What would a sampling error of zero mean?
The sampling error is the error one gets from observing a sample instead of the whole population. The bigger it is, the less faith you should have that your sample represents the true value in the population. If it is zero, your sample is VERY representative of the population and you can trust that your result is true of the population.
What would it mean If the sampling error was zero?
The sample consisted of the entire population.
When could the sampling error be zero?
I believe you are considering the sampling error as calculated from data. I will give you some examples: If you get the exactly same response from all participants in a survey, you will calculate zero sampling error. For example, if I ask 10 people if Obama Barack is the President of the US, I would probably get 10 "yes" responses. Now the answer was well known, so I would expect very few "no" response. If your measurements are not very sensitive or are recorded with a lack of precision, then there can be zero sampling error. For example, I take the body temperature of students at the college and consider any temperature from 97 to 99 degree F to be normal. I find all students in my sample have normal temperatures. So, zero sampling error can occur because a) sample is small, b) variation in response is either non-existent or very small. In theoretical calculations, where sample error is based on the probability distribution of the population, one can calculate for discrete variables, the probability that a sample error will be zero.
What does the sum of the deviations of each value from the mean equal?
The sum will be zero or close to zero, depending on how the sampling was done. See related question.
What error value indicates the formula is trying to divide by zero?
#DIV/0!
Zero error of a spring balance?
zerro error in a spring balance affects the accuracy in the weight. To find zero error in spring balance, you have to first find the least count of the spring balance and then suspend it freely, if the outcome is +1, the zero error is +1 and if it is -1 ,the zero error is -1.
Where does the value returned by the main function go?
The value returned by the main function is returned to the OS as the programs error number. An error number of zero usually indicates there is not an error but this is up to the programmer to decide.
How do you create an excel formula that divides two cell's but will not do so if the value being divided by is a zero?
Assuming that Excel's default DIV/0! error detection isn't enough for you... You could use the IF() operator to check the value of the divisor, and return something appropriate if it turns out to be zero.
What is a zero error?
if the zero line of vernier scale is not conciding with main scale the zero error exists.Knowing the zero error necessary correction can be made to find correct measurement..Such a correction is called zero correction
How you remove positive zero error?
Positive zero error means, instead showing zero it shows some value more than zero. Hence positive. Suppose if it shows some reading say 0.03 units. then while correcting we have to subtract the above from the observed reading. So correction is adding negative error.
What Excel displays in cells to indicate a divide by zero error?
#DIV/0! Microsoft Excel displays the #DIV/0! error when a number is divided either by zero (0) or by a cell that contains no value.
How do you find the zero error and zero correction in sgrew gauge?
we can find the zero error by closing the jaw of screw guage if the zero of main scale(MS) is concide with the zero of circular scale (CS) there is no zero error and if they are not concide there is a zero error in screw guage .
