    I What is the correct definition of measurement uncertainty?

    Both your statements are absolutely correct , no doubt. But I meant there 'a very large number of measurements reflects the mathematical probability' e. g. Tossing a coin 2 times may result in one part ( head or tail ), 100% of time only one but if you increase number from 2 to 200 we would be...

    I What is the correct definition of measurement uncertainty?

    Now I am done with my doubts and I am posting what I learnt through your posts and a book half of which I recently completed : Taylor : An introduction to error analysis. That's a concept I was lagging with. I didn't know difference between Standard deviation of the mean (also know as standard...

    I What is the correct definition of measurement uncertainty?

    If it is not related to true or actual value of measurement then what's use of uncertainty in reporting a measurement.

    I What is the correct definition of measurement uncertainty?

    Would you like to suggest some good books or articles that deals with statistics in measurements.

    I What is the correct definition of measurement uncertainty?

    Edit:- In context of infinite measurements, I meant there a large number of measurements and I know infinite times is what not possible to measure that's why I have wrote there theoretically not practically. I wanted to know that for example what does population standard deviation in population...

    I What is the correct definition of measurement uncertainty?

    I have some confusion regarding Measurement Uncertainity. In some books/articles it is defined wrt true value as "Uncertainty in the average of measurements is the range in which true value is most likely to fall , when there is no bias or systematic component of error is involved in...

    I Measurement Error Analysis in Gaussian distribution

    Is this graph(below) I have made correct according to ISO definations? ( links of definations are provided in question)

    I Measurement Error Analysis in Gaussian distribution

    I am new to statistics and recently learned about ISO guidelines for Accuracy & Precision and Uncertainty & Error. But there are some graphs of probability distribution I found on internet which I am not able to grasp. image Source Q. In this graph(above) if...

    Gibbs free energy of activation and activation energy

    Let's consider a reaction A (reactant) -> B(product) and activated complex is denoted by C. This graph ( potential energy vs reaction coordinate ) tells us that reactant need some amount of activation energy (Ea) to convert in product, which has low potential energy which is shown here in...
