or what is being measured. If what ever is being measured ends in a decimal then that is more accurate and vice versa

[Clarify - PUPELLO]

18261216 — 2025-10-07 16:50:57 UTC

8.25 inches is more precise because it has a more precise accuracy.

[Clarify - PUPELLO]

2025-10-07 17:00:07 UTC

8 inches is more accurate because 8.25 is a decimal

one measurement is not enough because precision will not hit the mark on the dot
