The researchers reject the <a href=\"https:\/\/www.physiotutors.com\/wiki\/null-hypothesis\/\" target=\"_blank\" rel=\"noopener\">null-hypothesis<\/a> when, in fact, it is true.<\/span>\r\n\r\n[caption id=\"attachment_16661\" align=\"alignnone\" width=\"402\"]<img class=\"wp-image-16661\" src=\"https:\/\/www.physiotutors.com\/wp-content\/uploads\/2023\/06\/Type-2-errors-Akobeng.png\" alt=\"Type 2 errors akobeng\" width=\"402\" height=\"247\" \/> Akobeng (2016), Acta pediatric[\/caption]\r\n<h6>Expressed in Alpha<\/h6>\r\nThe <a href=\"https:\/\/www.physiotutors.com\/wiki\/alpha-level\/\" target=\"_blank\" rel=\"noopener\">alpha level<\/a>, represented by the symbol \u03b1, is set by researchers to limit the probability of type 1 errors. The likelihood of making a type 1 error is represented by the <a href=\"https:\/\/www.physiotutors.com\/wiki\/alpha-level\/\" target=\"_blank\" rel=\"noopener\">alpha level<\/a>. The standard <a href=\"https:\/\/www.physiotutors.com\/wiki\/alpha-level\/\" target=\"_blank\" rel=\"noopener\">alpha level<\/a> is 0.05, which denotes a 5% risk of incorrectly rejecting the null hypothesis.\r\n\r\nBy setting the <a href=\"https:\/\/www.physiotutors.com\/wiki\/alpha-level\/\" target=\"_blank\" rel=\"noopener\">alpha level<\/a> at 0.05, the researcher can firmly reject the null hypothesis and draw the conclusion that there is a significant effect if the <a href=\"https:\/\/www.physiotutors.com\/wiki\/p-value\/\" target=\"_blank\" rel=\"noopener\">p-value<\/a> from statistical analysis is below this cutoff. It is important to keep in mind that the <a href=\"https:\/\/www.physiotutors.com\/wiki\/alpha-level\/\" target=\"_blank\" rel=\"noopener\">alpha level<\/a> is a fixed threshold, therefore researchers must be careful not to consider any results that fall below it to be practically significant or significant.\r\n\r\nNote that the 0.05 level is more a heuristic than a deliberate level. It is important to carefully assess the research environment, potential error repercussions, and the desired balance between preventing type 1 errors and spotting real effects when choosing an appropriate <a href=\"https:\/\/www.physiotutors.com\/wiki\/alpha-level\/\" target=\"_blank\" rel=\"noopener\">alpha level<\/a>.\r\n<h6>Trade-Off: You Win Some You Loose Some<\/h6>\r\nSo why not use an <a href=\"https:\/\/www.physiotutors.com\/wiki\/alpha-level\/\" target=\"_blank\" rel=\"noopener\">alpha level<\/a> of zero so no errors occur? <a href=\"https:\/\/www.physiotutors.com\/wiki\/type-2-errors\/\" target=\"_blank\" rel=\"noopener\">Type 2 errors<\/a> (false negatives) are more likely to occur when type 1 errors are reduced by using a lower <a href=\"https:\/\/www.physiotutors.com\/wiki\/alpha-level\/\" target=\"_blank\" rel=\"noopener\">alpha level<\/a>, such as zero or 0.01. The trade-off between the two sorts of errors emphasizes how crucial it is to carefully weigh the implications and practical value of the research findings when deciding on the right <a href=\"https:\/\/www.physiotutors.com\/wiki\/alpha-level\/\" target=\"_blank\" rel=\"noopener\">alpha level<\/a>. A thorough and sophisticated approach to statistical inference is necessary to strike the correct balance.\r\n<h6>Decreasing Type 1 Errors<\/h6>\r\nDecreasing <a href=\"https:\/\/www.physiotutors.com\/wiki\/type-1-error-rate-control\/\" target=\"_blank\" rel=\"noopener\">type I error rate<\/a> is of utmost importance. In most research papers, the error rate is not controlled. The risk of type I errors keeps climbing, unbeknownst to the researchers. You can spot this quite easily, and even correct it yourself with a back-of-the-envelope calculation.
