Question

assuming a %RSD of 2.5%, determine the uncertainty of your measurements. You may report your data to ±2 σ I only have one measurement... how do I do this?

Answer 1

then I don't know how can you have a standard deviation with just one measurement

Answer 2

that might be a trick question so you probably need to focus just with the uncertainty

Answer 3

well i have multiple measurement just not for the same thing. I'm not sure how to do it. here is the whole question.
Due to time constraints, you did not have the opportunity to run triplicate measurements, so assuming a %RSD of 2.5%, determine the uncertainty of your measurements. You may report your data to ±2 σ.

Answer 4

2.3 to 2.7

Answer 5

* \[\pm2\]

Answer 6

the uncertainty will have to be from the least number of digits then subtract and add the value you have

Answer 7

so I have a measurement for the concentration of F as 10.5883 for some unknown.

Answer 8

can you list all of your measurements?

Answer 9

This is all I have for that question:
Unknown B conc of F=10.5883
Unknown A conc of F=.5252
Unknown A conc of MFP=22.4079
Unknown B conc of MFP= 54.0488

Answer 10

do you understand where I'm coming from? I dont have enough data to get a standard dev or % RSD it was "given" to me. I don't understand how to report it this way when I don't have multiple measurements of the same thing.

Answer 11

@aum got any ideas?

Answer 12

I'm so confused
