Question

@lgbasallote
Each of five students used the same ruler to measure the length of the same pencil. These data resulted: 15.33cm, 15.34cm, 15.33cm, 15.33c, 15.34cm. The actual length of the pencil was 15.85cm. Describe whether accuracy and precision are each good or poor for these measurements.

Answer 1

@anyone :)

Answer 2

not @saifoo.khan

Answer 3

okay.

Answer 4

accuracy is the consistency of the measurements

precision is the closeness of the measurements to the actual measurement

does that help?

Answer 5

i know that part but i still dont know how to answer this

Answer 6

saif....please -.-

Answer 7

15.33
15.34
15.33
15.33
15.34

are they close to one another?

Answer 8

accuracy is getting the answer right AT LEAST ONCE and precision is getting the same answer over and over again

this is what i have to go by (my teacher's notes)

Answer 9

really?

Answer 10

Answer 18

she said precision was getting the exact same answer over and over again

Answer 19

so this ones not accurate nor is it precise

Answer 20

but i still dont get what to write as an answer to the question... :\

Answer 21

actually precision is the closeness of the measurements to one another

Answer 22

accuracy is how close the measurements are to the true value

Answer 23

okay..i get that..so how do i answer?

Answer 24

precise but not accurate

Answer 25

So we don't have to find the average and then find the percentage error?

Answer 26

Describe whether accuracy and precision are each good or poor for these measurements.

Answer 27

@saifoo.khan the question didnt ask to so i guess not....theres another question on this worksheet that asks to do that, not this one

Answer 28

@lgbasallote the question asks: Describe whether accuracy and precision are each good or poor for these measurements.

how is that to be answered?

Answer 29

Ah, okay. It says "accuracy and precision"

Answer 30

like i said... precise but not accurate. how do you think you can use good and bad there?

Answer 31

i honestly actually dont get what the question wants

Answer 32

precise...not accurate

what does good and poor mean?

Answer 41

if it's precise..then is it good precision or poor precision?
