How do you record a measurement?
Recording Measurements on the Data Collection Sheet
- Immediately record the measurement after it is read. Call out the measurement continuously until you have recorded the measurement.
- Record the measurement directly onto the sheet.
- Record measurements clearly and neatly, the same way every time.
What do you record in a valid measurement?
In a valid measurement, you record (zero, one, two) estimated digit(s). b. In a valid measurement, the estimated digit is the (first digit, second to last digit, last digit) in the measurement.
When reading a measurement scale explain how you should record a measurement?
When recording measurements, always record one decimal place past the smallest division on the scale, even if the number is a zero. This process ensures that all the certain digits, plus one uncertain or estimated digit is recorded.
How do you record a measurement including an estimated digit at the end?
When recording a measurement we include all of the known digits plus a final estimated digit. It’s sometimes easier to think of this in terms of recording all of the known “places” (ones, tenths, hundredths) plus a final estimated place.
How many estimated digits are usually in a measurement?
In 5.89 cm, the 9 is the estimated value. Therefore, this measurement has three significant digits, two that are certain and one that is uncertain (an estimate). Measurements have a certain number of significant figures or values that tell you about the measuring device.
How do you report significant figures?
The better rule is to report rounded up to one significant digit, which works across the spectrum of values. Thus a decimal places rule that ignores significant digits does not work.
What’s the best way to record a measurement?
Record the measurement directly onto the sheet. The more times the measurement is copied, the more chances of error there are. Record measurements clearly and neatly, the same way every time. Check to make sure it is accurate and legible. The chart below shows how to write numbers that are easy to read.
Why is it important to record body measurements?
Keeping a health journal, taking measurements and recording body changes over time is an important part of your training. It builds motivation, shows what progress you’re making, is useful for goal setting and can help you make insightful judgements about what works (and doesn’t) for you.
How do you find the reading on a measuring tape?
If the reading falls exactly between two of the 1/8 inch lines, randomly select either the higher or lower 1/8 inch number. Use the 1/2 inch line to help identify a reading. For example, the reading on the tape below is 44 3/4 inches, since the arrow is a little more than 1/4 (2/8) inch above the 1/2 inch line.
Do you need a tape measure to measure your body?
All you need is a tape measure! While it’s easiest to have someone else take your measurements, it can be done by yourself. Just stand in front of a mirror so that you can see that you have the tape in the right position. Ideally, you should be measured wearing only your undergarments. However, a leotard or close-fitting clothing will be fine.
