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.
What is the most accurate method used to determine where the maas trailers are positioned?
optical surveying instrument
What is the preferred and most accurate method used to align the MAAS trailers and LWFB?
optical surveying instrument
What is spot level in surveying?
Spot level in surveying refers to the process of recording the elevation at a specific point on the ground using a leveling instrument. This information helps in creating accurate topographic maps and is crucial for construction projects to ensure proper grading and drainage.
Is surveying still used?
Yes, surveying is still widely used in various industries such as construction, civil engineering, land development, urban planning, and environmental assessment. Surveying helps in determining property boundaries, creating maps, planning infrastructure projects, and collecting valuable data for decision-making. The advancement of technology, including GPS and LiDAR, has modernized surveying methods, making it more efficient and accurate.
Why is levelling important in surveying?
Leveling in surveying is important to get an accurate measurement. The rise and fall of the grade will cause the measurements to be off, resulting in an inaccurate measurement of plots of land.
Can an instrument be accurate and sensitive?
Yes
What are advantages of population census?
there is no way to find the diadvantages, but here is one. Using a population will get you an accurate answer of what you are surveying.
Why do scientists make measurements?
to find accurate information
What about collecting data most determines whether or not it is accurate?
Recording data properly.
What is a precision instrument?
Precision means accuracy. A precision instrument is a top quality one that is super-accurate. You can get an instrument that will just do the job, or you can spend extra money and get a precision instrument that will be perfect. Many measuring devices are precision instruments because they must be totally accurate.
What would a compass be used for?
Drawing accurate circles and part circles in surveying, mathematics and geometry in schools and at work where planning is involved.
What instrument gives the same reading each time it makes the same measurement?
A precise instrument. It is not necessarily accurate.
