Re: [R] Simple Error Bar

Uh, no. You are forgetting to take the square root of 10, and to divide by the square root of 12. The variance of Y is (exactly) (56^2 - 1)/12, so the variance of Y-bar is this quantity over 10, so the standard deviation of Y-bar is sqrt((56^2 - 1)/12)/sqrt(10). Which is approximately (ig

[R] Simple Error Bar

Hi, Basic question with basic code. I am simulating a set of 'y' values for a standard 'x' value measurement. So here the error bars are very long because the number of samples are very small. Is that correct ? I am plotting the mean of 'y' on the 'y' axis. Thanks, Mohan x
