What is The percent difference between an observed value and its actual value?
It is the observed error.
What is the difference between the stochastic error term and the residual?
the residual is the difference between the observed Y and the estimated regression line(Y), while the error term is the difference between the observed Y and the true regression equation (the expected value of Y). Error term is theoretical concept that can never be observed, but the residual is a real-world value that is calculated for each observation every time a regression is run. The reidual can be thought of as an estimate of the error term, and e could have been denoted as ^e.
What is an absolute personal equation?
An absolute personal equation is the difference between an observed value and a standard value assumed as being true.
How can you calculate the difference between measured and calculated value?
A simple subtraction. Take the smaller from the larger
What is the difference between observed most probable and true value of a quantity?
The difference between the observed and the true value is the error. The most probable value depends on how it is defined and calculated. The maximum likelihood estimate (MLE) is often used but there are situations where it is not the most probable. For example, you are in a town where the bus routes are numbered sequentially. You want to know how many routes there are and so you observe the route numbers on a sample of buses. The MLE is the largest number that you observe but, in reality, there is no mechanism that will ensure that the bus with the largest route number is in your sample.
What is The percent difference between an observed value and its actual value?
It is the observed error.
What is the definition of percent deviation?
Percent deviation is a measure of the difference between an observed or measured value and a true or accepted value, expressed as a percentage of the true value. It is calculated by dividing the absolute difference between the two values by the true value, then multiplying by 100. Percent deviation helps to quantify the accuracy or precision of measurements.

What is the difference between 11 degrees and -6.5 degrees?
The difference between 11 degrees and -6.5 degrees is 17.5 degrees. This is calculated by subtracting the lower value (-6.5) from the higher value (11) to find the absolute difference between the two temperatures.
How do you find absolute discrepancy...this is different from percent discrepancy?
Absolute discrepancy is the absolute difference between an observed value and a theoretical or expected value. To find absolute discrepancy, you simply subtract the observed value from the theoretical value and take the absolute value of the result. This measurement is different from percent discrepancy, which calculates the difference as a percentage of the theoretical value.
How do you calculate the deviation?
Deviations are calculated from some value: the mean, the median, the maximum or whatever. You subtract that value from each observed value.
What is the chi square test used for?
The chi-squared test is used to compare the observed results with the expected results. If expected and observed values are equal then chi-squared will be equal to zero. If chi-squared is equal to zero or very small, then the expected and observed values are close. Calculating the chi-squared value allows one to determine if there is a statistical significance between the observed and expected values. The formula for chi-squared is: X^2 = sum((observed - expected)^2 / expected) Using the degrees of freedom, use a table to determine the critical value. If X^2 > critical value, then there is a statistically significant difference between the observed and expected values. If X^2 < critical value, there there is no statistically significant difference between the observed and expected values.
What does the term percent error refer to?
An error is the difference between a predicted value and the actual, observed, value. The percent error tells the user how close or how far off one was from the actual value in the form of a percentage.
What is the measure of quartile deviation?
A quartile deviation from some specified value, is the value or values such that a quarter of the observed values fall between these values and the specified value. Usually, but not always, the specified value is the median - the value such that have the observed values are below (and above) it. In that case, one quartile values will have a quarter of the values below it and the other will have a quarter of the values above it. The quartile deviations will be the differences between median and the two quartiles just calculated.
