Bayesian statisticsA testing method to identify statistically significant differences by comparing the significance level and the probability value based on the Null Hypothesis Significance Test (NHST) has been used in food research. However, problems with this testing method have been discussed. Several...
Specifies how InnoDB index statistics collection code should treat NULLs. Possible values are NULLS_EQUAL (default), NULLS_UNEQUAL and NULLS_IGNORED 当变量设置为 nulls_equal 时,所有 NULL 值都被视为相同(即,它们都形成一个 value group) 当变量设置为 nulls_unequal 时,NULL 值不被视为相同。相反,每...
Find thecritical value. When beginning statistics, you usually deal with anormally distributedpopulation, so the critical value will be found with az-score.Use the following formula to find the z-score. Find theP-Valueby looking up your answer from step 3 in thez-table. To get t...
