-Null hypothesis: There is no difference in the base qualities that support the reference allele and the base qualities that support the alternate allele. -Alternate hypothesis: There is a difference in the base qualities that support the reference allele and the base qualities that support the al...
Although there appears to be some relationship between the two variables, is there any reason to believe that the differences in PDA ownership between different income categories is anything more than random variation? A number of tests are available to determine if the relationship between two ...

It is well-known that the testing procedures applying to problem (1)(1) and (2)(2) are tt-test and FF-test respectively. However, the key to explain the posed paradox is recognizing the tt-test to problem (1)(1) can also be viewed as an equivalent FF-test, so that...
1. Chi-square tests. 2. z-tests. 3. t-tests. 4. F-tests. Each of these methods of significance testing is described in this tutorial as well as when to apply the test and how to interpret the results of the test. Chi-Square Test The chi-square statistical test studies the relations...
交叉表列的目的是要顯示兩個變數之間的關係(或沒有關係)。 雖然兩個變數之間看起來似乎有些關係,但是否有任何理由讓我們相信,擁有 PDA 與不同收入類別之間的差異,並非只是隨機的變化? 您可以使用數種檢定來判斷兩個交叉表列變數之間的關係是否顯著。 最常用的檢定之一為卡方檢定。 卡方檢定的一項優點是它幾乎適用...
The present article deals with the controversy about null hypothesis significance testing (NHST) that currently exists in psychological research. The main criticisms and counter-criticisms posed by its detractors and supporters are presented. Alternatives have been proposed to replace or complement the NHS...
Testing a correlation coefficient's significance: Using H0: 0<ρ≤λ is preferable to H0: ρ=0. Psychol Sci. 2007;49:74-87.Kubinger, K. D., Rasch, D., & Simečkova, M. (2007). Testing a correlation coefficient's significance: Using H0: 0 < ρ≤λ is preferable to H0: ρ ...
Continued expectant management with interval fetal testing while awaiting the onset of spontaneous labor is a viable clinical option. A prenatal sonographic diagnosis of TUCK should not serve as the sole indication for cesarean delivery. The main strengths of our study are the large sample size, ...
To avoid a bias caused by follow-up samples, re-testing within six weeks after the initial detection was defined as a single case. Data relating to underlying medical conditions and clinical parameters on the day of RV detection were retrieved retrospectively from patient charts. In the case of...
