The results have a real meaning and are not just random D. The results are only important for statisticians 相关知识点: 试题来源: 解析 C。“statistically significant”意味着结果具有真正的意义,不是随机产生的。A 选项“结果不可靠”错误;B 选项“结果可能是偶然的”与题意相反;D 选项“结果只对...
What Does Statistically Significant Mean?Jeff Sauro
The more elements you A/B orMVTtest, the more traffic you’ll need in order to draw statistically significant conclusions you can reasonably trust. If your website doesn’t generate the level of traffic you need to get that kind of sample size, you need to be more selective about what ...
leads. But to be confident that this difference is not just due to chance, you conduct a statistical test and find that the results are statistically significant. This tells you that the difference in performance between the two versions is likely real, and not just a result of random ...
Everything else presents a less drastic difference between the location (expression value) where the major hump lies. In this case, "hump" is the mode, the most frequently occurring expression value. Sometimes it also helps to look at the patterns or clusters in data ...
You believe that variable X directly (positively) affects the value of variable Y. After running a regression, the parameter estimate of X is +0.49 and the t-statistic is 0.03. You would thus conclude that: a. While statistically significant, the paramete ...
As discussed, we can't rely on this p-value for the usual F-test. However, we can still interpret eta squared (often written as η2). This is a descriptive statistic that neither requires normality nor homogeneity. η2 = 0.046 implies a small to medium effect size for our ANOVA....
Statistical significance is a result of hypothesis testing that arrives at a p-value or likelihood that two or more variables are caused by something other than chance. A 5% p-value tends to be the dividing line. The lower the value, the more statistically significant the result of the data...
Is a 0.05 P-Value Significant? A p-value less than 0.05 is typically considered to be statistically significant, in which case the null hypothesis should be rejected. A p-value greater than 0.05 means that deviation from the null hypothesis is not statistically significant, and the null hypothe...
