I found the system complicated for someone not very experienced with computers. I still do not know how to find, on your system, the forms that I have completed. Where are they? How do I save them to my computer? I will keep working to find the answers.

It has been a little difficult at times but I am computer illiterate so if I can do it or manage to figure it out I think it’s safe to say anyone’s name.

I love to be able to use the pdf filler app much easier and it has become very important for us in documents we need to fill out and sign and send. I would like to see some ease in the selecting the editing of a document, can the display of boxes for each section be less overlapping each other, this may be difficult to do. Sometimes when you have a saved pdf document you do updates rather than create a whole new document, we use them as templates. Right now the easiest way is to create a document in Word, save it as a Word doc and as a PDF doc. Which is okay, often, time is a factor and to quickly update a pdf file would be faster. Thanks for listening.

Easy to navigate and use. Super quick and convenient when having to send completed forms for work or doctors appointments, especially if you do not have a printer/scanner.

I signed up originally to utilise this service. Whilst I did not wish to continue with the service (just wouldnt need it again) I did struggle to cancel the service. I sent an email outlining my issue and got the quickest response back and my account fixed and funds returned. Great service if you do require all the time. Easy to use. Highly recommend.

The experience is great because there…
The experience is great because there have been some documents that I needed to change, but for the free trial I wasn't expected to get charged at all. It's free for a reason. That's all apart from that, it's a great tool to have.

How do you determine the uncertainty of a measurement?
(5 cm ±. 2 cm) + (3 cm A. 1 cm) = (5 cm + 3 cm) A (. 2 cm +. 1 cm) = 8 cm A. 3 cm.
How do you determine the uncertainty of a measuring instrument?
measurement = (best estimate ± uncertainty) units. Relative Uncertainty = uncertainty. Measured quantity. Relative Error = measured value expected value. Expected value. (4) Measurement = (measured value A standard uncertainty) unit of measurement. (5) Average (mean) = (6) Average = (7) d = (8) s =
How do you calculate uncertainty in volume?
Volume: V’M/ M: mass. density. Accordingly, the uncertainty of the volume is determined by the uncertainty of the mass measurement and the uncertainty of the density determination, meaning that the factors constituting the uncertainty accrue at the time of each physical quantity measurement.
What is a random uncertainty?
Random uncertainties occur when an experiment is repeated and slight variations occur. They can arise due to measurement techniques or experimental design. The mean of a set of readings is the best estimate of a 'true' value of the quantity being measured.
How do you calculate random error?
To identify a random error, the measurement must be repeated a few times. If the observed value changes apparently randomly with each repeated measurement, then there is probably a random error. The random error is often quantified by the standard deviation of the measurements.
How do you calculate random uncertainty in Excel?
Open an Excel spreadsheet. Type the Excel formula for standard deviation in an empty cell. Plug your data range into the formula. Hit Enter or Return. Type the Excel formula for standard error value in another cell. Plug your standard deviation cell number into the formula.
What does uncertainty in measurement mean?
In metrology, measurement uncertainty is the expression of the statistical dispersion of the values attributed to a measured quantity. Thus, the relative measurement uncertainty is the measurement uncertainty divided by the absolute value of the measured value, when the measured value is not zero.
How do you measure uncertainty?
(10 cm ±. 4 cm) — (3 cm A. 2 cm) = (10 cm — 3 cm) A (. 4 cm +. 2 cm) = 7 cm A. 6 cm.
