A poster presentation, at a congress or conference with an academic or professional focus, is the presentation of research information in the form of a paper poster that conference participants may view. A poster session is an event at which many such posters are presented.
The testing effect (also known as retrieval practice, active recall, practice testing, or test-enhanced learning) [1] [2] [3] suggests long-term memory is increased when part of the learning period is devoted to retrieving information from memory. [4]
In statistics, efficiency is a measure of quality of an estimator, of an experimental design, [1] or of a hypothesis testing procedure. [2] Essentially, a more efficient estimator needs fewer input data or observations than a less efficient one to achieve the Cramér–Rao bound.
There are several advantages to multiple choice tests. If item writers are well trained and items are quality assured, it can be a very effective assessment technique. [5] If students are instructed on the way in which the item format works and myths surrounding the tests are corrected, they will perform better on the test. [6]
Re-administering the same test to the same group at some later time; Correlating the first set of scores with the second; The correlation between scores on the first test and the scores on the retest is used to estimate the reliability of the test using the Pearson product-moment correlation coefficient: see also item-total correlation.
The above image shows a table with some of the most common test statistics and their corresponding tests or models. A statistical hypothesis test is a method of statistical inference used to decide whether the data sufficiently supports a particular hypothesis. A statistical hypothesis test typically involves a calculation of a test statistic.

Use of the term in statistics derives from Sir Ronald Fisher in 1922. [2] Use of the terms consistency and consistent in statistics is restricted to cases where essentially the same procedure can be applied to any number of data items. In complicated applications of statistics, there may be several ways in which the number of data items may grow.
