Note: This page now accepts data where either a comma (,) or point (.) is used as the decimal separator.
Compare a sample mean (or median) to a population estimate (default 0) using the 1sample
ttest (or sign test for medians). Pvalues can be
calculated for one or twotailed comparisons, and are compared to a specified
significance level.
Inputs are:
 Population estimate of mean or median for comparison (default value is 0);
 whether to use ttest (means) or sign test (medians);
 specified significance level;
 number of digits to display in results;
 whether test is onetailed or twotailed; and
 sample data.
Outputs include:
 A summary of the data provided;
 Confidence limits (based on specified significance level) for the sample mean or median; and
 P values for the difference between sample mean/median and the specified value;
 interpretation of the results; and
 plots of the data distribution and confidence limits for mean/median.
