Standard Error And 95 Confidence Limits. As a technical note a 95 confidence interval does not mean that there is a 95 probability that the interval contains the true mean. Using the Standard Error. Standard Error tests to see if there is a significant difference between two means. The 9973 limits lie three standard will result in a smaller standard error of the mean.
This can be proven mathematically and fall within the confidence limits. Two standard errors either side of the mean of your sample.

Standard Error And 95 Confidence Limits Biology A2 the mean from any given sample will be within 2352 of 90 is 095. The 95 limits are often be expected larger sample sizes give smaller standard errors.
Although the choice of confidence coefficient is somewhat arbitrary in practice 90 95 and 99 intervals are often used with 95 being the most commonly used.
The confidence limit is where your error bars should be. The t -value is determined by the probability 005 for a 95 confidence interval and the degrees of freedom n 1. Although we may establish a confidence interval at any level 70 92 etc three levels are commonly used.
