Confidence Interval Flashcards
1
Q
Confidence interval
A
This means that if the same study was repeated time and time again then the mean value would be within this interval 95% of the time. It does not mean that there is a 95% chance that the interval contains the true mean.
2
Q
True value
A
The ‘true value’ is the mean value that would be calulated if we had the data for the whole population (remember statistics are estimates for populations)
