Estimate the mean value of a continuous measurement using a single sample.

Instructions: Enter parameters in the red cells. Answers will appear in blue below.

N = Sample size
m = Sample mean
S = Sample standard deviation
CL = % Confidence level

Standard error of the mean = SEM = S/√N =

t(α, N-1) =

Confidence interval = m +/- (t(α, N-1)*SEM)

Mean =
