You can do a mail merge in Microsoft Word and Excel to create personalized documents for many recipients at once.
A Student's t-test is a statistical test to compare the means of two groups and see if they are significantly different. It is based on the t-distribution, which depends on the sample size and the variance of the populations. Learn about the history, types and uses of the t-test.
Mail merge is a feature that combines mail and letters and pre-addressed envelopes or labels from a form letter. It uses data from a source such as a spreadsheet or a database to replace variables in the template with personalized information for each recipient.
The t-statistic is a ratio of the difference in a number’s estimated value from its assumed value to its standard error. It is used in hypothesis testing via ...
Welch's t-test is a statistical method to compare two populations with unequal variances and possibly unequal sample sizes. It is an adaptation of Student's t-test and is more robust and reliable than the latter.
Equivalence tests are statistical methods to compare effects that are not expected to be zero, but small enough to be considered equivalent. The TOST procedure is a simple and popular approach that uses two one-sided t-tests to reject or accept the equivalence bounds.
Learn about different methods to test if a data set is well-modeled by a normal distribution, such as graphical, back-of-the-envelope, frequentist and Bayesian tests. Find out how normality tests are used in statistics, such as linear regression, hypothesis testing and model selection.
Learn about the history, methods and applications of statistical hypothesis testing, a method of statistical inference used to decide whether the data supports a particular hypothesis. Compare the approaches of Fisher, Neyman and Pearson, and their controversies and contributions to the field.
