Suppose that we have an i.i.d. sample X1,...,Xn with some unknown distribution P and we would like to test the hypothesis that P is equal to a … A one sample t test compares the mean with a hypothetical value. In most cases, the hypothetical value comes from theory. For example, if you express your data as 'percent of control', you can test whether the average differs significantly from 100.
Single Sample T-Test Calculator A single sample t-test (or one sample t-test) is used to compare the mean of a single sample of scores to a known or hypothetical population mean. So, for example, it could be used to determine whether the mean diastolic blood pressure of a particular group differs from 85, a value determined by a previous study. vartestn(x,group,Name,Value) returns a summary table of statistics and a box plot for a test of unequal variances with additional options specified by one or more name-value pair arguments.

You can find all codes here. Say we have a function add_one.m we want to test:

vartestn(x,group,Name,Value) returns a summary table of statistics and a box plot for a test of unequal variances with additional options specified by one or more name-value pair arguments. For example, you can specify a different type of hypothesis test or change the display settings for the test results. One-sample or paired-sample Wilcoxon signed rank test. Tests if a sample comes from a continuous distribution symmetric about a specified median, against the alternative that it does not have that median. signtest: One-sample or paired-sample sign test.
