How can errors occur when collecting data?
One the biggest errors that could occur while collecting data is that people who are giving the information could not give accurate answers and the investigation could be jeopardized.
Can the last digit of a measurement using the verniercliper be estimated?
Yes, but then there is no point in using an instrument that is that accurate!
What is the difference between an error as a percentage of full scale or an error as a percentage of reading?
Error as a percentage of full scale is established by multiplying the error percentage by the full scale flow. The less you flow through the device the less accurate the reading will be. For that reason, you don't want to get a larger device than you need. Devices with error expressed as a percentage of full scale are most accurate when flowing at full scale.Error expressed as a percentage of reading expresses error as a percentage of what the device is actually flowing. Simply, if a instrument's accuracy is rated to +/-1% of reading an instrument will be accurate to +/-1% of whatever the instrument is flowing. At 100SLPM the instrument will be accurate to within +/-1SLPM, and at 10SLPM of flow the unit will be accurate to within +/-.1SLPM.
What is a digital caliper?
An extremely accurate device used as an instrument for measuring the distance between two points. Often used in machining.
What problems occur when collecting weather data manually?
You might receive anonymous results (incorrect data). By using Automated weather equipment, the results will be more accurate.
