What is precision measure?

Precision measurement is that which has maximum uncertainity


What does precision in science terms mean?

If you are trying to ask "what does precision in science mean" then I can begin to answer your question. Precision in measurement is a way of deciding how accurate a measurement is. If I were to measure my height with a ruler stick and a pencil against a wall I would expect the measurement to be accurate to a few millimetres. This is usually expressed in scientific terms as "plus or minus" so many millimetres. It is considered unscientific and unfair to describe measurements you may make in scientific work to a greater precision than you can actually make. I am about 5.9 metres (+- 1 cm) but it would be inaccurate and unscientific to say that I was 5.9354 metres tall. JCF


Use an example to explain how the available tools can affect the precision of a measurement?

Let's take the example of measuring the length of an object using two different tools: a ruler and a tape measure. The ruler has markings in millimeters, while the tape measure has markings in centimeters. If we use the ruler, we can read the measurement more precisely as we can estimate the length between the markings in millimeters. However, with the tape measure, we can only estimate the length between the centimeter markings, which is less precise. Therefore, the available tools have a direct impact on the precision of the measurement.
