Questions & Step-by-Step Solutions
If a measurement is said to have a precision of 0.01 cm, what does this imply? (2019)
Step 1: Understand what precision means. Precision refers to how close measurements are to each other.
Step 2: Recognize that a precision of 0.01 cm means the measurement can be accurate to two decimal places.
Step 3: Realize that this precision indicates the smallest difference that can be measured, which is 0.01 cm.
Step 4: Understand that if you measure something and get a value, it could actually be a little higher or lower by 0.01 cm.
Step 5: Conclude that the precision level shows the uncertainty in the measurement, meaning it is reliable within that range.
Precision – Precision refers to the degree to which repeated measurements under unchanged conditions show the same results, indicating the level of uncertainty in the measurement.
